日立公司的TM26D02VC是专为要求高分辨率彩色显示的工作站和视频显示设备(VDU)终端设计的10英寸有源矩阵液晶显示(LCD)板。该显示板的象素分辨率为640×480,与通常的VGA格式兼容,具有使每个象秦都能以8种颜色中显示一种(包括黑白)的滤色片。此外,它内部还含有视频数据转换电路,使之能直接接收CRT的信号。在传统点矩阵LCD中,X和Y条状电极淀积在上下玻板上,各个象素由X和Y电极相交处构成。用这种方法,由于象素间的电容耦合,在不降低对比度的情况下难以驱动大型阵列。当用有源矩阵寻址时,通过插入非线性元件减弱象素间的耦合,达到提高对比度及增加
Hitachi’s TM26D02VC is a 10-inch active matrix liquid crystal display (LCD) board designed for workstation and video display device (VDU) terminals that require high-resolution color displays. The display panel has a pixel resolution of 640x480 and is compatible with the usual VGA format, with color filters that enable each to display one (including black and white) in eight colors. In addition, it also contains video data conversion circuit inside, so that it can directly receive the CRT signal. In conventional dot matrix LCDs, X and Y strip electrodes are deposited on the upper and lower glass plates, with each pixel being formed by the intersection of the X and Y electrodes. In this way, due to the capacitive coupling between pixels, it is difficult to drive a large array without reducing the contrast. When addressing with an active matrix, the coupling between the pixels is attenuated by inserting non-linear elements to increase the contrast and increase
