Abstract

The invention provides a touch-control display device. The touch-control display device comprises a touch panel, a liquid crystal display module and UV (Ultraviolet) gel, wherein the touch panel comprises a touch screen and black matrices positioned on two sides of the touch screen; the liquid crystal display module is provided with frame gums wrapping the periphery of the liquid crystal display module; the UV gel is positioned between the touch panel and the liquid crystal display module and cured by external UV light; a first reflective layer is arranged on the lower surface of one black matrix; and a second reflective layer is arranged on the upper surface of one of the frame gums of the liquid crystal display module. The UV light propagation distance is prolonged through multiple reflection between the two reflective layers so as to improve the UV glue curing depth and further enable the UV gel to be cured more soundly, so that the touch panel and the liquid crystal display module can be bonded more firmly.

Description

technical field [0001] The present invention relates to a display device, in particular to a touch display device capable of increasing the curing depth of UV (Ultraviolet, ultraviolet light) glue. Background technique [0002] Currently, existing touch display devices mainly include a touch panel and a liquid crystal display module. The liquid crystal display module is located under the touch panel, and when the touch panel is touched by a human finger or a stylus, the corresponding image is displayed by the liquid crystal display module. In addition, in the touch display device, the touch panel and the liquid crystal display module are often bonded by sticky adhesives such as double-sided tapes and adhesive materials. Usually, an external accessory structure is required to confirm that the relative position of the touch panel and the LCD module is correct before bonding, so that the touch panel and the LCD module can be positioned reliably and avoid the adhesion between t...
