Embodiment Construction

[0035] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0036] The invention provides a reflective screen with adjustable light transmission, which improves the clarity of reflection content.

[0037] Such as Figure 1-Figure 2 Shown is a reflective screen with adjustable light transmission according to the present invention, comprising a liquid crystal light blocking layer 1 and a light reflecting layer 2 bonded to each other. The liquid crystal light blocking layer includes liquid crystal glass 101 and is bonded on both sides of the liquid crystal glass In the polarizer 102, the reflective layer includes a coated glass 21 and a semi-reflective semi-transparent film 22 plated on the coated glass, and the coated glass is bonded and connected to the polarizer.

[0038] In the specific implementation process, in order to prevent damage to the semi-reflective semi-permeable membrane and increase...

Abstract

The invention discloses a light transmission adjustable reflection screen, a control device and a display system with the reflection screen and the control device. The light transmission adjustable reflection screen comprises a liquid crystal shading layer and a reflection layer; the liquid crystal shading layer comprises liquid crystal glass and Polaroids at the two sides of the liquid crystal glass; and the reflection layer comprises coated glass connected with the Polaroids and a semi-reflection semi-transmission film connected with the coated glass. The reflection screen can change the light transmittance of itself under different illumination intensities to improve the sharpness of reflected content, and when the screen is applied to a head up display, a user can see the display content needless of lowering the head in the driving process.

Description

Technical field [0001] The invention belongs to the technical field of head-up display, and specifically, is a reflective screen with adjustable light transmittance, a control device and a display system using the same. Background technique [0002] HeadUp Display, hereinafter referred to as HUD, is currently a flight aid instrument commonly used on aircraft. Head-up means that the pilot can see the important information he needs without having to lower his head. HUD uses the principle of optical reflection to project important flight-related information on a piece of glass. The current automotive HUD is derived from the head-up display of the aircraft. The current vehicle-mounted HUD display generally adopts the method of coating a reflective film on transparent glass or plastic to realize the transflective display of the image, and complete the fusion display of the external environment and the displayed content. However, when this method encounters strong ambient light outs...
