Question: What does LCD module mean? You mean LCM? We usually refer to the liquid crystal module as LCM for short, which is actually the whole assembly of liquid crystal display without shell, including backlight (backplane, LED lamp, reflective film, LGP, upper and lower diffusion film, brightness enhancement film), that is, the so-called B/L, and the opening composed of glass substrate, PCB board and liquid crystal. Together with the perforated shell, backlight power supply and LVDS signal, it is a * * * LCD!

Question 2: What's the difference between LCD and LCD? It is easy to be confused. Modules generally refer to black and white screens, while modules generally refer to color display, sometimes mixed. Shenzhen yuhua micro-technology professional custom LCD screen.

Question 3: What's the difference between LCD module and LCD panel? The module integrates a driver module, which can be used with it, but it is not flexible enough and can only be used according to its requirements. There is only one LCD on the panel, and the driving circuit should be designed by itself. You can design the driving circuit according to your own requirements.

Question: What does tft mean? Tft (thin film transistor) is the abbreviation of thin film transistor. TFT display screen is the mainstream display device on all kinds of notebook computers and desktops. Each LCD pixel on this display screen is driven by a thin film transistor integrated behind the pixel, so the TFT display screen is also an active matrix LCD device. This is one of the best LCD color displays. TFT display has the advantages of high responsiveness, high brightness and high contrast, and the display effect is close to CRT display.

At the same time, TFT screens are also widely used in mid-to high-end color screen mobile phones, which are divided into 65536 colors, 1.6 million colors and 1.6 million colors, and the display effect is excellent.

TFT means that each LCD pixel is driven by a thin film transistor integrated behind it. Therefore, it can display screen information with high speed, high brightness and high contrast. TFT-LCD (Thin Film Transistor Liquid Crystal Display) is one of the most common liquid crystal displays.

Question 5: What is the LCD module and its difference from the LCD panel? Excuse me, what is LCD module, and what is the difference from LCD panel? A: TN+ membrane technology is to add a wide-angle compensation film on the original basis. This compensation film can increase the viewing angle to about 150 degrees, which is a simple and easy method and widely used in liquid crystal displays. But this technology can't improve the performance such as contrast and response time. Perhaps TN+ film is not the best solution for manufacturers, but it is the cheapest solution, so most manufacturers in Taiwan Province Province use this method to build 15 inch LCD.

IPS(IN-PLANE -SWITCHING) technology claims that it can make the visual angle of up, down, left and right reach 170 degrees. Although IPS technology increases the viewing angle, using two electrodes to drive liquid crystal molecules requires more power consumption, which will increase the power consumption of liquid crystal displays. In addition, it is fatal that the response time of driving liquid crystal molecules will be very slow.

MVA (multi-domain vertical alignment) technology, the principle is to add protrusions to form multiple visual areas. Liquid crystal molecules are not completely vertically aligned at rest, but horizontally aligned after voltage is applied, so that light can pass through each layer. MVA technology improves the viewing angle to more than 160 degrees, and provides shorter response time than IPS and TN+ films. This technology was developed by Fujitsu. At present, Chi Mei in Taiwan Province Province (Chi Li is a subsidiary of Chi Mei in Chinese mainland) and AUO in Taiwan Province Province are authorized to use this technology. VX2025WM is the representative work of this kind of panel. Horizontal vertical viewing angle 175 degrees, basically no visual dead angle, no bright spot promised. Perspective can be divided into parallel perspective and vertical perspective. The horizontal angle is centered on the vertical central axis of the liquid crystal, and the angular range of the image can be clearly seen by moving left and right. The vertical angle is centered on the parallel central axis of the display screen, and the angle range of the image can be clearly seen by moving up and down.

Question 6: What is the display module of the mobile phone? If the shell of the mobile phone is removed, the keyboard is also removed, leaving a screen, that is, the display module. The answer is so difficult that I didn't give it to you.

Question 7: What is the LCD module? Which quality is better? Wu Hanyou's family name is Gu Xinkeji, who specializes in military wide-temperature color liquid crystal display module, but it also has ordinary conventional applications. Suggest going to official website to check the information.

Question: What do OLB and ILB in LCM module mean in LCD industry? Ask experts for advice. Label: Automatic adhesive tape bonding

Chips on glass and COF

The above three technologies are IC package or embedded connection technology.

ILB: The bonding of internal leads is usually the bonding process of guide wires on the glass surface. (The pre-process of this is more complicated. )

OLB: Bonding of external leads usually refers to ACF gluing and other processes. The action block is different.

Question 9: What does the LCD module system include? Which range is larger than the display system? 10 is not a concept, so there is no way to compare it.

The other two are too wide and have a lot of overlapping parts.

So this question can't be answered.

Question 10: Electronic technology, what is the basic unit of Led display module, which is determined by the circuit and installation structure, has the display function and can be realized by simple assembly;
