Abstract

The invention provides a touch display device and a manufacturing method thereof. Wherein, the touch display device includes a box-to-box touch panel and a display panel. A deformable layer is arranged between the touch panel and the display panel, and the deformable layer can be deformed when the touch panel is under pressure. The side of the touch panel facing the display panel is provided with a plurality of first electrodes; the side of the display panel facing the touch panel is formed with a plurality of second electrodes, and the second electrodes are in one-to-one correspondence with the first electrodes. The two electrodes and the corresponding first electrodes form a pressure-sensing capacitor; wherein, the touch display device also includes a pressure detection module, which is used to detect the capacitance change value of the pressure-sensing capacitor, and determine the touch panel according to the capacitance change value. pressure value. The solution of the present invention can improve the recognition accuracy and stability of pressure detection, and can also improve the light transmittance of the touch display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display device and a manufacturing method thereof. Background technique [0002] At present, the most widely used touch screen is capacitive touch screen. Its structure is to make two pressure electrodes opposite to each other on the array substrate. According to the principle of parallel plate capacitors, when the capacitive touch screen is under pressure, the distance between the two pressure electrodes When a change occurs, the press operation on the screen is determined according to the parameter change of the capacitance. [0003] However, in this existing structure, other signal lines are arranged on the array substrate, so the pressure sensing accuracy is easily interfered by signals. In addition, in the manufacturing process, it is necessary to form the substrate layer of the pressure electrode on the array substrate first. The substrate layer is general...
