Problems solved by technology

In particular, the glass of the display module panel will bulge due to thermal expansion, which shortens the distance between the two panels and reduces the touch performance. In severe cases, the touch will not be possible at all.

Abstract

The invention discloses a convex touch glass large-screen LCD display module and an electronic blackboard. The convex touch glass large-screen LCD display module comprises a straight display module body, a glass substrate and a profile outer frame, wherein a projection type capacitive touch film is adhered to the glass substrate in a relatively convex manner, and the profile outer frame is used for fixing the display module body and the touch film glass substrate. According to the convex touch glass large-screen LCD display module, by setting the convex touch film glass substrate, and by setting the touch film glass substrate and the display module body in the same sectional material outer frame together, a certain distance is formed between the touch film glass substrate and the local area of the central position of the display module body; and in this way, during the using process of the display module body, the liquid crystal panel glass on the display module body does not make contact with the touch control film glass substrate when protruding outwards in the direction of the touch control film glass substrate, so that the problems of touch control failure, water vapor condensation, pattern pressing, convection heat dissipation and the like caused by protruding outwards of the liquid crystal panel glass are practically solved, and stable touch control, clear display and smooth writing of common chalks are achieved.

Description

technical field [0001] The invention relates to the technical field of touch control of a large-screen LCD display module, in particular to a large-screen LCD display module and an electronic blackboard with convex touch glass. Background technique [0002] With the advancement of modern conferences, teaching and communications, large-screen display and touch control technologies have been more and more widely used in various industries, especially in the field of education, such as electronic blackboards. The electronic blackboard consists of a central main board with display, touch and writing functions and two side sub-boards with writing and device setting functions. Due to functional and structural reasons, the two sides of this type of electronic blackboard cannot form infrared radiation, so the traditional and mature infrared frame touch technology cannot be applied here, and only the projected capacitive film touch control method can be used. [0003] Projected capa...
