Problems solved by technology
[0003] In the liquid crystal on silicon panel, the wrong connection of the signal line may cause the driving signal to not be correctly transmitted to the pixel unit, and the resistance of the signal line itself or other factors, such as process variation, will also cause the driving signal to attenuate during transmission

The invention provides a silica-based liquid crystal panel comprising a display region, an odd data driver, an even data driver and a data wire test unit. The display region is provided with a plurality of pixel cells respectively arranged at the cross position of a plurality of scanning wires and a plurality of data wires, wherein the data wires comprise a plurality of odd data wires and a plurality of even data wires. The odd data wires are respectively coupled with a plurality of first data channels of the odd data driver, and the even data wires are respectively coupled with a plurality of second data channels of the even data driver. The odd data driver and the even data driver are arranged at a first side of the display region. The data wire test unit is arranged at a second side ofthe display region, selects signals according to the data wires and selectively outputs a data wire test signal corresponding to one of the data wires. The second side corresponds to the first side.
Description
technical field [0001] The invention relates to a silicon-based liquid crystal panel, and in particular to a plane layout of a silicon-based liquid crystal panel. Background technique [0002] Liquid crystal on silicon (LCOS) is a micro-display technology. Compared with liquid crystal display (liquid crystal display) technology, liquid crystal on silicon technology has higher image resolution and can be used at a lower cost. Manufacturing large-screen high-definition television (high-definitiontelevision, HDTV). figure 1 It is a layout diagram of a traditional liquid crystal on silicon panel. Please refer to figure 1 , the liquid crystal on silicon panel 100 mainly includes a scanning driver 110, a data driver 120, a signal processing unit 130 and a display area 140, wherein a plurality of pixel units (not shown in figure 1 ) are arranged in the display area 140 in an array, and each pixel unit is coupled to a scan line 111 and a data line 121 thereof. The signal process...
