Inclined view angle LCD device

Abstract

The invention provides a strabismus-angle liquid crystal display device. A combined structure of a protuberant reflection prism and a transparent ITO electrode is used on an upper base plate of the liquid crystal display device, a combined structure of a reflection electrode and a transparent opening is used on a lower base plate, thus, light emitted from a backlight source is reflected on the reflection electrode of the lower base plate by the reflection prism of the upper base plate after passing through the opening part of the lower base plate, then the light is reflected to the transparent electrode of the upper base plate and is emitted to the outside of the upper base plate via the reflection electrode. The invention can achieve the purpose of protecting the privacy of the vision at different angles by regulating design parameters such as the angle of the reflection prism and the width of the opening, so as to obtain the vision scope at a specific angle and achieve the purpose of obtaining clear images at the specific angle.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device with a reflective prism at an oblique viewing angle. 【Background technique】 [0002] As a leader in flat panel displays, TFT-LCD has gradually occupied a dominant position in the field of displays. However, when observing a large-screen TFT-LCD, the viewing angles of the human eye at the center and edge of the screen are inconsistent, resulting in distortion of the display screen in terms of brightness, chromaticity, contrast, etc., and may seriously affect its application field. Large-screen TFT-LCDs are currently mostly used in high-end fields that have strict requirements on viewing angles, such as aerospace, medical, and graphics and image processing. [0003] Existing conventional liquid crystal display devices have a stacked structure in a certain order, such as figure 1 As shown, the existing liquid crystal display device comprises an u...

However, with the expansion of the perspective, it also brings the difficulty of protecting personal privacy.

[0005] The anti-spy film developed by related companies in the industry has achieved better privacy protection, but it can only enable observers with a front view to see the information displayed on the screen, and it cannot be seen clearly at an angle that deviates from the front view. Information displayed on the screen

Therefore, this structure cannot achieve the protection of any viewing angle, for example, it cannot achieve the privacy protection of the positive viewing angle.

[0006] When the user needs to browse the display screen at certain specific angles and clearly obtain the content displayed on the display device, and does not want people in other viewing angles to also see the content on the display screen, the prior art is far from cannot meet the needs of observers
