Touch panel and display device thereof

Abstract

The invention discloses a touch panel and a display device thereof. The touch panel comprises a mounting frame, a cover plate is arranged on the upper side of the mounting frame, a heat conducting plate is fixedly connected to the lower side in the mounting frame, the upper side of the heat conduction plate is fixedly connected with a heat dissipation plate, a light guide plate is arranged on theupper side of the heat dissipation plate, a diffusion sheet is arranged on the upper side of the light guide plate, a touch panel is arranged on the upper side of the diffusion sheet, flexible circuitboards are arranged at the positions, located at the side ends of the light guide plate, of the two sides of the heat dissipation plate, and light sources are fixedly connected to the side ends of the flexible circuit boards. The invention can increase the sealing performance, avoid light leakage, and facilitate installation and disassembly.

Description

technical field [0001] The invention relates to the field of touch panels, in particular to a touch panel and a display device thereof. Background technique [0002] The touch panel is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connected devices according to the pre-selected program. Most of the current touch panels are fixed with screws. It is not easy to control the strength of the screws when they are turned, and it is easy to cause excessive pressure and damage the display screen; and every disassembly will cause damage to the threaded holes, resulting in the touch panel. Inadequate encapsulation with the frame creates a gap, which causes light to emit from the edge of the touch panel, resulting in light leakage and affecting the user experience. Contents of the invention [0003] The purpose of the present in...
