Embodiment Construction

[0017] FIG. 2 depicts a primary pixel 2 of the liquid crystal display device of the present invention. The present invention divides the current pixel 2 into three regions by providing three different voltage levels to a first electrode terminal 211, a second electrode terminal 221 and a third electrode terminal 231 of the current pixel 2, namely the first electrode terminal 231. A first area 21 , a second area 22 , and a third area 23 . The liquid crystals in the three regions 21, 22, 23 will present different angles according to the three different voltages. Since each voltage creates four quadrants, the sub-pixel of the present invention has twelve quadrants.

[0018] FIG. 3 depicts a schematic diagram of a display device applying the pixel control device of the present invention. The display device 3 includes a display array 31 and a driving control device 32 . The display array 31 has a plurality of pixels 311, and each pixel 311 includes a plurality of sub-pixels for ...

Abstract

The invention relates to a pixel control device and a display device applying the pixel control device. And the pixel control device is connected to a subpixel region to supply a first voltage reference, a second voltage reference and a third voltage reference to this subpixel region to make liquid crystal of the display device presented at different angles so as to solve the problems of gray scale inversion and whiteness at large visual angle. And one scan line of the pixel control device is used to control the startup of a first transistor, a second transistor and a third transistor, and a first data line and a second data line of the pixel control device are respectively used to supply a first data voltage reference and a second data voltage reference to determine the first, second and third voltage references.

Description

【Technical field】 [0001] The present invention relates to a pixel control device and a display device; more specifically, it relates to a pixel control device and a display device matched with a multi-section vertical alignment technology. 【Background technique】 [0002] Due to technical and material limitations, early liquid crystal display screens provided smaller viewing angles, lower contrast ratios, and fewer pixels. Due to the small size of the early liquid crystal display screens, the configured devices are all small portable devices such as notebook computers, mobile phones, and personal digital assistants. Therefore, the viewing angle of the liquid crystal display screen is not a key factor in determining its quality. However, in recent years, many manufacturers have launched large-size LCD screens, which are suitable for desktop personal computers or TVs. At this time, the size of the viewing angle has become a key factor in the quality of the LCD screen. [0003]...
