With the pursuit of high screen ratio of mobile terminals, manufacturers will process rectangular display screens to obtain high-screen ratio shaped displays, as shown in Figure 1. Compared with the traditional display screen, the special-shaped screen generally has four corners processed into arcs, chamfers, and top grooves. The common processing technology for the special-shaped screen is laser cutting. When laser cutting, the laser is irradiated from the edge of the glass.

The thin film transistor glass 2 and / or the color filter film glass 1 includes edges or corners formed by laser cutting, and an edge of the sides or corners is provided for blocking the laser light from entering the terminal panel. Internal barrier structure.

In the terminal panel of some embodiments of the present disclosure, the blocking structure 5 in the thin film transistor glass 2 will block the laser light entering the terminal panel through the surface glass when the laser cuts the thin film transistor glass 2 so that it cannot continue to enter the interior; The blocking structure 4 in the light film glass 1 blocks the laser light entering the terminal panel through the surface glass when the color filter film glass 1 is laser cut, so that it cannot continue to enter the interior. In this way, after the laser light enters the terminal panel, damage to the internal transistors and signal wiring of the screen can be avoided.

Optionally, the blocking structure is disposed along a laser cutting path; or

The blocking structure is disposed at a start point and an end point of a laser cutting path.

Here, by knowing the set laser cutting path, the blocking structure can be set along the laser cutting path, or only at the start and end points of the laser cutting path to achieve the blocking of the laser.

As shown in FIG. 3, for the terminal panel of some embodiments of the present disclosure, the thin film transistor glass 2 mainly includes a first glass layer 201, a first metal layer 202, a buffer layer 203, a polysilicon layer 204, and a second insulating layer 205 (including a gate Extreme silicon oxide insulation (Gate Insulator_SiOx, GI_SiOx) layer 2051 and gate silicon nitride insulation (Gate Insulator_SiNx, GI_SiNx) layer 2052), gate molybdenum layer 206, first insulation layer 207 (including interlayer silicon nitride insulation (Interlayer Dielectric_SiNx, ILD_SiNx) layer 2071 and interlayer silicon oxide insulation (Interlayer Dielectric_SiOx, ILD_SiOx) layer 2072), source-drain titanium aluminum titanium metal layer 208, first planarization (PLN) layer 209, common electrode indium tin oxide 1 ( Indium Tin Oxide (ITO1) layer, a third insulating layer 210, a pixel electrode ITO2 layer, and an alignment (Polyimide (PI) layer 211). The first metal layer 202 is a light-shielding layer made of molybdenum metal, the buffer layer 203 is made of silicon oxide SiOx, the first insulating layer 210 is made of silicon nitride SiNx, and the ITO1 and ITO2 layers in the frame region are etched away. The color filter glass 1 mainly includes a second glass layer 101, a black matrix (BM) layer 102, a red, yellow and blue RGB color filter film layer, a second overcoat (OC) layer 103, and a support pillar ( Photo Spacer (PS) layer and alignment film PI layer. Here, the PS layer and PI layer are omitted in the border area.

Optionally, as shown in FIG. 3, the blocking structure is a first reflective layer 212 in the thin film transistor glass 2, and the first reflective layer 212 is formed between the first glass layer 201 and the buffer layer 203. And corresponding to the laser cutting area.

In this way, through the first reflective layer 212 between the first glass layer 201 and the buffer layer 203, since the first reflective layer 212 is provided corresponding to the laser cutting area, the first glass layer 201 can be penetrated during the cutting process. Laser absorption or reflection reduces the probability that the laser continues to enter the terminal panel.

Of course, the first reflective layer 212 can also be disposed between other two layers, such as between the areas where the buffer layer 203 and the GI_SiOx layer 2051 are in contact with each other, or between the areas where the GI_SiOx layer 2051 and the ILD_SiNx layer 2071 are in contact with each other, etc., but At this time, the first reflective layer 212 is far away from the first glass layer 201, and the effect of preventing the laser from continuing to enter the terminal panel is worse than the above implementation.

In consideration of the manufacturing process of the thin film transistor glass 2, optionally, the first reflective layer 212 is formed by etching the first metal layer 202 on the first glass layer 201 based on the laser cutting area. The first metal layer 202 is obtained.

It should be understood that, in order to obtain the first metal layer 202 on the first glass layer 201 as shown in FIG. 3, the first metal layer 202 needs to be deposited on the first glass layer 201 and then etched, so that it can be retained. The required part. Therefore, in this etching process, the first reflective layer 212 can also be retained based on the laser cutting area, without adding a new process flow, which saves costs. The first reflective layer 212 and the first metal layer 202 are made of the same metal, such as molybdenum.

In addition, in the embodiment of the present disclosure, the blocking structure is a groove corresponding to a laser cutting region in the thin film transistor glass.

Through the groove corresponding to the laser cutting area, the laser light penetrating the first glass layer 201 is reflected after hitting the groove interface, reducing the probability that the laser light continues to enter the inside of the terminal panel.

The opening of the groove 501 is located on the alignment layer 211 and extends to the first glass layer 201 through the third insulating layer 210, the first planarizing layer 209, the first insulating layer 207, the GI_SiOx layer 2051, and the buffer layer 203. The grooves 501 are sequentially obtained when forming the layers. For example, after the first planarization layer 209 is formed, a first groove is obtained to obtain a first groove deep to the buffer layer 203. Then, a first groove is formed. The three insulating layers 210 are grooved a second time on the third insulating layer 210 corresponding to the first groove, and the groove wall retains the third insulating layer 210 of a predetermined thickness; then, an alignment layer 211 is formed, corresponding to the third insulating layer. The groove on the layer 210 is grooved for the third time, and the groove wall retains the alignment layer 211 of a predetermined thickness. Finally, when the thin film transistor glass 2 and the color filter glass 1 are bonded by the frame adhesive 3, the frame adhesive 3 is used. Fill the space in the third trench. Of course, the above-mentioned formation process of the groove 501 is only an implementation, and the groove can also be dug from the buffer layer 203 to the alignment layer 211, which is not repeated here.

Here, different reflective layers are provided in the groove 601 to work together to reduce the probability that the laser continues to enter the terminal panel.

Optionally, the second reflective layer 6011 is obtained by etching the second metal layer 208 after the second metal layer 208 is formed on the first insulating layer 207.

Here, a new process flow for forming the second reflective layer 6011 can be omitted. After trenching in the first insulating layer 207, a portion of the second metal layer 208 shown in FIG. 6 can be obtained on the first insulating layer 207. In the etching process, the second metal layer 208 in the groove is retained as the second reflective layer 6011 in the groove, thereby achieving the purpose of saving costs.

It should also be known that, as shown in FIG. 7, in the embodiment of the present disclosure, the blocking structure is a groove 701 corresponding to a laser cutting region in the color filter glass 1;

The opening of the groove 701 is located on the second planarization layer 102 and extends toward the second glass layer 101;

The groove 701 is filled with a resin material.

Here, through the groove 701 corresponding to the laser cutting area and opened on the second planarization layer 102, the filled resin material blocks the laser light penetrating the second glass layer 101 from entering the terminal panel, and the laser light continues to enter the terminal panel. The probability. Of course, the groove 701 may extend to the second glass layer 101 through the BM layer 102.
