Composite glass structure used for liquid crystal display

Abstract

The invention provides a composite glass structure used for a liquid crystal display. A functional layer of the composite glass structure comprises a single-face anti-reflection glass layer (2), a linear polaroid (3), a first lambda phase delay piece (4) and a second lambda phase delay piece (5); one face of the linear polaroid (3) is connected with the single-face anti-reflection glass layer (2), the other face of the linear polaroid (3) is connected with the first lambda phase delay piece (4), one face of the second lambda phase delay piece (5) is attached to the upper surface of a liquid crystal panel (1), and the other face of the second lambda phase delay piece (5) is attached to the other face of the first lambda phase delay piece (4). By means of the composite glass structure used for the liquid crystal display, work links and the manufacturing procedures are reduced while the anti-reflection performance, the electromagnetic shielding performance and heating performance of the liquid crystal display are guaranteed, and meanwhile chroma mura of the liquid crystal display and other display defects are avoided.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and more specifically relates to a composite glass structure for liquid crystal displays. Background technique [0002] Military aircraft cockpits or other liquid crystal display devices used outdoors generally have the requirements of strong light visibility, wide temperature operation and electromagnetic shielding. In the liquid crystal display in the prior art, the reinforcement of the liquid crystal panel mainly adopts such as image 3 shown in the sandwich structure. Its structure is mainly that the upper surface of the liquid crystal panel is bonded with an electromagnetic shielding layer (electromagnetic shielding glass) with an anti-reflection coating through liquid optical glue, and at the same time, a transparent ITO conductive glass is bonded under the liquid crystal panel as a low-temperature heating layer. The upper surface of the electromagnetic shielding layer is p...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: aiming at the deficiencies in the prior art, to provide a simple manufacturing process, which can ensure the anti-reflection performance, electromagnetic shielding performance and heating performance of the liquid crystal display without the need to install the liquid crystal panel. It is removed from the liquid crystal module for reinforcement, thereby reducing the number of work links and manufacturing processes, and at the same time avoiding display defects such as uneven chromaticity (mura) of the liquid crystal display in the prior art when the liquid crystal panel is in use.
