Problems solved by technology

[0003] However, most of the electronic products with integrated touch function on the market directly assemble the touch panel and the display panel, and then transmit the touch signal and display signal through their own signal lines, so the electronic products must add additional signal line assembly and The space for soldering and the cost of electronic components required to increase the circuit cannot achieve thinning and reduce assembly costs

[0035] Please refer to figure 1 , which shows a schematic cross-sectional view of a touch display panel according to an embodiment of the present invention. The touch display panel 100 includes a first panel 110 , a first conductive layer 120 , a second panel 130 , a second conductive layer 140 and a gap layer 150 . The first panel 110 has a touch sensing area 111 . The first conductive layer 120 is disposed around the touch sensing area 111 . The second panel 130 is arranged parallel to the first panel 110 , and the second panel 130 has a display area 131 correspondingly located below the touch sensing area 111 . The second conductive layer 140 is disposed around the display area 131 . The gap layer 150 is disposed between the first panel 110 and the second panel 130 , and the gap layer 150 includes a plurality of conductive spacers 152 for electrically connecting the first conductive layer 120 and the second conductive layer 140 .

[0047] Please refer to Figure 4 , which shows a schematic cross-sectional view of a touch display panel according to an embodiment of the present invention. Different from the first embodiment, when the configuration space of the first panel 110 is larger than that of the second panel 130, in this embodiment, the control circuit 160 can be configured on the first panel 110 or connected through a flexible circuit board 166 to the first panel 110. Since the conductive spacer 152 is disposed between the first panel 110 and the second panel 130 and is electrically connected between the first conductive layer 120 and the second conductive layer 140, the control circuit 160 can directly receive the detected signal from the first panel 110. The input touch signal is converted into a corresponding display signal, and the display signal is output to the second panel 130 through the conductive spacer 152 to display a picture. Therefore, the user can perform touch operations through t...

[0050] Please refer to Figure 5 , which is a schematic diagram of a touch display panel according to an embodiment of the present invention. In the above first and second embodiments, the gap layer 150 includes a gap wall 154 surrounding the touch sensing region 111 and supported between the first panel 110 and the second panel 130 to form a plastic frame. Since the conductive spacer 152 and the spacer wall 154 are separated from each other, the spacer wall 154 can be thermosetting glue of insulating material, such as epoxy resin or acrylic resin. The difference between this embodiment and the above-mentioned first and second embodiments is that the above-mentioned conductive spacer 152 is connected with the spacer wall 154 as a whole. At this time, the spacers 154 and the conductive spacers 152 are coated on the surrounding area of ​​the touch display panel 101 with the conductive glue including the directional conductive substance 153 to form the conductive glue frame 156 ...

Abstract

The invention discloses a touch display panel which comprises a first panel, a second panel and a clearance layer, wherein the first panel has a touch sensing area, and is configured in parallel to the second panel; the second panel has a displaying area which is correspondingly positioned below the touch sensing area; the clearance layer is configured between the first panel and the second panel; and the clearance layer has a plurality of conductive clearance parts for electrically connecting the first panel with the second panel.

Description

technical field [0001] The present invention relates to a touch-sensitive display panel, and in particular to a touch-sensitive display panel using internal conductive spacers to receive touch signals or transmit display signals. Background technique [0002] Since the development of touch panel technology, touch panels have occupied a very high market share in consumer electronic products. Currently, there are touch display panels integrated with touch and display functions in the market, which can be used in portable consumer electronic products, such as wireless communication mobile phones, notebook computers, tablet computers, digital cameras and other products. [0003] However, most of the electronic products with integrated touch function on the market directly assemble the touch panel and the display panel, and then transmit the touch signal and display signal through their own signal lines, so the electronic products must add additional signal line assembly and The...
