Problems solved by technology

This kind of manufacturing method increases the thickness of the terminal electronic product, and because the sensing of the existing touch technology is limited by the size of the resistance value generated in the intersecting area of ​​the two wires, the size of the capacitance area and the size of the photosensitive area, the touch sensitivity is thus limited. , and the structure is complex and the manufacturing cost is high

other Embodiment approach

[0028] In other embodiments, the number of the support blocks 202c can also be one or two, and the number of the protrusions 206 and the sensors 204c of the protective soft board 205c is set corresponding to the number of the support blocks 202c, so that the protrusions 206 are The sensor area is touched by at least one point of contact, thereby identifying the touch location. If the number of supporting blocks 202c is one, the supporting block 202c is fixed at the central position of the fixed substrate 201c, and interferes with the back of the mirror surface 203c to support the mirror surface 203c, and a sensor 204c is fixed on the observation surface of the mirror surface 203c and At the position corresponding to the support block 202c, a protrusion 206 of the protection soft board 205c abuts against the sensor 204c. If the number of supporting blocks 202c is two, the supporting blocks 202c are fixed on the two diagonals of the fixed substrate 201c or at the center of the t...

Abstract

The invention discloses a touch display device and a display screen thereof. The display device comprises the display screen and a processing unit which is electrically connected with the display screen, wherein the display screen comprises a plurality of pixel units; each pixel unit comprises a fixed substrate, at least one supporting block, a mirror plane and at least one sensor; the mirror plane is semi-transparent, semi-reflecting and deformable; a high-reflecting film is coated on an internal surface of the fixed substrate; the supporting block is fixed on the fixed substrate and pressedagainst the back of the mirror plane to keep a predetermined distance between the fixed substrate and the mirror plane; the sensor is fixed on an observation plane of the mirror plane; a touch objectpresses the mirror plane to make the mirror plane deformed; the sensor senses deformation to generate resistance or voltage variation; and the processing unit determines a touch position according toa resistance or voltage variation value. In the invention, sensing area is increased by arranging the sensor on each pixel unit of the display screen, so the sensitivity of a touch screen is improved.

Description

technical field [0001] The invention relates to a display device and a display screen thereof, in particular to a display device with a touch function and a display screen thereof. Background technique [0002] As a new type of input device for electronic devices, the touch screen makes the human-computer interaction between people and electronic devices more intuitive and brings great convenience to users. Its application fields have spread throughout home appliances, public information, electronic games, Office automation equipment and other fields. Existing touch technologies include resistive, capacitive, optical (eg IR) and electromagnetic, among which resistive and capacitive touch manufacturers are the majority. At present, many touch screen manufacturers realize color display by completing the touch circuit on the glass substrate, then integrating the glass substrate into the display panel, and integrating related circuits and ICs to provide the touch function. Thi...
