Abstract

The invention discloses a pressure touch structure and a display device. The pressure touch structure comprises a pressure sensor and a reference layer, wherein capacitance is formed between the pressure sensor and the reference layer; the pressure sensor comprises a first pattern layer and a second pattern layer, and the second pattern layer comprises a cooling structure. In the pressure touch structure, the cooling structure is arranged in the pressure sensor, cooling fins do not need to be independently arranged except the pressure sensor, the problem of poor pressure touch effect caused bythe unevenness of the cooling fin is avoided, and therefore, a pressure touch effect is improved. Since the cooling fins do not need to be independently arranged except the pressure sensor, a fittingtechnology that the cooling fins are independently arranged is omitted, and material cost is lowered.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a pressure touch control structure and a display device. Background technique [0002] With the development of touch technology, capacitive force touch technology is increasingly used in display devices. For the display device provided with the capacitive pressure touch structure, different control functions can be triggered by different touch force. [0003] The capacitive pressure touch structure in the prior art may include a force sensor and a reference layer, the reference layer is grounded, an isolation layer is disposed between the pressure sensor and the reference layer, and the force sensor and the reference layer form a capacitor. [0004] The capacitive pressure touch structure also includes a Cu heat sink for heat dissipation. The Cu heat sink is a separate structure in the capacitive pressure touch structure. Due to the unevenness of the Cu heat sink...
