LCD 调试总结（国外英文资料） The diode in the line is also a type of vulnerability, and the backlight is a lot more than that the diode broke down on the 10th of 2009, 2009 (1) liquid crystal display mode Parallel: MCU interface, RGB interface, Vysnc interface Serial: SPI interface, MDDI interface (2) screen color In essence is the levels of the concept of levels is said mobile phone LCD screen brightness strength index, standard, also is called colour gradations of color the color screen mobile phone index can be divided into three levels, from low to high minimum monochrome, followed by 256, 4096, 4096 color color; Currently the highest as the color of 256 = 260000, namely eight color, in law, 65536 color = 2 to the power of 16, known as 16-bit true color, 260000 = 2 18 power, namely 18 truecolor actually 65536 color has been basically can be satisfied with our naked eye identification requirements (3) resolution The resolution of the LCD and CRT display different, generally cant adjust, it is the resolution of the manufacturers have set up and regulations refers to how many pixels in each row, each column on the screen how many pixels to the resolution of the mobile phone, LCD is generally 176 x 220 lines of QCIF QVGA display mode and 240 x 320 line display mode (4) refresh rate LCD refresh rate refers to the display frame frequency, that is, the time required to refresh a frame screen, with screen scanning speed and the ability to avoid screen flicker related meaning refresh rate is too low, led display can be produced to screen images flashing or jitter (5) the visual Angle Monitored in different directions clearly all the content on the screen of the Angle, and it is DSTN or TFT LCD has much to do because the former is to rely on the transistor scanning light-emitting screen on both sides of the screen, the latter is to rely on their own every pixel at the back of the transistor, the difference of the contrast and brightness, decided they have bigger difference between th
