[0029] Embodiment 1
[0030] like Figures 1 to 4 As shown, an integrated black OGS touch screen integrated light sensing structure includes a glass substrate 1 and an ITO touch layer 3 arranged on the lower surface of the display area 12 of the glass substrate 1;
[0031] The non-display area 11 of the glass substrate 1 is bound with an FPC 2, and a light sensing IC 5 is arranged on the lower surface of the portion of the FPC 2 bound to the glass substrate 1. A main black ink layer 13 is arranged on the lower surface of the glass substrate 1 located in the non-display area 11, and a space-avoiding portion 4 is arranged on the main black ink layer 13 just above the light sensing IC 5, and the FPC 2 avoids the light sensing IC 5;
[0032] The lower surface of the main black ink layer 13 is screen-printed with reverse-cover black light-shielding ink 14 .
[0033] A semi-transparent black ink layer 41 is disposed on the lower surface of the glass substrate 1 at the air-avoiding portion 4 .
[0034] The utility model is provided with a photosensitive IC5 on the lower surface of the glass substrate 1, and the main black ink layer 13, the reverse cover black light-shielding ink 14 and the FPC2 are all free from the photosensitive IC5, and a semi-transparent black ink layer 41 is provided on the free from part 4, the semi-transparent black ink layer 41 can achieve the effect of one-piece black at ordinary times, and can also allow light to pass through the front of the glass substrate 1 through the semi-transparent black ink layer 41, and then pass through the free from part 4 of the FPC2 to enter the photosensitive IC5, so that the OGS touch screen has a photosensitive function, and because it can make the photosensitive IC5 can be directly set on the lower surface of the FPC2, the backlight brightness can be adjusted by the strength of the external light, and finally the screen brightness can be adjusted. In addition, the use of semi-transparent black tempered glass reduces the transmittance of the viewing area. When the screen is not lit, the one-piece black effect of the edge and the viewing area is better, thereby improving the product competitiveness of the OGS touch screen, so as to meet the growing quality requirements of enterprises.
[0035] Furthermore, a first PI reinforcing plate 25 is disposed on the upper surface of the FPC 2 at a position corresponding to the photosensitive IC 5 , and the first PI reinforcing plate 25 avoids the photosensitive IC 5 .
[0036] Furthermore, a black double-sided adhesive 26 is attached to the lower surface of the first PI reinforcing plate 25 and the glass substrate 1 , and the black double-sided adhesive 26 avoids the light sensing IC 5 .
[0037] Embodiment 2
[0038] As a further optimization solution of the first embodiment, in this embodiment, the glass substrate 1 is semi-transparent black tempered glass.
[0039] A protective film 6 is provided on the lower surface of the photosensitive IC 5 . The protective film 6 is a single-sided adhesive foam to protect the photosensitive IC 5 from being damaged.
[0040] Furthermore, a touch IC 21 is disposed on the upper surface of the FPC 2 , and a steel sheet reinforcement plate 22 is disposed on the lower surface of the FPC 2 located at the touch IC 21 . The steel sheet reinforcement plate 22 has a thickness of 0.2 mm.
[0041] In another preferred implementation manner of this embodiment, a double-sided tape 23 is provided on the lower surface of the steel sheet reinforcement plate 22, and the thickness of the double-sided tape 23 is 0.05 mm.
[0042] Furthermore, a plug-in terminal is provided at one end of the FPC2, and a second PI reinforcing plate 24 is provided on the lower surface of the FPC2 located at the plug-in terminal to enhance the strength of the plug-in terminal and facilitate plugging and unplugging of the plug-in terminal.
[0043] Embodiment 3
[0044] like Figure 5 and Figure 6 As shown, as a further optimization solution of the first embodiment, in this embodiment, a plurality of grooves 15 are formed on the upper surface of the glass substrate 1 by etching, and a plastic layer 7 is covered on the upper side of the glass substrate 1 , and the plastic layer 7 is embedded in the plurality of grooves 15 .
[0045] In this embodiment, the upper surface of the glass substrate 1 is covered with a plastic layer 7, and a plurality of grooves 15 are formed downwardly on the upper surface of the glass substrate 1 by etching, and a portion of the lower surface of the plastic layer 7 is embedded in each groove 15. Since the surface of the groove 15 formed by etching has a certain degree of roughness, the plastic layer 7 can be tightly bonded to the groove 15, thereby preventing the glass substrate 1 and the plastic layer 7 from falling off. Since the upper part of the glass substrate 1 is covered with a plastic layer 7, and a plurality of grooves 15 are formed on the upper surface of the glass substrate 1 by etching, and the plastic layer 7 can be embedded in the plurality of grooves 15, the grooves 15 formed by etching make the inner surface of the grooves 15 have a certain degree of roughness, and the surface of the grooves 15 with a certain degree of roughness can improve the bonding force between the grooves 15 and the plastic layer 7, thereby reducing the possibility of separation of the grooves 15 and the plastic layer 7. When the OGS touch screen is hit or dropped, the plastic layer 7 on the upper surface of the glass substrate 1 can directly withstand the external force, thereby preventing the external force from directly acting on the glass substrate 1. Since the plastic layer 7 can absorb most of the energy, the remaining external force is very weak when it acts on the glass substrate 1, thereby effectively reducing the risk of the glass substrate 1 being broken or damaged. Moreover, when the OGS touch screen is subjected to the external force, even if the external force is large, only the plastic layer 7 on the upper surface of the glass substrate 1 will be damaged, and the glass substrate 1 will not be directly damaged. Therefore, it can be avoided that the glass substrate 1 is damaged and the OGS touch screen cannot be used normally, thereby bringing a better user experience to the user and improving the anti-fall ability of the OGS touch screen.
[0046] Furthermore, the shape of the groove 15 can be square or circular, and the cross-sectional shape of the groove 15 can be a closing groove that is narrow on the outside and wide on the inside. In the present embodiment, the cross-sectional shape of the groove 15 is an isosceles trapezoid, and the groove 15 is in the shape of an elongated strip. The isosceles trapezoid-shaped groove 15 can make the plastic layer 7 tightly embedded in the groove 15, thereby preventing the groove 15 from being separated from the plastic layer 7, thereby preventing the glass substrate 1 from falling off from the plastic layer 7. The elongated groove 15 can increase the fitting portion between the plastic layer 7 and the groove 15, thereby improving the fitting strength between the groove 15 and the plastic layer 7.
[0047] Furthermore, the groove 15 is located in the non-display area 11 to prevent the groove 15 from affecting the normal display of the OGS touch screen.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the embodiments of the utility model can still be modified or replaced by equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the utility model.
