Description

Touch panel and touch display panel

The present invention relates to a touch panel and a touch display panel, and more particularly to a touch panel and a touch display panel having grid electrodes and wires interlaced with each other.

In recent years, with the rapid development of touch sensing technology, many consumer electronic products such as mobile phone, GPS navigator system, tablet PC, and laptop PC (laptop PC) ), both of which are equipped with a display panel and a touch panel to simultaneously have a display function and a touch function. Since the conventional touch panel is disposed on the display surface of the display panel, in order to avoid affecting the image displayed by the display panel, the electrode for touch sensing in the conventional touch panel needs to be made of a transparent conductive material such as indium tin oxide (indium). Formed by tin oxide, ITO). Since the resistance value of the transparent conductive material is generally higher than that of the metal conductive material, the use of the transparent conductive material to form the electrode may cause problems such as an excessively high overall resistance value and a reaction speed. Therefore, at present, the related art has also developed a metal mesh intertwined with metal wires instead of a transparent conductive material to form an electrode to improve the reaction speed. In order to avoid the use of a transparent conductive material with a high resistance value to transmit the signal, the touch panel still needs to electrically connect the electrode to the control circuit by using a metal wire with a low resistance value. However, the metal wires for electrically connecting the electrodes are disposed in the light shielding area of the touch panel, and have a certain number, and the metal wires still need to have a certain spacing between them to be electrically insulated from each other, so the shading of the touch panel The size of the zone is limited by the number and distribution width of the metal wires and cannot be further reduced. As a result, the border of the touch display panel corresponding to the peripheral area cannot be reduced, thereby affecting the appearance of the touch display panel.

One of the main purposes of the present invention is to provide a touch panel and a touch display panel to reduce the size of the touch panel and the touch display panel, thereby improving the appearance of the touch display panel.

To achieve the above objective, the present invention provides a touch panel including a substrate and a touch sensing component. The touch sensing component is disposed on the substrate, and the touch sensing component includes a plurality of grid electrodes, a plurality of wires, and an insulating layer. Each of the grid electrodes includes a plurality of grid lines electrically connected to each other. Each of the wires overlaps at least one of the grid electrodes in a vertical projection direction, and a portion of the grid lines of the respective wires and the overlapping grid electrodes are staggered in a vertical projection direction to form at least one staggered position, wherein each of the wires The wires are electrically connected to the corresponding grid electrodes at at least one staggered position for electrically connecting the respective wires to the corresponding grid electrodes. The insulating layer is disposed between the grid electrode and the wire.

To achieve the above objective, the present invention provides a touch display panel comprising a substrate, a touch sensing component, an array substrate, and a display medium layer. The touch sensing component is disposed on the substrate, and the touch sensing component includes a plurality of grid electrodes, a plurality of wires, and an insulating layer. Each of the wires overlaps at least one of the grid electrodes in a vertical projection direction, and a portion of the grid lines of the respective wires and the overlapping grid electrodes are staggered in a vertical projection direction to form at least one staggered position, wherein each of the wires The wires are electrically connected to the corresponding grid electrodes at at least one staggered position for electrically connecting the respective wires to the corresponding grid electrodes. The insulating layer is disposed between the grid electrode and the wire. The array substrate is disposed opposite to the substrate, and the display medium layer is disposed between the array substrate and the substrate.

The touch panel of the present invention uses different conductive pattern layers to form wires and grid electrodes, so that the wires are interlaced with the grid electrodes. Therefore, the three sides of the grid electrode do not need to be provided with wires, so that the frame of the touch panel does not need to be used for shielding the wires, so the frame can be reduced, and even the frame is not required, so that the appearance of the touch panel can be beautified.

Thereby, when the signals induced by the grid electrodes 106 are transmitted to the control elements through the wires 108, the control elements can receive the sensing signals quickly and accurately without excessive load due to excessive coupling capacitance. When the grid electrode 106 senses the position of the touch object in a self-capacitance touch sensing manner, the touch panel 100 can reach the hovering touch, that is, when the touch object has not touched the touch panel 100 When the outer surface is on, the control component can receive the sensing signal to achieve the purpose of the touch.
