Embedded touch control display device

Abstract

The invention relates to an embedded touch control display device. The device comprises a display and a touch inductive component, wherein the touch inductive component is attached to the outer side of an outermost layer substrate of the display and comprises electrodes in two directions; the electrodes in the two directions intersect with one another and are formed on the same conductive film layer; the electrodes in a first direction are arranged continuously on the conductive film layer; the electrodes in a second direction are partitioned into a plurality of electrode blocks by taking the electrodes in the first direction as intervals; at a crossing point, two adjacent electrode blocks in the electrodes in the second direction are connected through a conductive bridge; the conductive bridge is isolated from the electrodes in the first direction through an insulating layer; the device is characterized in that: the conductive bridge is a metal strip formed on the outermost layer substrate of the display; and the insulating layer is a metal inorganic compound insulating layer formed on a surface layer in a middle section of the metal strip. The touch inductive component has a firm bridging structure which is difficult to damage at the crossing point, so that the embedded touch control display device has high reliability and long service life.

Description

technical field [0001] The present invention relates to a display device, in particular to an embedded touch display device embedded with a touch sensing component. Background technique [0002] Set the transparent touch screen in front of the screen of the display to form a display touch system. The display touch method that cooperates with the screen display and touch sensing has strong interactivity and has become the mainstream input method for handheld devices and portable devices. , such as Apple, HTC (HTC) and other manufacturers of mobile phones, tablet PCs basically use the display touch mode for input; and in terms of software, whether it is the mobile phone platform Android launched by Google, or the PC operating system launched by Microsoft Windows7 also supports display touch mode. It can be seen that the display touch method and related technologies have very broad application prospects. [0003] In the touch screen, the projected capacitive touch screen can ...

Problems solved by technology

In addition, since the material of the conductive bridge and the electrode in the first direction is an inorganic material, and the block resin pad formed by photosensitive resin is an organic material, the gap between the conductive bridge and the block resin pad, the block resin pad and the The bonding force between the electrodes in the first direction is relatively small, which affects the working stability and service life of the touch panel. For example, when the whole is bent and deformed by force, it is easy to separate at the interface, resulting in electrode failure.

It can be seen that it is difficult to obtain good reliability when the block-shaped resin pad formed by photosensitive resin is used as the bridging structure of the insulating layer when the touch-sensing component is arranged on the outer layer of the embedded touch display device.
