Character LCD Modules TVs use systems integration reduces design complexity

With conventional CRT TV circuit design is different, because LCD TV requires multiple devices for voice, text, and image processing and system control, the circuit design is too complex. custom lcd
First, LCD TV video content is scaled to fit the formation of the active matrix display rows and columns of the fixed grid, such a high scaling engine by the horizontal and vertical scaling filter.
Secondly, LCD TV requires other adjustments to the signal is displayed on the flat panel display. CRT TV medium and low field frequency of 50Hz and an alternate use of the way to display the video frame, and full use of the LCD TV if the refresh rate of 50 Hz can not do this, it is because the LCD flat panel display to the retention of the entire frame period pixel information until new information is written. For moving images, which implies the need to write the progressive scan full frame information at different times in order to prevent the information recorded on the overlap of the two interlaced frames, the need for signal "de-interlacing." This means that for odd frames, respectively, in the calculation of the information in the odd field, the need to maintain a neat without jagged edges adverse effects, which requires the use of advanced video algorithms.
In addition, the peak white level limit, OLED Display color saturation, contrast, noise reduction algorithms, and also need to be optimized for the LCD. Finally, LCD TV using low-voltage differential signaling (LVDS) or TTL level interface to the video data to the LCD panel.
