Problems solved by technology

It is precisely because of the large spacing that it is easy to see light leakage at large viewing angles
In addition, with the narrow bezel design trend of products, the layout space of the black matrix is ​​also reduced simultaneously, which will cause the black matrix to be too narrow to effectively block the light source projected from the lower backlight, resulting in light leakage

Abstract

The invention provides an advanced hyper view angle display for reducing leakage of light. The advanced hyper view angle display comprises a colored optical filter glass substrate, a thin film transistor array substrate, a black matrix and a sealant, wherein the sealant is used for enabling the colored optical filter glass substrate to be adhered to the thin film transistor array substrate; the black matrix is arranged on the colored optical filter glass substrate, and extends to a cutting line of the colored optical filter glass substrate at least. Compared with the prior art, the black matrix of the advanced hyper view angle display provided by the invention extends to the cutting line of the colored optical filter glass substrate, so that light projected by a backlight on the lower side can be shielded more effectively, and the leakage of light is reduced. In addition, the black matrix is cut off because of being provided with an opening part in the path, which avoids the phenomenon that a black screen with conductivity is greenish. Moreover, an additive special process are not needed, so that the process cost is not increased.

Description

Technical field [0001] The invention relates to a liquid crystal display, in particular to a high-definition display with a super-large viewing angle for reducing light leakage. Background technique [0002] In recent years, Advanced Hyper View Angle (AHVA) displays have adopted In Plane Switching (IPS) liquid crystal technology, and the touch panel packaging method is to directly form touch sensors on tempered glass. The method is more advanced than the traditional IPS packaging method. In this way, the LCD screen can be made thinner, and the touch sensitivity and accuracy are higher. [0003] In existing AHVA display products, the distance between the upper iron frame and the glass is 0.3 micrometers to prevent the upper iron frame from touching the glass and causing an undesirable situation like mura. This design specification is much larger than the 0.1 micron of the Twisted Nematic (TN) model. It is precisely because the spacing is too large that it is easy to see light leak...
