Problems solved by technology

[0003] At present, the electronic blackboard produced by Metal Mesh Sensor (also known as Projective Capacitive Touch Foil) in China must leave a gap of not less than 4mm between the touch film substrate and the display panel. More cutting-edge companies can only control this gap to more than 2mm, otherwise there will be a problem of touch failure

Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The structure of the metal mesh sensor (projected capacitive touch film) is as follows figure 1 shown. figure 1 The pattern in the middle touch area is a metal mesh sensor, the horizontal is the sending line, the vertical is the receiving line, and the outside is the sending and receiving flick lead.

[0038] According to the structure of the touch area and the sending and receiving leads (flicking), from the perspective of the circuit, there are self-...

Abstract

The invention discloses a method for realizing full bonding of a metal mesh touch film electronic blackboard, which comprises the following steps of: a stable self-capacitance is formed by adding an isolation ground wire between a receiving tail-flick lead and a transmitting tail-flick lead and outside the receiving tail-flick lead to form an initial stable self-capacitance; adding power filter: adding single-phase three-section power filter to the power input port of the electronic blackboard; sensitivity debugging: setting the appropriate touch sensitivity with EasyTune software. A stabilizeself-capacitor, increase power filter and sensitivity debugging process, The invention effectively solves the problem that the electronic blackboard of the existing metal mesh sensor can not realizefull bonding, and makes the touch control film substrate of the electronic blackboard and the display panel realize stable and effective touch control under the condition of full bonding, and the clarity and brightness of the display image are greatly improved, and the viewing angle reaches more than 160 degrees.

Description

technical field [0001] The invention belongs to the field of electronic blackboards, and relates to a method for fully laminating an electronic blackboard with a metal mesh touch film using electronic touch anti-interference technology. Background technique [0002] The development of educational informatization has brought about major changes in educational forms and learning methods, and promoted educational reform.
