Embodiment Construction

[0032] Figure 8 It is a schematic diagram of a pixel electrode arrangement of the present invention.

[0033] See Figure 8 In the above-mentioned liquid crystal display device, the A pixel electrode and the B pixel electrode can be joined together in V-shape and M-shape respectively to form a rectangle. In the above embodiment, the storage capacitor coupling mode of the B pixel electrodes on the odd and even columns can also be exchanged, that is, the storage capacitors of the B11, B13...Bn-1 pixels on the scanning line G1 in the first row are coupled to On the scan line G3, the storage capacitors of B12, B14...Bn pixels are coupled to the scan line G2, and the storage capacitors of A11, A12, A13...A1n pixels are coupled to the common electrode Vcom . The pixel coupling methods on the scan lines G2-Gm are analogized in turn. The storage capacitors of Bm1, Bm3...Bm-1 pixels on the m-th scan line Gm are coupled to the scan line Gd2, Bm2, Bm4. .. The storage capacitor of th...

Abstract

The invention discloses a liquid crystal display device, comprising a plurality of pixels in m rows and n lines while each pixel comprises a pixel electrode A and a pixel electrode B; a plurality of scanning lines for providing scanning drive signals for each pixel row; a plurality of public electrode lines for providing a public voltage signal for each pixel row; a plurality of data lines for providing data signals for each pixel line, wherein the pixel electrode A of each pixel of the i-th row is connected with the present public electrode line, the pixel electrodes B of two adjacent lines of the i-th pixel are respectively and alternatively connected with the scanning lines of the i+1-th row and the i+2-th row, 0<i<=m, m and n are positive integers. The liquid display device resolves the display error caused by the prior pixel structure to resolve the color error in side observation of a panel which liquid crystals are oriented vertically.

Description

Technical field [0001] The invention involves a LCD display device, especially the vertical matching LCD display device that improves the improvement of the side color bias. Background technique [0002] In the wide -viewing angle technology of LCD monitors, vertical aligned (VA) is widely used.However, when observing the liquid crystal display panel of the VA from the side, the phenomenon of bias occurs. [0003] In order to improve this phenomenon, Fujitsu proposed to divide a sub -pixel into two parts (A pixels and B pixels). By adding different voltages to A pixel and B pixelmethod.The current driving methods include capacitive coupling (CC) and dual crystal tube type (TT).CC types include A pixels, B pixels, and capacitors between coupling between B pixels. The CC type has a defect: due to the different brightness of B pixels in high gray steps, it will reduce the overall brightness.TT types open two TFTs at different times, and then apply different voltages, so the frequen...
