Micron narrow-bezel display device and manufacturing method thereof

Abstract

The invention provides a micron narrow-bezel liquid crystal display device and a manufacturing method thereof. The liquid crystal display device is characterized in that a sealing frame with cohesiveness arranged between an upper film substrate and a lower film substrate enables liquid crystals to form a uniform liquid crystal layer according to the thickness of a spacing structure and then sealsthe liquid crystal layer in the closed space, and the sealing frame is at least composed of two parts of connecting structures with concave-convex inlay; and the spacing structure has cohesiveness andis arranged between the upper film substrate and the lower film substrate, and the two ends of the spacing structure make contact with the inner surfaces of the film substrates and / or the inner surface of a film. According to the invention, the adhesive sealing frame and the adhesive spacing structure are added, the width of the sealing frame adhesive is restrained by the outer side structure andthe inner side structure of the sealing frame, micron-order narrow-bezel display can be achieved, the display device is suitable for rigid and flexible full-screen display requirements, small deformation is generated so that the stability of the display device can be kept, and the design requirements of narrow frames of various equipment with the display device, especially splicing screens and portable equipment, can be met.

Description

technical field [0001] The present invention relates to the field of flat crystal display technology, in particular to a micron narrow frame liquid crystal display device and a manufacturing method thereof. Background technique [0002] With the development of electronic products, the demand for portable mobile devices, flat-panel TVs, and wearable display products has grown rapidly. People have higher and higher requirements on the performance of display products. They hope that the viewing range will be wider, and the ratio of screen display size to bezel, that is, the screen-to-body ratio, will be as large as possible. Therefore, narrow bezel display devices continue to attract the attention of the industry. [0003] Wide bezels tend to make the display panel bulky, making it difficult to incorporate it into the housing of the electronic device. Wide bezels may also require a significant portion of the display panel to be covered by an oversized covering (eg, frame, bord...

AI Technical Summary

Problems solved by technology

Among the improvement schemes of the above-mentioned narrow-edge models, there is no improvement in the width of the sealing frame. The main reason is that the width of the narrow-frame adhesive is difficult to accurately control in the printing process. Goes through a flow process, not easy to form a precise geometric shape

Even if the geometric size of the narrow frame is precisely controlled, the insufficient bonding performance of the too small frame size will easily lead to peeling off and loss of bonding performance

The narrow bezel process in the prior art cannot achieve micron level sealing, especially for narrow bezel liquid crystal display devices below 500 microns
