Problems solved by technology

The above display methods can display relatively clearly when the ambient light is not strong, but when the ambient light is strong, the brightness of the display device can only be increased to achieve a high enough contrast, which will significantly increase the power consumption of the display device
In addition, the projection display method needs a certain space to project a certain size screen, and the transmittance of the transparent OLED display method is low, only 40-50%

Embodiment 1

[0053] This embodiment provides a transparent display panel based on polymer stabilized liquid crystal, using polymer stabilized liquid crystal (Polymer Stabilized Liquid Crystal, referred to as PSLC) as the control medium to realize intelligent transparent display (Transparent Display), in order to realize vehicle-mounted head-up display Functions offer entirely new options.

[0054] The display panel includes a basic display screen, a control unit and a light source. The structure of the display panel is as follows: figure 1 As shown, the planar structure is as figure 2 shown.

[0055]The basic display screen 1 adopts an ultra-narrow frame or frameless design, and the basic display screen 1 is divided into a plurality of pixel areas 10, and each pixel area 10 is provided with a pixel structure and a control element, and the pixel structure at least includes a polymer-stabilized liquid crystal The liquid crystal layer, the control element is used to control the opening of ...

Embodiment 2

[0072] This embodiment provides a display panel based on polymer stabilized liquid crystal transparent display, using polymer stabilized liquid crystal (Polymer Stabilized Liquid Crystal, referred to as PSLC) as the control medium to realize intelligent transparent display (Transparent Display), in order to realize the vehicle-mounted head-up display function Provides entirely new options.

[0073] Normally, when the external ambient light is strong, even if the light source installed on the side is turned on, the display contrast will drop significantly. To solve this problem, the structure of the display panel is further optimized. Different from Embodiment 1, the display panel of this embodiment is also provided with a light-adjustable display screen 3 to adjust the strong ambient light outside.

[0074] Such as Figure 4 As shown, a light-adjustable display screen 3 is added on the display side of the basic display screen 1 in Embodiment 1. The light-adjustable display s...

Embodiment 3

[0085] For the display panel in Embodiment 2, such as Figure 5 As shown, it is possible to Figure 4 The structure shown is further optimized, and the two substrates of the light-adjustable display screen 3 and the basic display screen 1 are combined into one, thereby further reducing the thickness of the product box and improving light transmittance and reliability.

[0086] corresponding, Figure 5 relatively Figure 4 The fourth substrate 307 and the auxiliary adhesive layer 402 can be omitted, and the structure is simpler and thinner.

[0087] The display panel in embodiment 1-embodiment 3 can be: desktop computer, tablet computer, notebook computer, mobile phone, PDA, GPS, vehicle display, projection display, video camera, digital camera, electronic watch, calculator, electronic instrument, meter , LCD panels, electronic paper, televisions, monitors, digital photo frames, navigators and any other products or components with display functions, which can be applied to m...

Abstract

The invention belongs to the technical field of display and particularly relates to a display panel, a display method and a vehicle-mounted head-up display system. The display panel comprises a basicdisplay screen, a control unit and a light source, wherein the basic display screen is divided into multiple pixel areas; a pixel structure and a control element is arranged in each pixel area, the pixel structure at least comprises a liquid crystal layer containing PSLC (polymer stabilized liquid crystal), and the control element is used for controlling the opening of the PSLC to control the light transmission of the pixel area; the control unit comprises an optical sensor and an optical controller which are electrically connected, the optical sensor is used for acquiring ambient brightness,and the optical controller controls light emitting brightness of the light source according to the ambient brightness. The display panel realizes transparent display on the basis of the PSLC, can convert the display modes according to the environment and has the advantages of high transparency, high contrast ratio, low power consumption and high display response speed.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a display method and a vehicle-mounted head-up display system. Background technique [0002] The vehicle head-up display system has been widely favored by high-end cars. Through the head-up display system, various information of the vehicle can be displayed on the windshield glass or two meters in front of the car, that is, in the driver's direct field of vision. This type of display is characterized by high transparency and contrast, which can display auxiliary information (such as vehicle speed, navigation prompt information, auxiliary reminder information from vehicle condition monitoring system and active cruise control system, etc.), which can reduce the driver's head-down and Turn your head to look at the instrument and the central control display without blocking the driver's line of sight. [0003] Currently reported vehicle-mounted head-up ...
