Problems solved by technology

However, the use of jumper connections will increase the wiring space-and reduce the space for pixel penetration in the structure, thereby reducing the aperture ratio of the panel, and will also increase the number of photomask layers required for manufacturing the panel, thereby improving the panel. manufacturing cost

Embodiment Construction

[0027] Please refer to figure 1 , figure 1 It is a schematic diagram of a touch display device 10 according to an embodiment of the present invention. The touch display device 10 can be an electronic product with a touch display panel such as a smart mobile phone, a tablet calculator, etc., and is not limited thereto. Such as figure 1 As shown, the touch display device 10 includes a panel 100 and a driving chip 102 . The panel 100 includes a display area and a non-display area, wherein the display area is provided with display elements (such as a pixel array (not shown in figure 1 )) and a plurality of sensing electrodes E1-E12 disposed on a touch electrode layer. The sensing electrodes E1 - E12 are used to sense the capacitance variation to generate information for judging whether the touch display device 10 is touched by an external object and the touched position. In one embodiment, the touch electrode layer is a conductive layer used to provide a common voltage in the...

Abstract

A touch display device includes a display area and a non-display area and further includes a touch electrode layer; wherein a plurality of sensing electrodes is configured in the electrode layer; wherein each sensing electrode extends from the display area to the non-display area and is coupled to a driver chip via a connection structure; wherein the connection structure locates in the non-displayarea.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a low cost and high aperture ratio touch display device. Background technique [0002] With the development of touch sensing technology, convenient and practical touch devices are widely used in various products such as mobile phones, global positioning navigation systems, tablet calculators, personal digital assistants, and notebook calculators. [0003] As time goes on, panel manufacturers continue to develop touch panels that are thinner and more precise. In recent years, touch panels with an in-cell structure have become popular. By setting the sensing components in the display architecture of the panel, the number of layers to realize the embedded architecture can be reduced by one. Accordingly, the visible distance between the user's finger and the user's actual touch point on the display panel is reduced, so that the user can click on the displayed content more intuitive...
