The difference between the mimic panel and digital screen
Claim 1: mimic panel and digital screen screen itself is no different, the main difference is in the circuit. Added to the LCD screen pixel certainly are digital signals. At the edge of the screen there are a lot of driver IC, is known as the drive. Behind the screen of the circuit boards primarily controller, the controller will receive signal is converted to meet the requirements of the drive timing drive signal, to drive, lit the corresponding pixel. Mimic panel and digital screen in the writing part is the same, the difference between them lies in the input. Digital screen directly input digital signal, the RGB signals of each color are video conversion several digital signal processing circuit, directly to the screen control drive, A/D conversion is done in front of the circuit. And mimic panel input is trichromatic analog signal input, it's A/D conversion is done in the circuit on the LCD screen.
Idea 2: this problem has been said many times. The key difference in the input is the RGB signal simulation or Numbers. Pointed out that one of your mistake, the real input to the screen is a specific voltage value, the size of the voltage value determines the deflection of the liquid crystal size, to determine how much through light, can be thought of as drivers need screen is the simulation signal, but definitely not a digital signal (for RGB signal timing signals are digital, of course) input RGB is if the simulation signal, called a screen with the simulation screen, in LCM DRIVER IC internal samples processing, and then send the samples to TFT. Input RGB signal if the number is called digital screen, within the LXM DRIVER IC to be D/A conversion, the job is done by GAMMA correction circuit. I want to add. As shown in figure, this is an equivalent circuit diagram of the LCD panel. When open the red gate line (such as line 3 open), the source driver data (voltage) along the green line down, stored in the Cst storage capacitor (LCD), so this line of points was lit up, and the third line every point of brightness, depending on the size of the storage capacitor on the voltage. So the voltage was simulated, the digital signal itself is no voltage size. Be driven plate of analog signal or digital signal to the source driver IC inside do the transformation. If it is analog signals, the source driver to get corresponding point voltage sampling, then sent to the source (green line). If the input is a digital signal, the source driver to converts digital signals into corresponding point voltage value, and then sent to the source (green line). Digital signal is not directly sent to the source line. Above, don't know if there is any help to everybody, if you still have what not understand place, please continue to post, we discuss together. Use type TFT LCD (LCD panel displays, dot matrix display actively, need to use the source drive (source driver) and gate drives (gate driver) to control the LCD source and gate field effect transistor FET. The source drive receives the display data drive LCD display, also known as data drives (data driver), gate drive control progressive scan.
Statement 3: analog screen input signals are analog RGB signal, the signal to each row and reverse, a line must have the cooperate VCOM signals, above and below - 10 v to + 10 v bias, the vertical resolution of the general about 230; Digital screen input signal and an LVDS and so on several points TTL, usually red, green, blue three colors each with 6 to 8 digits to represent, does not need external bias, vertical resolution is usually more than 400. Actually digital screen with analog screen is done with digital signal drive. Now what is called the digital screen and mimic panel interface to distinguish from the LCD panel, screen is to mimic panel can be directly input analog signals, to the input digital signal is digital screen. Mimic panel more than digital screen an A/D converter, used to convert analog signal to digital signal. Digital screen will deal directly with digital signal to display. Digital screen from its signal transmission way points, can be divided into TTL, an LVDS and so on. Mimic panel and digital screen screen itself is no different, light up when the drive line drive IC are digital signals.
