碩士 === 華梵大學 === 電子工程學系碩士班 === 102 === LCD (Liquid-crystal display, LCD) are widely utilized in our daily life. You can see the LCD often installed in a variety of electronic products, such as mobile phones, TVs, computers …etc. Along with advances in technology products, LCD continues to be more important. Nowadays, there have many kinds of liquid crystal panels. TFT-LCD panels can be used from 1.2-inch to 60-inch,undersize panels are used in cell phones, small electric screens and EDR ...etc.middle size panels are used in the tablet PC and notebooks ...etc. Large-size panels are used in screen wall , televisions…etc. Which in the resolution of images are also getting better and better. The common main ratio of the screen is divided into 4 to 3 and 16 to 10 The 4 to 3 resolution of image is divided into VGA (640 * 480).This is a display standard of IBM PC.SXGA + (1400 * 1050) are the resolution of image in notebooks between 2007 to 2007.UXGA (1600 * 1400) resolution of images are exactly four times of VGA,it is resolution of many 20-inch and 21-inch screens.16 to 10 resolution is divided into WVGA (800 * 480) which is the first generation of 7-inch Eee PC resolution.WSVGA (1024 * 600) which is 8.9-inch Netbook resolution.WSXGA + (1680 * 1050) resolution is used in 20-inch and 22-inch wide-screen LCD and part of the used in 15.4-inch notebooks.This is very important on the test panels.So, we have to do a test of lighting. To test whether there is a black dot, will it broken or if there are unusual places. This paper all using two TFT-LCD panels for comparison,The biggest difference is the transmission speed of panels. The first one is using VS, HS, DEN, DCLK, and RGB as panel signals. Panel resolutions of 280 * 525 are mainly used in satellite navigation panels. To achieve by using MAX II (EPM1270T144C5N) development version. The second is using MIPI as a signal between panel. Besides using VS, HS, DEN, DCLK and RGB, also using three signals CS, MOSI and SCK of SPI as the signal panels. This panel resolution is 720 * 1280 mainly used in the phone screen panel. which is using the development version of DE2-70 and Cyclone II (EP2C8Q208C8N) to achieve. Mainly because the DE2-70 development version costs too high, so further found Cyclone IV (EP4CE15F17C8N). This board can significantly reduce costs.
