Embodiment Construction
[0030] 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 creative efforts fall within the protection scope of the present invention.
[0031] Display devices such as Micro LED (Light-Emitting Diode, abbreviated as Micro LED) microdisplays and organic electroluminescent displays (Organic Electro luminesecent Display, OLED) are self-luminous display terminals that do not require a backlight source, have a wide range of viewing angles, and are thinner. Thin, which involves multidisciplinary research fields such as physics, chemistry, materials science and electronics, has the advantages of high bright...

The invention discloses a pressure sensing device, a display panel, a manufacturing method thereof, and a display device, and relates to the field of display technology, so that the pressure sensing device can be integrated in the display panel, thereby preventing the pressure sensing device from being installed on the frame of the display device. Improve the pressure sensing accuracy of the pressure sensing device. The pressure sensing device includes a ring-shaped electrode assembly and a columnar electrode assembly arranged in the ring-shaped electrode assembly, the ring-shaped electrode assembly and the columnar electrode assembly are insulated from each other, and the ring-shaped electrode assembly and / or the columnar electrode assembly The annular electrode assembly and the columnar electrode assembly move relative to each other under the force of the axial direction of the electrode assembly, and the ring electrode assembly and the columnar electrode assembly form a coupling capacitor, and the coupling capacitance changes during relative movement. The display panel includes the pressure sensing device mentioned in the above technical solution. The pressure sensing device provided by the invention is used in display.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a pressure sensing device, a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, touch display devices have been popularized in people's daily life, bringing great convenience to people's daily life. [0003] In order to increase the human-computer interaction performance of the touch display device, a pressure sensing device based on pressure sensing technology is added to the frame of the existing touch display device, so that the pressure sensing device can sense the pressure exerted by the user on the touch display device, and The pressure signal is converted into an electrical signal and transmitted to the processor for processing, thereby controlling the touch display device to perform required operations. However, since the assembly tolerance of the frame of the pressure sensing de...
