Problems solved by technology

At present, the strain gauges in the resistive pressure display panel are arranged under the backlight layer of the display panel or at the surrounding frame of the display panel. When the strain gauges are arranged under the backlight layer of the display panel, the thickness of the entire display panel will be increased, which is not conducive to The thinning of the display panel, and because the strain gauge is placed under the backlight layer, the sensitivity of the finger touch will be greatly weakened, reducing the touch sensitivity
When the strain gauge is arranged around the frame of the display panel, since the frame of the display panel is mainly attached by double-sided tape, there will inevitably be a gap between the double-sided tape and the display panel, which will greatly reduce the pressure caused by the pressure applied to the surface of the display panel. Deformation, which reduces the precision of Force Touch

Embodiment Construction

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0029] image 3 It is a schematic diagram of distribution of electric bridges in strain gauges in the prior art. Such as image 3 As shown, the existing bridges are all fabricated on the same layer. The bridge requires R1 and R2 (R3 and R4) to feel different deformations. For example, R1 (R3) feels compression deformation, and R2 (R4) feels tension deformation. In practice, R1 and R2 (R3 and R4) must be spatially separated...

Abstract

The invention provides a display panel. The display panel comprises a first substrate; a second substrate, which is opposite to the first substrate; and at least one group of pressure sensing modules, wherein the pressure sensing modules comprise a plurality of pressure sensing units, and the pressure sensing units comprise at least two pressure-sensitive resistors located at different plane layers. The display panel provided by the invention can detect the pressing strength when realizing detection of a touch position, that is, the display panel provided by the invention can be integrated with display, touch and pressure touch, and can effectively reduce the bridge size and avoid the influence on a detection result due to the uneven temperature between the pressure sensing units.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel that simultaneously realizes pressure touch in a capacitive display panel. Background technique [0002] As an input medium, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. Integrating a touch function on a display device has become a research and development hotspot of more and more flat panel display manufacturers. [0003] figure 1 It is a schematic structural diagram of a typical mutual capacitance display panel in the prior art. Such as figure 1 As shown, the display panel 10A includes a plurality of scanning lines 122 extending along the X direction and a plurality of data lines 124 extending along the Y direction, and a plurality of drive electrode blocks 101 arranged in an array along the X direction and the Y direction and a plurality of driving electrode blocks 101 along the Y directi...
