Abstract

The invention provides a display device for realizing the elimination of the black border phenomenon in splicing, which includes a display module, and the display module includes a display area and a black border area; The polarized output light corresponding to the coverage area is formed as the output light with both the first and second polarization directions; the half mirror arranged on the beam splitter, the half mirror covers the area where the beam splitter is located above the display area, and Part of the outgoing light formed by the beam splitter is directly transmitted along the first polarization direction above the entire area of ​​the half-mirror for display, and part of the outgoing light is reflected along the second polarization direction parallel to the black frame area; and arranged in the black frame The reflecting mirror on the area, the reflecting mirror further reflects the emitted light to be displayed above the entire area of ​​the black border area, so as to visually eliminate the black border area. The implementation of the present invention can eliminate the black border phenomenon after splicing different liquid crystal displays and improve the visual impact.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display device for realizing the elimination of black border phenomenon in splicing. Background technique [0002] Liquid crystal display is the mainstream display device today, but due to the limitation of the product structure principle, there will be a black border around it. The black border is mainly formed by the frame glue sealing the liquid crystal and the circuit for inputting the source signal or gate signal. Of course, when the display module is finally assembled, the thickness of the structural frame is also included. With the improvement of technology, the black frame of the liquid crystal display can be gradually reduced to 5mm or even smaller, but it cannot be completely eliminated. Especially under the requirements of frameless design, high-resolution design and other specifications, it is very difficult to reduce the size of the black frame. ...
