Liquid crystal display screen with visual angle deflection function

Abstract

The invention discloses a liquid crystal display screen with a visual angle deflection function. The liquid crystal display screen comprises a directed diffusion film, a binding layer and an optical module, wherein the directed diffusion film, the binding layer and the optical module are sequentially arranged from top to bottom; a micro-structure is arranged on the upper surface of the directed diffusion film and is used for realizing a light deflection effect; and the binding layer is formed by an optical adhesive and is used for destroying a total reflection phenomenon in the optical module. According to most existing display equipment, particularly display screens applied to airplanes, the main visual angles of the display equipment are all perpendicular to the normal directions of the liquid crystal screens; due to the limitation of the space positions of aircraft cabins, the observation visual angles of pilots deviate from normal lines, and the brightness attenuation of the observation visual angles is large, and as a result, the pilots cannot see information displayed on the screens, however, with the liquid crystal display screen with the visual angle deflection function adopted, the problem in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display screen with viewing angle deflection. Background technique [0002] Liquid crystal displays are more and more common in daily life, but the main viewing angle of most display devices is perpendicular to the normal direction of the liquid crystal screen. In some special cases, such as the space limitation of the aircraft cockpit, it is required that the main viewing angle direction of the LCD screen deviates from the normal line, which is convenient for the pilot to observe. Due to the limited spatial position of the aircraft cockpit, the pilot's viewing angle deviates from the normal line, and the brightness attenuation is large, which makes it difficult for the pilot to see the information displayed on the screen. The LCD screen is called the "eyes" of the pilot. Due to the limited space of the aircraft cockpit, in some cases the pilot needs to obs...

AI Technical Summary

Problems solved by technology

Experiments show that when the main luminous angle is perpendicular to the normal line of the LCD screen, the larger the angle between the viewing angle and the direction of the main luminous angle of the LCD screen, the larger the specular emission and the faster the brightness decays. Therefore, the relationship between the observation angle and the main luminous angle The larger the included angle, the worse the observation effect
