Problems solved by technology

[0004] The concave large-screen LCD display module provided by the present invention will solve the convexity of the display module panel glass caused by factors such as temperature and humidity of the large-screen LCD display module panel glass, shorten the display module panel glass and the touch film glass substrate The distance between the two boards increases the capacitance between the two boards, causing the problem of touch failure or even touch failure. At the same time, it also solves the problem of display, touch and touch caused by the distance and roughness of the existing electronic blackboards. The problem of balance between chalk writing performance, providing a concave LCD touch display module and a touch display blackboard

Abstract

The invention discloses a concave LCD touch display module and a touch display blackboard. The concave LCD touch display module is used for a graphical display function, and comprises a display modulebody and an opposite touch film glass substrate, the display module body is recessed in the direction away from the touch film glass substrate, a certain distance is kept between the display module body and the touch film glass substrate, and the outer frame is used for installing the display module body and the touch film glass substrate on the inner wall of the outer frame. According to the invention, the display module body is concave inwards through the related fixing pieces, the problem that touch control fails due to the fact that panel glass on the display module body protrudes outwards easily in a conventional mounting and fixing mode can be practically solved, and stable and effective touch control and smooth common chalk or fountain pen writing are achieved.

Description

technical field [0001] The invention relates to the technical field of concave touch control of large-screen LCD display modules, in particular to a concave LCD touch display module and a touch display blackboard. Background technique [0002] With the advancement of modern conferences, teaching and communication, large-screen display and touch control technologies are more and more widely used in all walks of life, especially in the field of education, such as electronic blackboards; electronic blackboards are composed of display, touch and writing functions. It consists of the middle main board and the 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 capacitiv...
