2023-02-25 What Are The Main Components Of Liquid Crystal Display? The main components used in the LCD liquid crystal module are: LCD panel, IC, backlight, TP, FPC.If the Liquid Crystal Display Module components are subdivided, they can be divided into: polarizer, glass substrate, Black matrix, color filter, Protective film, Common electrode, liquid crystal, Spacer, Display electrode, TFT, storage capacitor, Glass substrate, polarizer, diffusion plate, Prism sheet, light guide plate, lamp tube, reflector. LCD liquid crystal module In addition, strictly speaking, the circuit driving the backlight module is also a part of the Liquid Crystal Display LCD module. The above complex part is the glass substrate part, which is made of two extremely thin glasses with a micron gap in the middle, filled with liquid crystal molecules, each pixel is an independent liquid crystal cell, and each liquid crystal cell has The electrode is connected to the control unit on the substrate. It should be noted that each pixel here refers to one RGB, not one RGB, so the physical resolution pixel of the liquid crystal should be multiplied by 3, which is the real physical unit Pixels, some special ones like Sharp's new "four-color" LCD panel, add "Y" (yellow) to RGB, and the physical unit pixel is 4 times the nominal resolution...so, on the glass substrate There are a large number of extremely thin electrodes and leads, which are basically transparent and difficult to distinguish with t

2023-02-17 Introduction Source Of Lcd Display Module Liquid Crystal Display (LCD) A type of display used in digital clocks and many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid causes the crystals to rearrange so that light cannot pass through them. Therefore, each crystal acts like a shutter, allowing light to pass through and blocking it. Liquid crystal display (LCD) technology information products are developing towards light, thin, short, and small targets, and display products with a long history in computer peripherals are no exception. Under the premise of being easy to carry and carry, traditional display methods such as CRT image tube displays and LED display panels, etc., are all limited by factors such as excessive size or huge power consumption, and cannot meet the actual needs of users. need. The development of liquid crystal display technology is just in line with the current trend of information products. Whether it is right-angle display, low power consumption, small size, or zero radiation, it can allow users to enjoy a good visual environment. Liquid Crystal Display Module To trace the origin of liquid crystal displays, it is necessary to start with the birth of "liquid crystal". In 1888 AD, an Austrian botanist, Frederick. Friedrich Reinitzer discovered a special substance. He extracted a compound called helical toluate from plants. When doing heating experiments on this compound, he unexpectedly found that this compound has two melting points at different temperatures. And its state is between the liquid and solid substances we usually know, a bit like a colloidal solution of soapy water, but it has both liquid and crystal properties in a certain temperature range, and because of its unique Condition, later named it "Liquid Crystal", is the meaning of liquid crystalline substances. However, although

2023-02-11 What Are The Display Methods Of Black And White Lcd Screens? The basic principle of the Liquid Crystal Display black and white screen is to fill the liquid crystal material between two parallel plates, and change the arrangement of molecules inside the liquid crystal material through voltage to achieve the purpose of shading and light transmission to display different shades. LCD screens are divided into black and white screens according to product types: TN, HTN, STN, FSTN, DFSTN, VA... and other types. LCD black and white screens are divided into: Reflecting Liquid Crystal Display, semi-transmissive and full-transmissive according to the display method. Under normal circumstances, when light is irradiated from top to bottom, usually only one angle of light can penetrate down, and then enter the groove of the upper interlayer through the upper polarizer, and then pass through the channel of twisted arrangement of liquid crystal molecules to pass through the lower polarizer. Form a complete light penetration path. On the other hand, two polarizers are attached to the interlayer of the liquid crystal display, and the arrangement and light transmission angle of the two polarizers are the same as the groove arrangement of the upper and lower interlayers. When a certain voltage is applied to the liquid crystal layer, due to the influence of the external voltage, the liquid crystal will change its initial state, no longer arranged in a normal way, and become an upright state. Therefore, the light passing through the liquid crystal will be absorbed by the two-layer polarizer and the whole structure will be in an opaque state, resulting in black on the display screen. When no voltage is applied to the liquid crystal layer, the liquid crystal is in its initial state and will reverse the direction of the incident light by 90 degrees, thus allowing the

2023-02-04 Precautions For Using Liquid Crystal Display The CCFL (cold cathode lamp) of the backlight is prone to aging, air leakage, broken and other defects. The screen drive circuit is prone to electrical defects due to electrical components, such as ICs and capacitors. LCD screens are prone to defects such as bright and dark spots and lines due to static electricity and foreign objects. The aging of the lamp is mainly distinguished according to the brightness and color. The brightness of aging will decrease, and the color of white light will be yellowish. The aging of Liquid Crystal Display is usually not easy to distinguish, and there will be bright and dark spots or line defects in severe cases. The Liquid Crystal Display Module display will age, because there are semiconductor components inside, and the liquid crystal will also age. The screen and the backlight are separated, but you must not repair it yourself, because the assembly and disassembly of the screen and the backlight are carried out in a clean room and an antistatic environment, which is not acceptable in a normal environment, and the replacement of the lamp tube requires Also remove the backlight, otherwise it may cause damage to the optical material. You can find the manufacturer to repair it. It is not very expensive to just replace the lamp tube, but if the optical material inside is damaged, it will be more expensive. Our factory is managed and operated according to the modern operation mode, with the operation philosophy of providing customers with satisfactory quality, delivery time and service, and the purpose of meeting the needs of customers.

2022-12-30 Introduce The Working Principle Of Lcd Liquid Crystal Screen To put it simply, the basic principle for the screen to complete the display is to fill the gap between the two parallel plates with liquid crystal material or Liquid Crystal Display Module, and then change the arrangement of the molecules inside the liquid crystal material through voltage to achieve shading It can display images with different shades and light transmission, and only need to add a three-color filter layer between the two plates to complete the display of colorful images. The structure of Liquid Crystal Display is to place liquid crystal materials in two parallel glasses. There are many small vertical and horizontal wires in the center of the two glasses. The rod-shaped crystal molecules are controlled by electrification or not, and then change. Direction, the picture produced by refracting its light. It is much better than CRT, but its price is more expensive. Liquid crystal is an organic compound composed of long rod-shaped molecules. In nature, the long axes of these rod-like molecules are roughly parallel. The first characteristic of LCD: liquid crystal must be poured between two planes with fine grooves to work normally. The grooves on these two planes are perpendicular to each other (intersecting at 90 degrees), so that is to say, if the molecules on one plane are arranged north-south, the molecules on the other plane are arranged east-west, and the molecules located on the two sides The molecules between the two planes will be forced into a 90-degree change state. Because the light is transmitted along the direction of the molecules, the light will also be changed by 90 degrees when passing through the liquid crystal. But when a voltage is applied to the liquid crystal, the molecules will be re-arranged vertically, so that the light can go out directly withou

2022-12-17 Advantages And Characteristics Of LCD Liquid Crystal Screen Liquid Crystal Display is an organic compound made of long rod-shaped molecules. In the natural state, the long axes of these rod-like molecules are roughly parallel. The first feature of the Liquid Crystal Display Module is that liquid crystal must be poured between two planes with fine grooves in order to work properly. The grooves on these two planes are perpendicular to each other (intersecting at 90 degrees), that is to say, if the molecules on one plane are arranged in the north-south direction, the molecules on the other plane are arranged in the east-west direction, and the molecules located between the two planes are arranged Forced into a 90 degree twist. Since the light propagates along the direction of the arrangement of the molecules, the light is also twisted 90 degrees when it passes through the liquid crystal. But when a voltage is applied to the liquid crystal, the molecules will rearrange vertically, so that the light can go out directly without any twisting. The second feature of the LCD screen is that it relies on polarizing filters and the light itself. Natural light radiates randomly in all directions, and the polarizing filters are actually a series of thinner and thinner parallel lines. These lines form a net that blocks all light rays that are not parallel to these lines, and the lines of the polarizing filter are just perpendicular to the first one, so it can completely block those light rays that have been polarized. Only when the lines of the two filters are perfectly parallel, or the light itself has been twisted to match the second polarizing filter, can the light pass through. The LCD screen is composed of two polarized filters perpendicular to each other, so under normal circumstances it should block all the light that tries to pass through. However, s

2022-12-10 How To Distinguish Lcd Liquid Crystal Screen And Lcd Backlight The LCD liquid crystal screen is not a common LCD backlight, and the LCD display is also called an electronic display or floating characters. By LCD dot matrix and LCD, PC panel, text, image, animation, video and content are displayed through red, blue, white and green LCD on and off. According to different occasions, different supervision, such as general billboards, these flowing calligraphy can be produced according to the needs of flash animation, stored in the display of the memory card, and then displayed by technical methods, and can be changed at any time according to different needs. The various parts are shown in the modular structure of the device. A traditional LCD screen usually consists of a display module, a control system and a power supply system. The color and luminous efficiency of LCD light Liquid Crystal Display Module emission and production materials and related LCD light bulbs are all blue at the beginning, but later together with phosphors, different light colors are adjusted according to different needs of users, widely used red, green, blue, Yellow 4. Due to the low operating voltage of the LCD, it can actively emit light and have a certain brightness, brightness and voltage adjustment, and it is shock-resistant, anti-vibration, and has a long life (100,000 hours). Therefore, there are no other display methods and LCDs in large-scale display devices. LCD screen matches. Red and green LCD chips or lamps are made together as pixels to display so-called black and white or monochrome screens and three-color or two-color screens, red, green and blue LCD chips or discharge lamps are used together as a pixel display called three-color screens or Full color screen. If there is only one color, it is called monochrome. The pixel size of the indoor LCD screen is generally 2-16mm, which is often used to make a variety o

2022-10-27 The Working Principle Of The LCD Display Module Simply put, the basic principle of screen display is to fill the liquid crystal material between two parallel plates, and change the molecular arrangement inside the liquid crystal material by voltage, so as to achieve the purpose of shading and transmitting light to display images of different depths. Paste the image, and as long as the three-color filter layer between the two plates, the color image display can be realized. Liquid crystal display is the abbreviation of liquid crystal display. Liquid crystal displays are liquid crystals placed between two parallel sheets of glass with many thin vertical and horizontal lines between them. The rod-like crystal molecules change direction and refract light to create images, whether electrical or electrical. Better than crt, but more expensive. Liquid crystals are organic compounds composed of long rod-like molecules. In nature, the long axes of these rod-like molecules are roughly parallel. The first feature of LCDs is that they must fall between two recessed surfaces to function properly. The grooves of the two planes are perpendicular to each other (90 degree crossing) This means that if the molecules of one plane are aligned north-south, then the molecules of the other plane are aligned east-west, and the molecules between the two planes are forced to be 90 degrees twist. Light travels in the direction of the molecule, so when it passes through the liquid crystal, it is also twisted 90 degrees. But when a voltage is applied to the liquid crystal, the molecules are rearranged vertically so that light can be emitted directly without being twisted. The second feature of LCD is that it relies on polarizers and the light itself, which scatters randomly in all directions. A polarizer is actually a series of increasingly thin parallel lines. The lines form a grid that blocks all rays that are not parallel to them.

Beautiful images. The main imaging device of an LCD projector is a liquid crystal panel. The volume of an LCD projector depends on the size of the LCD panel, the smaller the LCD panel, the smaller the projector is. According to the electro-optic effect, liquid crystal materials can be divided into two categories: active liquid crystal and inactive liquid crystal, among which active liquid crystal has high light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system. Like LCD monitors, LCD projectors use twisted nematic liquid crystals. The light source of the LCD projector is a special high-power bulb, and the luminous energy is much higher than that of the CRT projector that uses fluorescent light, so the brightness and color saturation of the LCD projector are higher than that of the CRT projector. The pixel of the LCD projector is the liquid crystal unit on the liquid crystal panel. Once the liquid crystal panel is selected, the resolution is basically determined, so the function of adjusting the resolution of the LCD projector is worse than that of the CRT projector. LCD projectors can be divided into single-chip and three-chip types according to the number of internal liquid crystal panels. Most modern LCD projectors use three-chip LCD panels (Figure 1). The three-chip LCD projector uses red, green, and blue liquid crystal panels as the control l

2022-08-16 What Are The Advantages Of Lcd Monitors? The quality of LCDs has improved slightly so from a demand point of view the current dot matrix design is gaining acceptance in the market so from an advantage and market point of view this is a good example of improvements to the screen and traditional designs . Good product development can also be combined with market demand to better help users promote their use. First of all, the practicality of the dot matrix LCD is a design product developed in recent years. At present, the good design and use of the LCD is quite reasonable for users. Improvement and comprehensive adjustment of product requirements are also an advantage of products to user needs. It is also a standard item in display design and use, which is cost-effective and cost-effective. Therefore, not only LCDs, but also in terms of quality and product procurement are well promoted, using a wide range of services to seize the current market and improve the performance of services. Third, safety and reliability are also issues that should be considered when choosing a liquid crystal display, whether it is actually the focus of the user's attention, or the combination of the rationality of the price and the actual function of the product, etc. Therefore, the selection and adjustment of the screen are upgraded. More realistic to grasp the security of the service and the reliability of the product, make a good comprehensive upgrade in case of problems or failures. Dot matrix design is a distinctive feature of current display designs. It is also a good change to master the adjustment mode of the current product design and combine the individual needs of the product, the development of the market and the overall use of the product.
