Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

A touch screen assembly 1 for a display screen 100 of an electronic device 1000 according to an embodiment of the present application is described below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 5, the electronic device 1000 has a display screen 100, the display screen 100 has a window area 3, a camera 200 is disposed inside the electronic device 1000, and the touch screen assembly 1 includes: a TFT (Thin Film Transistor) wiring layer 12, an upper protective layer 11, and a lower glass layer 13.

Specifically, as shown in fig. 3 and 5, the TFT wiring layer 12 is formed substantially in a rectangular shape, and the outer contour line of the TFT wiring layer 12 includes a first side 124 to a fourth side 127 connected in this order. For example, in the embodiment shown in fig. 3, the outer contour line of the TFT wiring layer 12 includes a first side 124, a second side 125, a third side 126, and a fourth side 127, which are connected in this order.

As shown in fig. 3 and fig. 5, the TFT circuit layer 12 has an ITO (Indium tin oxide) routing area 121 and a metal routing area 122, the ITO routing area 121 is opposite to the window area 3, the metal routing area 122 is located outside the ITO routing area 121 and outside the window area 3, the metal routing area 122 extends along the length direction from the first side 124 to the third side 126, and the camera 200 is close to the fourth side 127. Note that the ITO routing region 121 is a transparent region.

Therefore, the fingerprint identification of the full screen range of the electronic device 1000 can be realized, so that the difficulty of unlocking the display screen 100 by a user can be reduced, and the convenience of use of the user is improved. For example, in the embodiment shown in fig. 3, the TFT line layer 12 is formed in a substantially rectangular shape, the metal trace region 122 is located on the left side (a side shown in fig. 3), the right side (b side shown in fig. 3) and the lower side (c side shown in fig. 3) of the window region 3, and the camera 200 is located near the upper side (d side shown in fig. 3) of the TFT line layer 12.

In the related art, when a user unlocks a display screen, the user needs to place a finger in a specific area to identify a fingerprint. In the embodiment of the present application, the TFT line layer 12 may be used as a main body for capacitive full-screen fingerprint identification, and when a user unlocks the display screen 100, the TFT line layer 12 may identify a fingerprint by only placing a finger on the window area 3 of the display screen 100, so that the fingerprint identification in the full-screen range of the electronic device 1000 may be implemented.

As shown in fig. 2 and 3, the upper protection layer 11 and the TFT circuit layer 12 are stacked, and a first shielding layer 111 is disposed on a region of the upper protection layer 11 opposite to the metal trace region 122. The upper protection layer 11 has a protection effect on the TFT circuit layer 12, and can prevent the TFT circuit layer 12 from being directly exposed, so that the reliability of the operation of the TFT circuit layer 12 can be improved.

It should be noted that the metal routing area 122 is an area visible to the naked eye, and the first shielding layer 111 is disposed on the area of the upper protection layer 11 opposite to the metal routing area 122, so that the first shielding layer 111 can shield the metal routing area 122, and the metal routing area 122 is prevented from being exposed in a visible range, thereby improving the aesthetic property of the display screen 100.

As shown in fig. 5, 9 and 10, the lower glass layer 13 is provided to be laminated with the TFT wiring layer 12 and is located on a side of the TFT wiring layer 12 away from the upper protective layer 11. The camera 200 is located on a side of the lower glass layer 13 away from the TFT wiring layer 12 and a lens 201 of the camera 200 faces the lower glass layer 13. The area of the lower glass layer 13 opposite to the camera 200 is provided with a second shielding layer 131. The second blocking layer 131 has a first light transmitting region 1311 opposite to the lens 201 of the camera 200. The lower glass layer 13 is closer to the lens 201 than the upper protective layer 11, and the height difference between the first light-transmitting region 1311 of the second shielding layer 131 and the lens 201 of the camera 200 is smaller by disposing the second shielding layer 131 on the lower glass layer 13.

It can be understood that the first light-transmitting region 1311 is located at an upper layer of the lens 201, external light needs to pass through the first light-transmitting region 1311 before entering the lens 201, and because a height difference between the first light-transmitting region 1311 and the lens 201 is reduced, shielding of the first light-transmitting region 1311 on light entering the lens 201 is also reduced, so that the lens 201 can capture light in a wider angle range, and further, shooting at a wider wide angle (such as an angle α shown in fig. 5) of the camera 200 can be achieved.

It should be noted that the TFT circuit layer 12 recognizes fingerprints through the principle of capacitance sensing, and in order to ensure the success rate of the TFT circuit layer 12 in recognizing fingerprints, the thickness of the upper protection layer 11 cannot be too thick, which may reduce the structural strength of the upper protection layer 11 to a certain extent. In order to ensure the stability of the TFT circuit layer 12 structure, in the embodiment of the present application, the lower side of the TFT circuit layer 12 is provided with the lower glass layer 13, and the lower glass layer 13 can promote the stability of the TFT circuit layer 12 structure together with the upper protection layer 11.

According to the touch screen assembly 1 for the display screen 100 of the electronic device 1000 in the embodiment of the application, the second shielding layer 131 is arranged in the area, opposite to the camera 200, of the lower glass layer 13, and the second shielding layer 131 is provided with the first light transmitting area 1311 opposite to the lens 201 of the camera 200, so that the height between the first light transmitting area 1311 and the lens 201 can be shortened, light rays in a larger angle range can penetrate through the first light transmitting area 1311 to be incident into the lens 201, the visual angle of the lens 201 can be increased, and then the large-wide-angle shooting of the camera 200 can be realized.

According to some embodiments of the present application, as shown in fig. 1, 4 and 5, the second shade layer 131 extends in a ring shape along the circumferential direction of the lower glass layer 13. This reduces the difficulty in processing the second shielding layer 131, and shortens the processing cycle of the second shielding layer 131. In addition, the second shielding layer 131 extending in a ring shape can shield the internal components of the electronic device 1000, so that the aesthetic property of the electronic device 1000 is further improved.

According to some embodiments of the present application, as shown in fig. 1, 3, 7, and 8, the second blocking layer 131 extends along an edge of the lower glass layer 13 opposite the fourth edge 127. Thus, the difficulty in processing the second shielding layer 131 is reduced, and the processing cycle of the second shielding layer 131 is shortened. In addition, the second shielding layer 131 extending along the edge of the lower glass layer 13 opposite to the fourth edge 127 can also shield components of the electronic device 1000 near the top, so as to improve the aesthetic property of the electronic device 1000.

In some embodiments of the present application, as shown in fig. 1, 3, 7 and 8, both ends of the second blocking layer 131 in the length direction respectively extend to both ends of an edge of the lower glass layer 13 opposite to the fourth edge 127. Therefore, the projection of the second shielding layer 131 on the TFT circuit layer 12 and the projection of the first shielding layer 111 on the TFT circuit layer 12 can form a seamless ring shape, so as to prevent components inside the electronic device 1000 from being exposed in a visible range, and make the electronic device 1000 more visually attractive.

Further, as shown in fig. 1, 3, 7 and 8, projections of both ends of the second shielding layer 131 in the longitudinal direction on the TFT wiring layer 12 have overlapping regions with projections of both ends of the first shielding layer 111 in the longitudinal direction on the TFT wiring layer 12, respectively. Therefore, the projection of the second shielding layer 131 on the TFT circuit layer 12 and the projection of the first shielding layer 111 on the TFT circuit layer 12 can be formed into a seamless ring shape, so that the requirement for the processing accuracy of the first shielding layer 111 and the second shielding layer 131 can be reduced, and the processing cost of the first shielding layer 111 and the second shielding layer 131 can be reduced.

According to some embodiments of the present disclosure, as shown in fig. 1, 9, and 10, the first blocking layer 111 extends in a ring shape along a circumferential direction of the upper protection layer 11, the first blocking layer 111 has a second light-transmitting region 1111 (refer to fig. 11) opposite to the lens 201 of the camera 200, and a diameter of the second light-transmitting region 1111 is larger than a diameter of the first light-transmitting region 1311. Therefore, the processing difficulty of the first shielding layer 111 can be reduced, and the processing period of the first shielding layer 111 can be shortened. In addition, the first shielding layer 111 extending annularly along the circumferential direction of the upper protection layer 11 can also shield components near the top of the electronic device 1000, so that the aesthetic property of the electronic device 1000 is further improved.

In some embodiments of the present application, as shown in fig. 9 and 10, the radius of the second light-transmitting region 1111 is r1, the radius of the first light-transmitting region 1311 is r2, and: r1-r2 is more than or equal to 0.5mm and is more than or equal to 1.2 mm. Alternatively, r1-r2 is 0.58mm, 0.87mm, 1.02mm or 1.15 mm.

Further, as shown in fig. 1, 9, and 10, the projection of the second light-transmitting region 1111 onto the TFT wiring layer 12 is located within the projection of the second shielding layer 131 onto the TFT wiring layer 12 (see fig. 11). Therefore, the projection of the second shielding layer 131 on the TFT circuit layer 12 and the projection of the first shielding layer 111 on the TFT circuit layer 12 can form a seamless ring shape, so as to prevent the base 202 of the camera 200 or other components inside the electronic device 1000 from being exposed in a visible range, and make the electronic device 1000 more visually attractive.

According to some embodiments of the present application, as shown in fig. 3, 4 and 6, adjacent two sides of the TFT wiring layer 12 are connected by an arc-shaped side, and the shape and size of the upper protective layer 11 and the lower glass layer 13 are substantially the same as those of the TFT wiring layer 12. Therefore, the matching degree among the upper protective layer 11, the lower glass layer 13 and the TFT circuit layer 12 can be improved, and the structural strength and the operational reliability of the TFT circuit layer 12 can be further improved.

Further, as shown in fig. 3, two ends of the metal trace area 122 in the length direction respectively extend to the arc-shaped edge between the fourth edge 127 and the first edge 124 and the arc-shaped edge between the fourth edge 127 and the third edge 126. Therefore, the metal routing area 122 is better matched with the ITO routing area 121, so that the working stability of the TFT circuit layer 12 can be improved.

According to some embodiments of the present application, as shown in fig. 1 and fig. 2, the metal trace region 122 is located within a projection of the first blocking layer 111 on the TFT line layer 12. Therefore, the first shielding layer 111 can shield the metal routing area 122, so as to prevent the metal routing area 122 from being exposed in the visible range of the user, and further improve the aesthetic property of the display screen 100.

Further, as shown in fig. 1 and fig. 3, the TFT line layer 12 has a terminal 123, the terminal 123 has a connection region 1231, the connection region 1231 is located outside the metal trace region 122, and the connection region 1231 is located in the projection of the first shielding layer 111 on the TFT line layer 12. Therefore, the first shielding layer 111 can shield the connection region 1231, so as to prevent the connection region 1231 from being exposed in the visible range of the user, and further improve the aesthetic degree of the display screen 100.

According to some embodiments of the present application, as shown in fig. 6 and 7, at least one of the first and second shielding layers 111 and 131 is an ink layer. In other words, only the first shielding layer 111, only the second shielding layer 131, or both the first shielding layer 111 and the second shielding layer 131 may be ink layers. The ink layer has the advantages of simple manufacture and high shading rate.

Preferably, the ink layer is printed on the upper protective layer 11 or the lower glass layer 13 by a screen printing process. The silk-screen printing process has the advantages of being simple in operation and high in adaptability, the manufacturing difficulty of the ink layer can be reduced, the production efficiency of the ink layer is improved, and the production cost of the ink layer is reduced by adopting the silk-screen printing process.

Alternatively, the upper protective layer 11 is a glass plate member, an acrylic plate member, a PC (polycarbonate) plate member, or a PI film (polyimide film) plate member. Glass sheet spare, acrylic plate spare, PC (polycarbonate) sheet spare and PI membrane (polyimide film) sheet spare all have the advantage that structural strength is high and the transparency is high. Specifically, an appropriate sheet member may be selected according to the model of the electronic apparatus 1000 or the applicable environment of the electronic apparatus 1000.
