Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings. It should be noted that the directional terms mentioned in the examples, such as "upper", "lower", "middle", "left", "right", "front", "rear", etc., are only referring to the directions of the drawings. Therefore, the directions used are only for illustration and are not intended to limit the protection scope of the present invention.

[0018] see figure 1 and 2 , a VA liquid crystal display with color polarized light, which consists of a surface polarizer 1, a liquid crystal display layer, an upper bottom polarizer 3, a colored transparent ink layer 4, a lower bottom polarizer 5 and a backlight layer 6 from top to bottom.

[0019] The liquid crystal display layer adopts the existing structure, which is mainly composed of tw...

Abstract

The invention discloses a VA liquid crystal display screen with colored polarized light. The VA liquid crystal display screen comprises a liquid crystal display layer and a backlight layer, wherein acolored transparent ink layer is added between the liquid crystal display layer and the backlight layer; and the colored transparent ink layer presents the same color as a whole or presents differentcolors in different areas. A traditional black-and-white VA liquid crystal display screen is changed into a local colored VA liquid crystal display screen through adding the colored transparent ink layer between the liquid crystal display layer and the white backlight layer. The colored transparent ink layer is arranged between two polarizing plates, so that the problems, such as falling caused bya scratch or discoloration under high-temperature and high-humidity conditions, of colored transparent ink in the processes, such as assembling, testing and the like can be solved.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a VA liquid crystal display with color polarized light. Background technique [0002] Compared with TN LCD, VA (Vertical Alignment) liquid crystal display is used in middle and high-end equipment, such as car display and audio display, because of its high contrast and wide viewing angle. screen and high-end instrumentation display, etc. The traditional black and white VA liquid crystal display is mainly composed of a liquid crystal display layer and a white backlight layer; the liquid crystal display layer displays white characters on a black background under a white backlight. However, the simple black-and-white display screen is not suitable for the display requirements of high-end equipment. For example, some equipment requires the LCD screen to display other colors. When different areas display different colors, the traditional black and white VA LCD screen is helpless. For this...
