Problems solved by technology

The VA-LCD is black when it is not powered on, and it is white after it is powered on. In the prior art, a whole display is often installed on the part of the VA-LCD corresponding to the TFT to display the picture through the lower TFT. From the overall appearance, the TFT The display screen has obvious surrounding boundaries through VA-LCD, giving people an abrupt visual conflict

Embodiment 2

[0024] In this embodiment, the first gradient structure includes a row of horizontal trapezoidal hollowed-out units 32 arranged vertically, such as figure 2 shown. The length h1 of the bottom side of the horizontal trapezoidal hollowed-out unit 32 is 0.2-1.0mm, the length h2 of the top side is 0-0.1mm, the height L is 0.5-5.0mm, and the distance between two adjacent horizontal trapezoidal hollowed-out units 32 is d 0.01-0.05mm.

[0025] There are two kinds of embodiments of the second tapered structure, namely Embodiment 1 of the second tapered structure and Embodiment 2 of the second tapered structure.

[0026] Embodiment 1 of the second gradient structure:

[0027] In this embodiment, the second gradient structure includes a plurality of circular hollowed-out units, the diameter of the circular hollowed-out units gradually becomes smaller from the edge of the second gradient structure to the inside, and the distance between two adjacent circular hollowed-out units From t...

Abstract

The invention discloses a vehicle-mounted liquid crystal display with a soft screen border and combination of a broken code screen and a TFT. The vehicle-mounted liquid crystal display comprises a front polarizing plate and a rear polarizing plate. Front glass is arranged at the bottom of the front polarizing plate. Rear glass is arranged at the top of the rear polarizing plate. A TFT module is arranged at the bottom of the rear polarizing plate. A liquid crystal layer is arranged between the front glass and the rear glass. A front ITO layer and a front PI layer are sequentially arranged between the liquid crystal layer and the front glass from top to the bottom. A rear PI layer and a rear ITO layer are sequentially arranged between the liquid crystal layer and the rear glass from top to the bottom. The edge of the part, which directly faces the TFT module, of the front ITO layer is a first gradation structure and / or the edge of the part, which directly faces the TFT module, of the rear ITO layer is a second gradation structure. According to the invention, the border transmitted by a TFT display screen is softened, and thus visual conflict is reduced.

Description

technical field [0001] The invention relates to a vehicle-mounted liquid crystal display, in particular to a vehicle-mounted liquid crystal display with a combination of a code-breaking screen and a TFT with soft picture borders. Background technique [0002] The vehicle-mounted full LCD display replaces the traditional mechanical instrument panel with a large-sized LCD screen, which can not only display basic driving information, but also display navigation information and entertainment information. This LCD screen is set directly in front of the driver, which greatly facilitates the driver to browse information and improves driving safety. [0003] Due to the low cost of VA-LCD mold opening and the flexibility and variety of sizes, vehicle-mounted LCD displays mostly use large-size VA-LCDs with TFT structures. The VA-LCD is black when it is not powered on, and it is white after it is powered on. In the prior art, a whole display is often installed on the part of the VA-LC...
