Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

In a conventional panel design, in order to prevent ESD (Electro-Static discharge) from occurring due to Static electricity accumulation on the panel surface, a ground lead is usually disposed at the edge of the panel; in order to enable the screen to form a touch effect, the touch layer is arranged On the front face of the panel, the grounding lead and the touch layer are located On the outer side of the screen and are independent from the internal core function area, and the core function area is not affected while static electricity is released.

As shown in fig. 1, in a conventional panel design, an On-Cell touch product (e.g., Single layer On-Cell, SLOC touch product) is usually disposed with an ITO grounding lead (GND lead) On a frame Area at a distance (about 1 mm) away from an outer side of an AA Area (Active Area) to guide external static electricity to avoid affecting the inside of the touch Area, however, since the GND lead is isolated outside the AA region, the ground lead and the AA region are separated from each other, the frame at the bottom is a Black Matrix (BM), and the GND lead wire often adopts the large-width lead wire to arrange in order to ensure electrically conductive effect, can lead to corresponding lead wire discernment easily under the reflection light source when final outward appearance reflection inspection, leads to the impression of screen outward appearance to descend, influences the outward appearance visual experience and carries out bad judgement to MDL detection operation personnel simultaneously and causes the interference.

Example one

As shown in fig. 2, the present embodiment provides a touch panel, which includes a display area 1(AA area) and a frame area 2(BM area), wherein the frame area 2 is disposed with a ground lead 3 independent of the display area 1, and the frame area 2 is configured with a Mosaic area 4(Mosaic area) to obscure the boundary between the ground lead 3 and the display area 1.

In practical application, the Pattern of the mosaic area is an island-shaped Pattern, the Pattern is a Dummy mosaic Pattern (Dummy mosaic Pattern) made of ITO, and the Dummy mosaic Pattern can be manufactured on the outer surface of the corresponding touch layer. By introducing the Dummy mosaic Pattern, the boundary between the display area 1 and the grounding lead 3 can be blurred visually, the grounding lead area is not independent in appearance and is difficult to perceive, and meanwhile, as the Dummy mosaic Pattern is designed into an island-shaped structure, the effect of electrostatic guidance can be achieved under the condition that the display area 1 and the grounding lead 3 are not conducted.

In order to make the inside of the display area 1 and the area where the ground lead 3 is located visually uniform in appearance, in some cases, as shown in fig. 3, the mosaic area 4 is disposed in the frame area 2 between the ground lead 3 and the display area 1. The mosaic region 4 is disposed entirely between the ground lead 3 and the display region 1, and in this case, the mosaic region 4 functions to obscure the intermediate region between the ground lead 3 and the display region 1.

In some embodiments, as shown in fig. 4, the mosaic region is disposed in the frame region between the ground lead 3 and the display region 1, and in the frame region outside the ground lead 3. The mosaic area 4 is simultaneously arranged between the grounding lead 3 and the display area 1 and outside the grounding lead 3, so that the mosaic area 4 can enable the front appearance expression area of the whole touch panel to be covered by the ITO film layer, the surface of the whole touch panel is integrated on the lower side of the ITO film layer, and the front appearance expression of the whole touch panel is ensured to be the same.

In practical applications, a touch panel and a backlight module are often bonded by using a bonding Tape (Cell Tape) to prevent dust from entering the interior, considering that the bonding Tape usually covers the position of the frame region 2, when the bonding Tape is located near the position corresponding to the ground lead 3, the ground lead 3 can be shielded, so that the boundary between the fuzzy ground lead 3 and the display region 1 can be realized according to the mosaic region configuration mode shown in fig. 3, in some cases, the bonding Tape is located at a certain distance outside the ground lead 3, at this time, the mosaic region 4 is configured in the frame region between the ground lead 3 and the display region 1 and the frame region between the ground lead 3 and the bonding Tape to blur the region between the ground lead 3 and the bonding Tape, at this time, the mosaic region 4 can make the front appearance region of the whole touch panel be covered by an ITO film layer, the front appearance of the whole touch panel is guaranteed to be the same.

In some embodiments, the area ratio between the ITO area and the blank area in the mosaic area 4 is consistent with the area ratio between the ITO area and the blank area in the display area 1, which is generally satisfied that the ITO area to blank area ratio of the mosaic area 4 is substantially consistent with the ratio inside the display area 1, so that the visual effect of the mosaic area and the display area 1 is consistent, thereby well achieving the effect of blurring the boundary of the ground lead 3 and the display area 1.

In practical applications, the pattern inside the display area 1 and the pattern of the mosaic area 4 are both made of ITO, the pattern inside the display area 1 may be as shown in fig. 5, the pattern of the mosaic area 4 may be as shown in fig. 6, the white areas in fig. 5 and 6 are ITO pattern portions 5, the black areas are blank areas 6, the ITO patterns inside the display area 1 are connected with each other, and the ITO patterns of the mosaic area 4 are independent from each other and distributed in an isolated island shape.

In some embodiments, the ratio of the area of the ITO area to the clear area of the pattern of mosaic area 4 presents an increasing trend from display area 1 to ground lead 3. In practical applications, the area ratio of the ITO area to the blank area of the single pattern of the mosaic area 4 may be configured to present an increasing trend from the display area 1 to the ground lead 3 to present the visual effect shown in fig. 7, so as to achieve a good pattern transition and further improve the visual blurring effect.

The embodiment of the utility model provides a touch panel introduces Dummy mosaic Pattern between its display area and external ground lead, and limit between fuzzy AA district and the ground lead district in macroscopic view makes the ground lead region no longer independent in appearance, is difficult to be perceived, simultaneously because Dummy mosaic Pattern designs for isolated island structure, can reach the effect of static guide under the condition of guaranteeing not switching on between AA district and the GND lead wire.

Example two

The embodiment provides a display device, which comprises a display panel and the touch panel of the first embodiment.

In practical applications, the display device may be an On-Cell touch display device, especially a Single layer On-Cell (SLOC) type touch device. By rearranging and planning the edge Dummy area of the SLOC type touch control product, the ITO Dummy patterns distributed in an island shape are added On the boundary between the display area and the grounding lead at the periphery of the grounding lead, and the boundary between the grounding lead and the display area is blurred under the condition of ensuring that the grounding lead is not conducted with the inside of the display area, so that the appearance visual perception of the On-Cell touch control product is improved.
