Description

Technical Field

[0001] The utility model relates to the technical field of displays, and in particular to an embedded touch display panel and a display device. Background Art

[0002] Liquid crystal display panels have the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and they dominate the field of flat panel displays. With the rapid development of display technology, touch display panels have been widely accepted and used by people, such as smart phones and tablet computers. Touch display panels use embedded touch technology to combine touch panels and liquid crystal display panels into one, and embed the touch panel function into the liquid crystal display panel, so that the liquid crystal display panel has the functions of displaying and sensing touch input at the same time.

[0003] According to the different settings of the touch sensing layer in the display panel, the touch display panel is divided into add-on mode, in-cell and on-cell structures. The in-cell touch screen integrates the touch function into the display screen, which can effectively reduce the thickness of the entire display and simplify the production process, making the product thinner and lighter, and the production cost is lower, thus it is widely popular. At present, for the in-cell touch screen, the touch screen structure is usually set directly on the array substrate, mainly in the array substrate. Some structural components used to transmit display signals are reused as touch electrodes. The more common is to reuse the common electrode block as the touch electrode. Not only the scan lines and data lines need to be set on the array substrate, but also the touch wiring needs to be set, and then the common signal and touch signal are transmitted to the common electrode block through the touch wiring.

[0004] like Figure 1 and Figure 2 The existing self-contained embedded touch display panel includes an array substrate 20, on which a plurality of common electrode blocks 21 and a plurality of touch lines 22 are provided. The common electrode blocks 21 are reused as touch electrodes to realize touch control. The plurality of common electrode blocks 21 are used to receive touch signals and common voltages in a time-sharing manner. When the common electrode blocks 21 are used for touch control, the common electrode blocks 21 are used to receive touch signals; when the common electrode blocks 21 are used as common electrodes, the common electrode blocks 21 are used to receive common voltages. The touch lines 22 are used to electrically connect the common electrode blocks 21 and the touch chip 100. There are two existing ways of routing the touch lines 22 on the array substrate 20:

[0005] For one of the Figure 1, each touch line 22 has the same length and extends from the far end of the touch chip 100 to be electrically connected to the touch chip 100, that is, each touch line 22 runs through the entire set of common electrode blocks 21, that is, each touch line 22 crosses the same number of common electrode blocks 21. This method is called a penetration method. Figure 2 In each column of common electrode blocks 21, the touch lines 22 electrically connected to each common electrode block 21 are of unequal lengths. Specifically, the touch lines 22 gradually shorten from left to right, that is, the number of common electrode blocks 21 crossed by the touch lines 22 gradually decreases from left to right. This method is called a non-penetrating method. For these two routing methods of the touch lines 22, each common electrode block 21 requires at least one corresponding touch line 22 to realize the touch function; in order to improve the touch effect, each common electrode block 21 corresponds to multiple touch lines 22 to apply touch signals. Therefore, the existing routing method of the touch lines 22 has a greater impact on the aperture ratio, thereby affecting the penetration rate, resulting in the penetration rate failing to meet customer requirements.

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation methods, structures, features and effects of the embedded touch display panel and display device proposed by the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments:

[0033] [Example 1]

[0034] Figure 3 It is a schematic diagram of the top plan structure of the array substrate in the first embodiment of the utility model. Figure 4 It is a schematic diagram of the longitudinal cross-section structure of the touch display panel in the first embodiment of the present utility model. Figure 5 It is a schematic diagram of the top plan structure of the color film substrate in the first embodiment of the utility model.

[0035] like Figures 3 to 5 As shown, an embedded touch display panel provided by the first embodiment of the utility model includes a color filter substrate 10, an array substrate 20 arranged opposite to the color filter substrate 10, and a liquid crystal layer 30 located between the color filter substrate 10 and the array substrate 20. A plurality of common electrode blocks 21 and a plurality of touch lines 22 arranged in an array are provided on the array substrate 20, and the common electrode blocks 21 are electrically connected to the corresponding touch lines 22, that is, the common electrode blocks 21 can be reused as touch electrodes. One end of the touch line 22 is electrically connected to the corresponding common electrode block 21, and the other end of the touch line 22 is electrically connected to the touch chip 100. The touch chip 100 applies a touch signal to the common electrode block 21 during the touch time period to realize the touch function.

[0036] like Figure 3As shown, the plurality of common electrode blocks 21 include a first common electrode block 211 and a second common electrode block 212, and the plurality of touch lines 22 include a first touch line 221 and a second touch line 222. One end of the first touch line 221 is electrically connected to the corresponding first common electrode block 211, and the other end of the first touch line 221 extends to the first edge 201 of the array substrate 20. One end of the second touch line 222 is electrically connected to the corresponding second common electrode block 212, and the other end of the second touch line 222 extends to the second edge 202 of the array substrate 20. A touch signal is applied to the common electrode block 21 from two opposite edges of the array substrate 20 to reduce the number of touch lines 22 in a direction perpendicular to the touch lines 22, thereby increasing the aperture ratio and improving the penetration rate. Among them, the first edge 201 and the second edge 202 are located at opposite ends of the embedded touch display panel, that is, the first touch line 221 and the second touch line 222 extend in opposite directions away from one end of the common electrode block 21. refer to Figure 3 In this embodiment, the first edge 201 is located at the lower end of the embedded touch display panel, and the second edge 202 is located at the upper end of the embedded touch display panel; of course, the upper end of the embedded touch display panel can also be defined as the first edge 201, and the lower end of the embedded touch display panel can be defined as the second edge 202; or the left / right end of the embedded touch display panel can be defined as the first edge 201, and the right / left end of the embedded touch display panel can be defined as the second edge 202.

[0037] In this embodiment, in a column of common electrode blocks 21, the first common electrode blocks 211 and the second common electrode blocks 212 are symmetrical about the perpendicular midline of the column of common electrode blocks 21, that is, in a column of common electrode blocks 21, the number of the first common electrode blocks 211 and the second common electrode blocks 212 are the same, the lower half of the column of common electrode blocks 21 is the first common electrode blocks 211, and the upper half is the second common electrode blocks 212; the first touch traces 221 and the second touch traces 222 on the same straight line are symmetrical about the perpendicular midline of the column of common electrode blocks 21, that is, the lengths of the first touch traces 221 and the second touch traces 222 on the same straight line are the same. Among them, the first touch traces 221 and the second touch traces 222 both extend along the column direction. Of course, in other embodiments, in a row of common electrode blocks 21, the first common electrode block 211 and the second common electrode block 212 are symmetrical about the perpendicular midline of the row of common electrode blocks 21, and the first touch wiring 221 and the second touch wiring 222 on the same straight line are symmetrical about the perpendicular midline of the row of common electrode blocks 21. The first touch wiring 221 and the second touch wiring 222 both extend along the row direction.

[0038] like Figure 4 and Figure 5As shown, the embedded touch display panel is provided with a jumper wire 40, one end of the jumper wire 40 is electrically connected to one end of the second touch wiring 222 at the second edge 202, and the other end of the jumper wire 40 extends to the first edge 201, and transmits the touch signal on the second touch wiring 222 from the second edge 202 to the first edge 201, so that the first touch wiring 221 and the second touch wiring 222 can be bound and the touch signal can be applied on the same side of the array substrate 20, so as to reduce the binding occupied area and reduce the frame.

[0039] In this embodiment, the jumper wire 40 is arranged on the color film substrate 10, and a conductive column is arranged between the color film substrate 10 and the array substrate 20, and the conductive column is located in the non-display area of ​​the edge. The conductive column includes a first conductive column 51 and a second conductive column 52, and one end of the jumper wire 40 is connected to the second conductive column 52 at the second edge 202 through the second conductive column 52 and one end of the second touch line 222, and the other end of the jumper wire 40 is conductively connected to the touch drive circuit 23 through the first conductive column 51. The touch signal on the second common electrode block 212 is first transmitted to the second edge 202 through the second touch line 222, then transmitted to the jumper wire 40 on the color film substrate 10 through the second conductive column 52, and then transmitted to the touch drive circuit 23 through the first conductive column 51, and finally transmitted to the touch chip 100 through the touch drive circuit 23. Among them, the touch driving circuit 23 is arranged in the non-display area, and is used to electrically connect the touch wiring 22 (the first touch wiring 221 and the second touch wiring 222) to the touch chip 100. The conductive column is, for example, a conductive particle or a conductive glue. The conductive glue can be ACA (anisotropic conductive glue) or ACF (anisotropic conductive film). ACA has a low curing temperature and a fast curing speed, which can effectively reduce thermal stress and avoid damage to the liquid crystal and the glass substrate caused by temperature changes during the curing process; while ACF needs to be heated and pressurized for curing, and the temperature change during the curing process causes the glass to deform. The jumper wire 40 is directly made on the color film substrate 10 through a mask process. The jumper wire 40 can be made of metals such as copper (Cu), silver (Ag), chromium (Cr), molybdenum (Mo), aluminum (Al), titanium (Ti), manganese (Mn), nickel (Ni), etc., or a combination of the above metals, such as Al / Mo, Cu / Mo, etc.; the jumper wire 40 can also be made of transparent conductive materials such as indium tin oxide (ITO) and indium zinc oxide (IZO).

[0040] Further, the jumper wire 40 is arranged on a side of the color filter substrate 10 away from the liquid crystal layer 30, and a first connection electrode 13 is arranged on the color filter substrate 10. Both ends of the jumper wire 40 are conductively connected to the first conductive column 51 and the second conductive column 52 through the first connection electrode 13, that is, one end of the jumper wire 40 is conductively connected to the first conductive column 51 through one first connection electrode 13, and the other end of the jumper wire 40 is conductively connected to the second conductive column 52 through another first connection electrode 13. In this embodiment, the first connection electrode 13 is arranged on the side of the color filter substrate 10, that is, the first connection electrode 13 is made on the side of the color filter substrate 10 through a side wiring process, so that there is no need to punch holes on the color filter substrate 10.

[0041] The color film substrate 10 is further provided with a black matrix 11 and a color resist layer 12. The multiple color resist layers 12 are distributed in an array in the display area and are separated from each other by the black matrix 11. The color resist layer 12 contains red (R), green (G), and blue (B) color resist materials, and correspondingly forms red (R), green (G), and blue (B) sub-pixels. The black matrix 11 not only separates the multiple color resist layers 12 in the display area from each other, but also completely covers the non-display area to avoid light leakage in the non-display area.

[0042] Preferably, the jumper wire 40 passes through the display area, that is, the jumper wire 40 directly passes through the display area from the first edge 201 of the color filter substrate 10 and extends to the second edge 202. Therefore, the jumper wire 40 does not need to be wired from the non-display area around the display area to reduce the area of ​​the non-display area and the frame. The jumper wire 40 preferably corresponds to the lines of the black matrix 11 to avoid affecting the light transmittance.

[0043] In this embodiment, the liquid crystal layer 30 preferably uses positive liquid crystal molecules, that is, liquid crystal molecules with positive dielectric anisotropy. In the initial state, the positive liquid crystal molecules in the liquid crystal layer 30 are aligned parallel to the color filter substrate 10 and the array substrate 20, and the alignment direction of the positive liquid crystal molecules close to the color filter substrate 10 is parallel or anti-parallel to the positive liquid crystal molecules close to the array substrate 20. Of course, in other embodiments, the liquid crystal layer 30 may also use negative liquid crystal molecules, and the negative liquid crystal molecules in the liquid crystal layer 30 may be aligned perpendicular to the color filter substrate 10 and the array substrate 20, that is, similar to the alignment mode of the VA display mode.

[0044] The array substrate 20 is formed into a plurality of pixel units on the side facing the liquid crystal layer 30 by a plurality of scan lines (not shown) and a plurality of data lines (not shown) which are insulated and crossed from each other. A pixel electrode 25 and a thin film transistor (not shown) are provided in each pixel unit. The pixel electrode 25 is electrically connected to the data line of the adjacent thin film transistor through the thin film transistor. The thin film transistor includes a gate, an active layer, a drain electrode and a source electrode. The gate electrode and the scan line are located in the same layer and are electrically connected. The gate electrode and the active layer are separated by an insulating layer. The source electrode is electrically connected to the data line, and the drain electrode is electrically connected to the pixel electrode 25 through a contact hole. The common electrode block 21 and the pixel electrode 25 can be made of transparent conductive materials such as indium tin oxide (ITO) and indium zinc oxide (IZO).

[0045] like Figure 4 As shown, the common electrode block 21 and the pixel electrode 25 are located in different layers and insulated and isolated by an insulating layer. The common electrode block 21 can be located above or below the pixel electrode 25. Preferably, the common electrode block 21 is a planar electrode arranged on the entire surface, and the pixel electrode 25 is a block electrode arranged in an entire block in each pixel unit or a slit electrode with multiple electrode strips to form a fringe field switching mode (Fringe Field Switching, FFS). Of course, the pixel electrode 25 and the common electrode block 21 can also be located in the same layer, but the two are insulated and isolated from each other, and the pixel electrode 25 and the common electrode block 21 can each include multiple electrode strips, and the electrode strips of the pixel electrode 25 and the electrode strips of the common electrode block 21 are arranged alternately to form an in-plane switching mode (In-Plane Switching, IPS).

[0046] Furthermore, an upper polarizer 71 is provided on the color filter substrate 10, and the upper polarizer 71 is provided on the side of the jumper wire 40 away from the color filter substrate 10. A lower polarizer 72 is also provided on the array substrate 20, and the light transmission axes of the upper polarizer 71 and the lower polarizer 72 are perpendicular to each other.

Figure 6 As shown, the embedded touch display panel provided in the second embodiment of the present invention is different from the one in the first embodiment ( Figures 3 to 5 ) are substantially the same, except that, in this embodiment:

[0049] In a column of common electrode blocks 21, the first common electrode blocks 211 and the second common electrode blocks 212 are alternately arranged, and the sum of the lengths of the first touch lines 221 and the second touch lines 222 on any straight line is the same as the sum of the lengths of the first touch lines 221 and the second touch lines 222 on another line, that is, the sum of the lengths of the first touch lines 221 and the second touch lines 222 on each straight line is the same length, so that the touch lines 22 on the array substrate 20 are more evenly distributed to enhance the display effect.

[0050] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of the first embodiment and will not be described in detail here.

[0051] [Example 3]

[0052] Figure 7 FIG. 1 is a schematic diagram of the longitudinal cross-sectional structure of the touch display panel in the third embodiment of the present utility model. Figure 7 As shown, the embedded touch display panel provided in the third embodiment of the present invention is different from the embedded touch display panel provided in the first embodiment ( Figures 3 to 5 )、Example 2 ( Figure 6 ) are substantially the same, except that, in this embodiment:

[0053] The first connection electrode 13 penetrates the color filter substrate 10 , that is, a hole is punched on the color filter substrate 10 by a punching process, and the first connection electrode 13 is arranged in the through hole, so as to play a certain protective role for the first connection electrode 13 and reduce the risk of the first connection electrode 13 being damaged.

[0054] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be described in detail here.

[0056] Figure 8 It is a schematic diagram of the longitudinal cross-section structure of the touch display panel in the fourth embodiment of the present utility model. Fig. 9 Schematic diagram of the bottom-up plan structure of the array substrate in the fourth embodiment of the present utility model. Figure 8 and Fig. 9 As shown, the embedded touch display panel provided in the fourth embodiment of the present invention is different from the one in the first embodiment ( Figures 3 to 5 )、Example 2 ( Figure 6 ) is basically the same as the embedded touch display panel in the embodiment, except that, in this embodiment: the jumper wire 40 is arranged on the array substrate 20, so there is no need to arrange the jumper wire 40 and the first connecting electrode 13 on the color film substrate 10, and there is no need to arrange a conductive column between the color film substrate 10 and the array substrate 20.

[0057] The jumper wire 40 and the touch control wiring 22 are located on different layers on the array substrate 20 and are spaced apart from each other. The jumper wire 40 is directly made on the array substrate 20 through a mask process. A second connection electrode 24 is provided in the non-display area of ​​the array substrate 20. Both ends of the jumper wire 40 are conductively connected to the second touch control wiring 222 and the touch control driving circuit 23 through the second connection electrode 24, that is, one end of the jumper wire 40 is conductively connected to one end of the second touch control wiring 222 through one second connection electrode 24, and the other end of the jumper wire 40 is conductively connected to the touch control driving circuit 23 through another second connection electrode 24.

[0058] In this embodiment, the jumper wire 40 is arranged on the side of the array substrate 20 away from the liquid crystal layer 30, and the second connection electrode 24 penetrates the array substrate 20, that is, a hole is punched on the array substrate 20 by a punching process, and the second connection electrode 24 is arranged in the through hole, so that the second connection electrode 24 can be protected to a certain extent and the risk of damage to the second connection electrode 24 can be reduced. Of course, the second connection electrode 24 can also be arranged on the side of the array substrate 20, that is, the second connection electrode 24 is made on the side of the array substrate 20 by a side wiring process, so that there is no need to punch holes on the array substrate 20. In other embodiments, the jumper wire 40 and the touch wiring 22 can also be arranged on the side of the array substrate 20 facing the liquid crystal layer 30, and the jumper wire 40 and the touch wiring 22 are separated from each other by an insulating layer or a flat layer, and the insulating layer or the flat layer is punched, and the second connection electrode 24 is arranged in the contact hole, but this will make the parasitic capacitance between the jumper wire 40 and other electrodes (scanning line, data line) larger, affecting the transmission of touch signals.

[0059] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be described in detail here.

[0061] Fig.10 Schematic diagram of the bottom plan structure of the array substrate in the fifth embodiment of the present utility model. Fig.10 As shown, the embedded touch display panel provided in the fifth embodiment of the present invention is different from the one in the first embodiment ( Figures 3 to 5 )、Example 2 ( Figure 6 ) are substantially the same, except that, in this embodiment:

[0062] The embedded touch display panel includes a flexible circuit board 60, and the jumper wire 40 is arranged on the flexible circuit board 60. The flexible circuit board 60 is located on the side of the array substrate 20 away from the liquid crystal layer 30. Therefore, there is no need to set the jumper wire 40 and the first connection electrode 13 on the color filter substrate 10, and there is no need to set a conductive column between the color filter substrate 10 and the array substrate 20. The touch signal on the second touch line 222 is directly transmitted from the second edge 202 to the first edge 201 through the flexible circuit board 60, and there is no need to use an additional mask process to make the jumper wire 40 on the color filter substrate 10 or the array substrate 20. It can be understood that in order not to affect the backlight module 80 ( Fig.11 ) provides light to the embedded touch display panel, the flexible circuit board 60 bypasses the backlight module 80 from the back side of the backlight module 80, and the two ends of the flexible circuit board 60 are then bound to the array substrate 20.

[0063] It should be understood by those skilled in the art that the rest of the structure and working principle of this embodiment are the same as those of Embodiment 1 and Embodiment 2, and will not be described in detail here.

Fig.11 As shown, this embodiment further provides a display device, including the touch display panel as described above and a backlight module 80. The backlight module 80 is disposed below the touch display panel and is used to provide a backlight source for the touch display panel.

[0065] The backlight module 80 includes a backlight source 81 and an anti-peep layer 82, and the anti-peep layer 82 is used to narrow the range of the light emission angle. A brightness enhancement film 83 is also provided between the backlight source 81 and the anti-peep layer 82, and the brightening film 83 increases the brightness of the backlight module 80. Among them, the anti-peep layer 82 is equivalent to a miniature shutter structure, which can block light with a larger incident angle and allow light with a smaller incident angle to pass through, thereby reducing the angle range of light passing through the anti-peep layer 82. The anti-peep layer 82 includes a plurality of parallel light-blocking walls and a light-transmitting hole located between two adjacent light-blocking walls, and light-absorbing materials are provided on both sides of the light-blocking walls. Of course, the backlight source 81 can also be a light-collecting backlight source, so there is no need to set the anti-peep layer 82, but the light-collecting backlight source is more expensive than the conventional backlight source.

[0066] The backlight module 80 can be an edge-type backlight module or a direct-type backlight module. Preferably, the backlight module 80 adopts a collimated backlight (CBL) mode, which can collect light and ensure the display effect.
