Problems solved by technology

[0007] However, in order to meet the requirements of a large visual image and a thin, simple, and narrow-side-width design, the existing touch panel display 100 has limited space for arranging the wires 134 .
Thus, trace 134 will be 1 Insufficient resistance increases the resistance value, which leads to the attenuation and delay of the transmission of the sensing signal, which affects the operation sensitivity of the conventional touch device 130
In addition, the number of sensors 132 and wires 134 will be limited accordingly, thereby limiting the touch resolution of the touch device 130

[0066] Figure 2A It is a schematic top view of the touch panel display 200 according to the first embodiment of the present invention, Figure 2B and Figure 2C for Figure 2A Touch panel display along I 2 -I 2 ’Schematic cross-section of the line. Please also refer to Figure 2A and Figure 2B The touch panel display 200 of this embodiment includes a first substrate 210 , a second substrate 220 , a touch device 230 , a display medium 240 and a sealant 250 a. The size of the first substrate 210 is greater than the size of the second substrate 220. Specifically, the width of the second substrate 220 is shorter than the width of the first substrate 210, and the length of the second substrate 220 is substantially the same as the length of the first substrate 210. same. In addition, the sealant 250 a forms a closed space with the two substrates 210 and 220 to seal the display medium 240 therein. In addition, the material of the display medium layer 240 is, for example, a...

[0078] Figure 3A A schematic top view of a touch panel display 300 according to a second embodiment of the present invention is shown, Figure 3B for Figure 3A Touch panel display along I 3 -I 3 ’ Schematic diagram of the cross-section of the line. Please also refer to Figure 3A and Figure 3B , the touch panel display 300 of this embodiment is similar to the touch panel display 200 of the first embodiment, the main difference between the two is: the connecting terminal 236 of this embodiment is located on the short side S of the second substrate 220 3 , that is to say, the trace 234 can be formed by the short side S of the second substrate 220 3 pin out. In other words, if Figure 3BAs shown, in this embodiment, the integrated driving circuit 214 is located between the pixel matrix 212 and the connecting terminal 236 .

[0079] In detail, compared with the driving circuit in the prior art, since the integrated driving circuit 214 of this embodiment is thinner, the...

[0081] Figure 4A A schematic top view of a touch panel display 400 according to a third embodiment of the present invention is shown, Figure 4B for Figure 4A Touch panel display along I 4 -I 4 ’Schematic cross-section of the line. Please also refer to Figure 4A and Figure 4B , the touch panel display 400 of this embodiment is similar to the touch panel display 300 of the second embodiment. The gate driving circuit 214a and at least one integrated source driving circuit 214b. Therefore, the second substrate 202 extends not only in the horizontal direction but also in the vertical direction to respectively cover at least part of the integrated gate driving circuit 214 a and at least part of the integrated source driving circuit 214 b. In this way, the space on the second substrate 202 for arranging the wires 234 will be larger than that in the first and second embodiments, so that the number of wires 234 can be increased, thereby improving the touch resolution of the...

The first substrate comprises a display area and a periphery area. The first substrate further comprises a pixel matrix located in the display area and at least one integrated drive circuit in the periphery area. The integrated drive circuit is electrically connected the pixel matrix. The second substrate is arranged on the first substrate to cover the pixel matrix and the integrated drive circuit. The display media layer is arranged on the pixel matrix and between the first substrate and the second substrate. The touch device is arranged on the second substrate, and comprises a sensor and a cable connected with the sensor. The sensor is arranged above the pixel matrix, and the cable is arranged above at least part of the integrated drive circuit.

Description

technical field [0001] The present invention relates to a display, and in particular to a touch panel display. Background technique [0002] In recent years, with the rapid development of various applications such as information technology, wireless mobile communication and information home appliances, in order to achieve more convenience, smaller size and more humanized, the input devices of many information products have been replaced by traditional keyboards or The mouse and the like are transformed into a touch panel (Touch Panel), which is combined with a display to form a Touch Panel Display (Touch Panel Display). Today's common touch panel designs can be roughly divided into resistive, capacitive, optical, acoustic, and electromagnetic types. [0003] Resistive touch panels mainly use the pressure of a single point to make the originally separated conductive layers contact each other and conduct, so a voltage drop (Voltage Drop) is generated at the conduction point, ...
