Problems solved by technology

[0003] However, there may be poor processing during the binding process, and there may be poor binding status between the driving circuit and the display panel. For example, the driving circuit and the display panel are completely separated or not completely separated, and completely separated products Can't work normally, but the products that are not completely separated can still be displayed normally. With the prolongation of use time, the binding state will gradually deteriorate, and there will be a slight open circuit until it is completely separated, which will affect the reliability of the product during use.

Abstract

The invention discloses a display device and a binding state detection method, the display device comprises a display panel and a driving element, and the display panel is in binding connection with the driving element; the display panel further comprises at least two force-sensitive material layers, the force-sensitive material layers and the first binding terminals or the second binding terminals are arranged in a staggered mode at intervals, and each force-sensitive material layer is insulated from the adjacent first binding terminal or second binding terminal. The force-sensitive material layer is used for detecting the binding state between the display panel and the driving element, when the binding state between the display panel and the driving element is normal, the force-sensitive material layer is in a compressed state, and when the force-sensitive material layer is pressed to deform, the force-sensitive material layer sends out an electric signal. In this way, the binding state between the display panel and the driving element is judged by detecting the electric signal sent by the force-sensitive material layer, and normal work and reliability of a product are guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and a method for detecting a binding state. Background technique [0002] A display device usually includes a display panel and a drive circuit. During the production process, the drive circuit is usually fixed on the display panel by means of binding. Specifically, the adhesiveness of anisotropic conductive adhesive is used to bind the drive circuit to the display panel. The display panel is further connected to the drive circuit and the circuit in the display panel. [0003] However, there may be poor processing during the bonding process, and the bonding state between the driving circuit and the display panel may be poor. For example, the driving circuit and the display panel may be completely separated or not completely separated, while the completely separated product Products that cannot work properly but are not completely separated can st...
