Embodiment Construction

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

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

[0037] Such as Figure 1-Figure 2 Shown is a light-transmitting adjustable reflective screen according to the present invention, which includes a liquid crystal light-blocking layer 1 and a light-reflecting layer 2 that are bonded to each other. The polarizer 102, the reflective layer includes a coated glass 21, and a semi-reflective and semi-permeable film 22 coated on the coated glass, and the coated glass is bonded to the polarizer.

[0038] In the specific implementation process, in order to prevent the damage of the semi-anti-semi-permeable membrane and improve the service life of the semi-anti-semi-permeable membrane, such as figure 2 Shown is another embodiment of the reflective scr...

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 relates to a reflective screen with adjustable light transmittance, a control device and a display system using the same. Background technique [0002] Head Up Display (Head Up Display), hereinafter referred to as HUD, is a flight aid commonly used in aircraft. Head-up means that the pilot can see the important information he needs without looking down. HUD uses the principle of optical reflection to project important flight-related information on a piece of glass. The current car 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 semi-transparent and semi-reflective display of the image, and complete the fusion display of the external environment and the display content. However, when this method encounters strong ambien...
