Problems solved by technology

But when you wear this kind of sunglasses and observe the car display screen, you will find that the display screen is black. The reason is that the light passing through the polarizer on the outer layer of the LCD is parallel to the polarization direction of the sunglasses, and the horizontally polarized light is absorbed, so it passes through the liquid crystal display. The emitted light is absorbed by the sunglasses, so the display screen cannot be seen, which affects the display and use of navigation and other functions during driving

Abstract

The invention discloses a vehicular touch display screen which comprises an array substrate, liquid crystals, a color film substrate, a polarizer, a touch layer, a touch substrate and a film lambda / 4 wave plate, wherein the film lambda / 4 wave plate is adhered with the polarizer through double-sided adhesives, and the touch layer is positioned between the film lambda / 4 wave plate and the touch substrate. By the aid of the film lambda / 4 wave plate, linearly polarized light emitted by an LCD (liquid crystal display) passes the film lambda / 4 wave plate and the touch layer and becomes circularly polarized light, so that human eyes can see the light of the display screen, and display of navigation and other functions in the driving process is ensured.

Description

Technical field [0001] The invention belongs to the technical field of auto parts, and specifically, the invention relates to a vehicle-mounted touch screen. Background technique [0002] With the development of smart cars, users' requirements for car experience are gradually increasing. Demand for on-board touch screens is increasing year by year, and high-end cars have higher requirements for on-board displays. During driving, when the sunlight is strong, the driver needs to wear sunglasses. Sunglasses generally have the function of polarization, filtering the unordered strong light from the outside into light that vibrates in one direction, making the eyes look more comfortable. But when you look at the car display with this kind of sunglasses, you will find that the display screen is black. The reason is that the light passing through the LCD outer polarizer is parallel to the polarization direction of the sunglasses, which absorbs the horizontally polarized light, so it pass...
