Description
本發明是有關於一種顯示面板，且特別是有關於一種觸控顯示面板。The present invention relates to a display panel, and in particular to a touch display panel.
以觸控部分的位置來區分，觸控顯示面板可分為外貼式（out-cell）、整合式（on-cell）及內嵌式（in-cell）。其中，內嵌式觸控顯示面板具有厚度薄的優勢，而廣為高階電子產品所使用。According to the position of the touch part, touch display panels can be divided into out-cell, on-cell, and in-cell. Among them, the in-cell touch display panel has the advantage of being thin, and is widely used in high-end electronic products.
內嵌式觸控顯示面板的顯示部分可包括多個共用電極。所述多個共用電極分為多群，且在觸控感測時段可做為多個觸控電極使用。以自容式的內嵌式觸控裝置為例，一般而言，部分製造商將多個觸控電極分別透過多條觸控訊號線電性連接至集成電路（例如：晶片）以及多個觸控開關（例如：薄膜電晶體）。然而，為使觸控電極能被觸控開關良好地充電，觸控開關需具有相當的尺寸及數量，無法進一步縮小邊框，不利內嵌式觸控顯示面板的視效。The display portion of the in-cell touch display panel may include a plurality of common electrodes. The plurality of common electrodes are divided into a plurality of groups, and can be used as a plurality of touch electrodes during a touch sensing period. Taking a self-contained embedded touch device as an example, in general, some manufacturers electrically connect multiple touch electrodes to an integrated circuit (such as a chip) and multiple touch electrodes through multiple touch signal lines, respectively. Control switch (for example: thin film transistor). However, in order for the touch electrodes to be well charged by the touch switches, the touch switches need to have a considerable size and quantity, and the frame cannot be further reduced, which is disadvantageous for the visual effect of the embedded touch display panel.
此外，因為電阻電容負載效應（RC loading effect）的影響，靠近集成電路的共用電極與遠離集成電路的共用電極的電壓恢復能力不同，導致色差產生，降低內嵌式觸控顯示面板的顯示品質。In addition, due to the influence of the RC loading effect, the voltage recovery capability of the common electrode near the integrated circuit and the common electrode far from the integrated circuit are different, which results in color difference and reduces the display quality of the in-cell touch display panel.

Under the above settings, only some of the touch electrodes are electrically connected to the touch switch. In this way, the number and space of touch switches required can be reduced, and the frame can be further reduced, thereby improving the visual effect and the display quality of the touch display panel. In addition, the first touch electrode can be electrically connected to the touch switch to improve the voltage recovery capability to a voltage recovery capability similar to that of the second touch electrode. In this way, the influence of the resistance-capacitor load effect can be reduced, the occurrence of chromatic aberration can be reduced, and the display quality of the touch display panel can be improved.

With respect to the second touch electrode group 320, the first touch electrode group 310 is adjacent to the touch switch 200. The long axis of the second touch electrode group 320 in the second partition 16 is parallel to the short side 12A, and the second touch electrode group 320 is arranged in multiple rows along the direction in which the short side 12A extends, but the present invention is not limited thereto. .

Each first touch signal line TL1 can electrically connect each touch electrode 312 to the touch switch 200 and the integrated circuit 120. For example, the first touch signal line TL1 includes a first section 410 and a second section 420. The first segment 410 may electrically connect the touch switch 200 to the first touch electrode 312 in the first touch electrode group 310. The second section 420 may electrically connect the first touch electrode 312 to the integrated circuit 120. In this embodiment, each second touch signal line TL2 can electrically connect each second touch electrode 322 to the integrated circuit 120. In some embodiments, the first touch signal line TL1 further includes a third segment 430. The third segment 430 electrically connects the first segment 410 to the first touch electrode 312. In this embodiment, the first section 410 and the third section 430 are, for example, an integrated structure, but the present invention is not limited thereto. In the manufacturing process, the third section 430 and the first section 410 can also be formed by the same or different process steps, and the present invention is not limited thereto.
在上述的設置下，第一觸控電極組310中的多個第一觸控電極312分別電性連接至對應的觸控開關200（例如：圖1A繪示第一觸控電極312電性連接至觸控開關組220中的觸控開關200）及集成電路120。第二觸控電極組320中的多的第二觸控電極322分別直接電性連接至對應的集成電路120。如此，僅部分的觸控電極組300，例如第一觸控電極組310，可以電性連接至觸控開關200及集成電路120。因此，觸控顯示面板10可以減少所需觸控開關200的數量，降低觸控開關200所佔的空間，進一步縮小邊框，進而改善視覺效果，提升觸控顯示面板10的顯示品質。Under the above setting, the plurality of first touch electrodes 312 in the first touch electrode group 310 are electrically connected to the corresponding touch switches 200 (for example, FIG. 1A illustrates the first touch electrodes 312 electrically connected. To the touch switch 200 in the touch switch group 220) and the integrated circuit 120. A plurality of second touch electrodes 322 in the second touch electrode group 320 are directly and electrically connected to the corresponding integrated circuits 120 respectively. In this way, only a part of the touch electrode group 300, such as the first touch electrode group 310, can be electrically connected to the touch switch 200 and the integrated circuit 120. Therefore, the touch display panel 10 can reduce the number of touch switches 200 required, reduce the space occupied by the touch switches 200, further reduce the frame, thereby improving the visual effect and the display quality of the touch display panel 10.
此外，由於第一分區14中的第一觸控電極組310鄰近觸控開關組220而遠離集成電路120，第二分區16中的第二觸控電極組320鄰近集成電路120，且第一觸控電極組310中的第一觸控電極312電性連接至鄰近的觸控開關200，因此觸控開關200可以提供預定的電壓至第一觸控電極312。如此，觸控開關200可以彌補第一觸控電極312因電阻電容負載效應所降低的電壓恢復能力。換句話說，遠離集成電路120的第一觸控電極312，可透過觸控開關200提升電壓恢復能力至類似於鄰近集成電路120的第二觸控電極組322的電壓恢復能力。在上述的設置下，觸控開關200可以降低電阻電容負載效應對觸控電極TE的影響，減少色差產生，提升觸控顯示面板10的顯示品質。In addition, since the first touch electrode group 310 in the first partition 14 is adjacent to the touch switch group 220 and away from the integrated circuit 120, the second touch electrode group 320 in the second partition 16 is adjacent to the integrated circuit 120, and the first touch The first touch electrode 312 in the control electrode group 310 is electrically connected to the adjacent touch switch 200, so the touch switch 200 can provide a predetermined voltage to the first touch electrode 312. In this way, the touch switch 200 can make up for the voltage recovery capability of the first touch electrode 312 due to the resistance and capacitance load effect. In other words, the first touch electrode 312 far from the integrated circuit 120 can improve the voltage recovery capability to the voltage recovery capability of the second touch electrode group 322 adjacent to the integrated circuit 120 through the touch switch 200. Under the above-mentioned settings, the touch switch 200 can reduce the effect of the resistance and capacitance load effect on the touch electrode TE, reduce the occurrence of color difference, and improve the display quality of the touch display panel 10.
簡言之，由於第一觸控電極312鄰近觸控開關200且透過第一觸控訊號線TL1電性連接至對應的觸控開關200及集成電路120，第二觸控電極322鄰近集成電路120且透過第二觸控訊號線TL2直接電性連接至集成電路120。在上述的設置下，僅第一觸控電極組310中的第一觸控電極312電性連接至觸控開關200。如此，可以減少所需觸控開關200的數量及空間，進一步縮小邊框，進而改善視覺效果，提升觸控顯示面板10的顯示品質。此外，鄰近觸控開關200而遠離集成電路120的第一觸控電極312，可透過電性連接至觸控開關200，以提升電壓恢復能力至類似於鄰近集成電路120的第二觸控電極322的電壓恢復能力。在上述的設置下，觸控開關200可以降低電阻電容負載效應對觸控電極TE的影響，減少色差產生，提升觸控顯示面板10的顯示品質。In short, since the first touch electrode 312 is adjacent to the touch switch 200 and is electrically connected to the corresponding touch switch 200 and the integrated circuit 120 through the first touch signal line TL1, the second touch electrode 322 is adjacent to the integrated circuit 120. The second touch signal line TL2 is directly electrically connected to the integrated circuit 120. Under the above setting, only the first touch electrode 312 in the first touch electrode group 310 is electrically connected to the touch switch 200. In this way, the number and space of the touch switches 200 required can be reduced, and the frame can be further reduced, thereby improving the visual effect and improving the display quality of the touch display panel 10. In addition, the first touch electrode 312 adjacent to the touch switch 200 and far away from the integrated circuit 120 can be electrically connected to the touch switch 200 to improve the voltage recovery capability to the second touch electrode 322 similar to the adjacent integrated circuit 120. Voltage recovery capability. Under the above-mentioned settings, the touch switch 200 can reduce the effect of the resistance and capacitance load effect on the touch electrode TE, reduce the occurrence of color difference, and improve the display quality of the touch display panel 10.

Chromatic aberration occurs, which improves the display quality of the touch display panel 10A.

綜上所述，本發明一實施例的觸控顯示面板，由於第一觸控電極可透過第一觸控訊號線電性連接至對應的觸控開關及集成電路，第二觸控電極可透過第二觸控訊號線直接電性連接至集成電路。在上述的設置下，僅部份的觸控電極電性連接至觸控開關。如此，可以減少所需觸控開關的數量及空間，進一步縮小邊框，進而改善視覺效果，提升觸控顯示面板的顯示品質。此外，第一觸控電極可透過電性連接至觸控開關，以提升電壓恢復能力至類似於第二觸控電極的電壓恢復能力。另外，第一觸控訊號線的寬度更可以大於第二觸控訊號線的寬度，以提升連接第一觸控電極至觸控開關的訊號線段的線寬。在上述的設置下，觸控開關可以降低電阻電容負載效應對觸控電極的影響，減少色差產生，提升觸控顯示面板的顯示品質。In summary, in the touch display panel according to an embodiment of the present invention, since the first touch electrode can be electrically connected to the corresponding touch switch and integrated circuit through the first touch signal line, the second touch electrode can be transmitted through The second touch signal line is directly electrically connected to the integrated circuit. Under the above settings, only some of the touch electrodes are electrically connected to the touch switch. In this way, the number and space of touch switches required can be reduced, and the frame can be further reduced, thereby improving the visual effect and the display quality of the touch display panel. In addition, the first touch electrode can be electrically connected to the touch switch to improve the voltage recovery capability to a voltage recovery capability similar to that of the second touch electrode. In addition, the width of the first touch signal line can be larger than the width of the second touch signal line, so as to increase the line width of the signal line segment connecting the first touch electrode to the touch switch. Under the above-mentioned settings, the touch switch can reduce the impact of the resistance and capacitance load effect on the touch electrodes, reduce the occurrence of color difference, and improve the display quality of the touch display panel.
