Description

Intelligent blackboard adopting zero laminating technology

Technical Field

The utility model belongs to the technical field of the wisdom blackboard, especially, relate to a wisdom blackboard of zero laminating technique.

Background

Existing touch screens can be generally classified into: resistance type, capacitance type, infrared, surface acoustic wave, electromagnetism, pressure sensing and the like, and the application of the resistance type and the capacitance type touch screens is the most extensive at present.

The interface circuit of the resistive touch screen mainly comprises a serial port data circuit and a USB data interface circuit, and generally comprises four-wire system, five-wire system and the like. The screen body part of the resistance touch screen is a multilayer composite film, two transparent conductive layers ITO are covered between a surface protective coating and a base layer of the four-wire resistance touch screen, the two layers respectively correspond to an x axis and a Y axis, the two layers are insulated by fine transparent insulating particles, the two conductive layers are connected by pressure generated during touch, and the x and Y coordinates of touch are obtained due to the change of resistance values. The transparent conductive layer ITO which applies voltage fields in the x and Y directions to the same layer and the nickel-gold conductive layer on the outermost layer are covered on the base layer of the five-wire resistance touch screen and used as pure conductors.

The current wisdom blackboard is mostly the frame subsides, laminates all around, and the centre is unsettled. The touch screen is easily affected by factors such as temperature and external force, deformation is caused, touch sensitivity is affected, and touch function failure is seriously and directly caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a zero wisdom blackboard of laminating technique through between touch TP membrane and liquid crystal glazing, increases the mode of shielding layer, plays electromagnetic shield and anti-deformation effect, and the frame is installed to the side of this application in addition, plays the guard action, is equipped with the through-hole in the frame simultaneously, and the wire of being convenient for is regular, has solved the relevant problem that proposes in the background art.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a zero wisdom blackboard of laminating technique, which comprises a plate body, the plate body mainly comprises toughened glass, touch TP membrane, shielding layer and the liquid crystal glazing of a laminating, the side of plate body bonds and has the frame, be equipped with the bead on frame and toughened glass and liquid crystal glazing's the contact surface.

Further, the shielding layer includes but is not limited to PMMA, PC, PE film, PP film, special composite film material.

Further, the thickness of the shielding layer is in the range of 0.5mm-4.0 mm.

Further, the frame is a rubber strip.

Furthermore, a through hole is formed in the frame in a penetrating mode, and a lead is placed in the through hole.
