Detailed Description
The following describes in detail a specific implementation of a touch display panel and a display device according to embodiments of the present invention with reference to the accompanying drawings.
The shape and size of each film layer in the drawings do not reflect the actual proportion thereof in the touch display panel, and the purpose is to illustrate the invention only.
As shown in fig. 1 and fig. 2, the touch display panel provided in the embodiment of the invention includes an upper substrate 101 and a lower substrate 102 opposite to each other, a black matrix layer 103 disposed on a side of the upper substrate 101 facing the lower substrate 102, and a shielding electrode 104 disposed between the upper substrate 101 and the black matrix layer 103, where the shielding electrode 104 is at least disposed in a region where a pattern of the black matrix layer 103 is located.
In the touch display panel provided by the embodiment of the invention, the display signal loaded in the liquid crystal screen with the black matrix layer 103 can be shielded by using the shielding electrode 104 arranged between the upper substrate 101 and the black matrix layer 103, so that the interference of the display signal on the touch signal loaded in the touch screen is avoided, and the touch accuracy is improved. Meanwhile, the shielding electrode 104 is arranged at least in the region where the pattern of the black matrix layer 103 is located, so that the influence of the shielding electrode 104 on the pixel aperture ratio in the liquid crystal screen is avoided. In addition, light emitted from the backlight in the liquid crystal panel is blocked by the black matrix layer 103 and does not interfere with the shielding electrode 104, so that no optical moire is generated, and a good optical effect can be achieved.
It should be noted that, at present, many common touch display panels are all equipped with an active stylus, when the active stylus slides on the touch display panel, the active stylus emits a signal, a touch electrode in the touch display panel receives the signal, and the signal change of the coordinate point is transmitted to an IC, and the IC calculates the touch position of the active stylus, thereby realizing the scribing effect of the active stylus. The touch display panel provided by the invention is provided with the active control pen, so that the interference of display signals in the liquid crystal screen on the emission signals (namely, touch signals) of the active touch pen can be effectively shielded, and the scribing sensitivity of the active touch pen is greatly improved.
In a specific implementation, in the touch display panel provided by the embodiment of the present invention, the shielding electrode 104 may be made of a metal material, and in order not to affect the pixel aperture ratio, the shielding electrode 104 may have a grid structure located in the area where the pattern of the black matrix layer 103 is located, as shown in fig. 1 and 3. It is to be understood that the pattern of the shielding electrode 104 is not limited to the grid-like structure as long as it is located in the region where the pattern of the black matrix layer 103 is located. In addition, compared with the scheme of manufacturing the electrode by using the indium tin oxide material commonly used in the prior art, the shielding electrode 104 is manufactured by using the metal material (such as aluminum, copper, silver and the like), so that the raw material cost is greatly reduced.
In a specific implementation, in the touch display panel provided by the embodiment of the present invention, the shielding electrode 104 may be made of a transparent conductive material, and at this time, the transparent conductive material does not affect the pixel aperture ratio, so that the shielding electrode 104 may be disposed on the entire side of the upper substrate 101 facing the black matrix layer 103, as shown in fig. 2. Of course, the pattern of the shielding electrode 104 made of the transparent conductive material may be a grid structure located in the region where the pattern of the black matrix layer 103 is located, which is not particularly limited herein.
In a specific implementation, in the touch display panel provided by the embodiment of the present invention, as shown in fig. 1 and fig. 2, the touch display panel may generally further include: a common electrode 105 disposed between the upper substrate 101 and the lower substrate 102; in order to avoid parasitic capacitance between the shielding electrode 104 and the common electrode 105 or the pixel electrode from affecting the display effect, the shielding electrode 104 and the common electrode 105 may be loaded with the same electrical signal.
In a specific implementation, in the touch display panel provided by the embodiment of the present invention, as shown in fig. 1 to 3, in order to improve the touch sensitivity, the touch electrode layer 106 may include: two layers of grid-shaped touch electrodes are overlapped. In addition, as shown in fig. 3, in order to improve the touch sensitivity and ensure the display quality, the mesh points of each grid-shaped touch electrode may be located in the area where the mesh points of the black matrix layer 103 are located, and the two layers of grid-shaped touch electrodes are staggered in the overlapping direction (the left-right direction as shown in fig. 3), where the grid shape of the grid-shaped touch electrode is diamond. In addition, as can be seen from fig. 3, the overlapping area of the shielding electrode 104 with the grid-shaped touch electrode in the area where the pattern of the black matrix layer 103 is located is very small, so that parasitic capacitance between the shielding electrode 104 and the grid-shaped touch electrode is effectively avoided electrically, and the increase of the resistance-capacitance load (RC loading) of the grid-shaped touch electrode is prevented.
Generally, in the touch display panel provided by the embodiment of the present invention, two layers of overlapped grid-shaped touch electrodes included in the touch electrode layer 106 are insulated from each other, for example, the insulation between the two layers may be achieved by disposing the first insulating layer 107 therebetween, as shown in fig. 1 and 2.
Specifically, in the touch display panel provided by the embodiment of the present invention, the touch display panel may further include: and a color resist layer disposed on a side of the black matrix layer 103 facing away from the upper substrate 101. As shown in fig. 1 and 2, the color resist layer is specifically shown to include red color resist R, green color resist G, and blue color resist B. In specific implementations, the color resist layer may further include a yellow color resist Y, a white color resist W, and the like, which are not limited herein.
Generally, in the touch display panel provided by the embodiment of the present invention, to increase the adhesion of the upper substrate 101, the touch display panel may further include: a second insulating layer 108 is disposed between the upper substrate 101 and the touch electrode layer 106, as shown in fig. 1 and 2.
Further, in the touch display panel provided by the embodiment of the present invention, as shown in fig. 1 and fig. 2, a third insulating layer 109 may be further disposed on a side of the touch electrode layer 106 facing away from the upper substrate 101, so as to protect the touch electrode layer 106.

Generally, in the touch display panel provided by the embodiment of the present invention, as shown in fig. 1 and fig. 2, the touch display panel may further include: the optically transparent resin layer 112 is disposed between the protective cover 111 and the polarizer 110 to improve the contrast of the touch display panel.
