Abstract

The present invention relates to the technical field of electronic devices, in particular to a touch display device, which includes a flexible display panel and several electrodes; the flexible display panel includes a base layer, an encapsulation layer, and several retaining walls, and the base layer has several retaining wall setting areas , the setting area of ​​the barrier wall is located in the non-display area of ​​the touch display device; the barrier wall is encapsulated between the base layer and the encapsulation layer, and in the thickness direction of the touch display device, the The projection of the barrier wall to the base layer falls into the setting area of ​​the barrier wall; the electrodes are used to detect the deformation of the touch display device, and in the thickness direction of the touch display device, the electrodes The projection of the base layer falls into the setting area of ​​the retaining wall. The structure of the touch display device is simpler and the cost is lower, and this structure can be better used in a light and bendable flexible display.

Description

technical field [0001] The present invention relates to the technical field of electronic devices, in particular to a touch display device. Background technique [0002] For touch display devices, touch operation is a relatively important human-computer interaction operation, so accurately detecting relevant parameters of touch operations is one of the important means to ensure user experience of touch display devices. [0003] In the traditional technology, components such as sensor film or pressure-sensitive coil need to be added to the touch display device to realize the detection of the touch operation. flaws in lightweight, bendable flexible displays. Contents of the invention [0004] The invention provides a touch display device to simplify the structure of the touch display device. [0005] The touch display device provided by the present invention includes a flexible display panel and a plurality of electrodes; [0006] The flexible display panel includes a bas...
