[0020] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.
[0021] A touch panel structure with a wood grain pattern, referring to Figure 1 and Figure 2, including a touch panel 10, the touch panel 10 includes a tempered glass 20, a wood grain film 30, and a touch sensing function layer 40 arranged in sequence. The tempered glass 20 is colorless and transparent, and the shape of the tempered glass 20 can be rectangular, circular, oval, etc.
[0022] Refer to Figure 2 , the wood grain film 30 is located below the tempered glass 20. An OCA optical adhesive 50 for bonding and fixing is provided between the wood grain film 30 and the tempered glass 20. The OCA optical adhesive 50 is colorless and transparent, and the OCA optical adhesive 50 bonds the wood grain film 30 and the tempered glass 20 together.
[0023] Refer to Figure 2 , the wood grain film 30 includes a PMMA film 31, a wood grain printing layer 32, and a substrate layer 33 stacked in sequence from top to bottom. The wood grain printing layer 32 is used to make the wood grain film 30 present a wood grain effect, and the substrate layer 33 is made of PMMA or ABS material. The wood grain film 30 is located between the PMMA film 31 and the substrate layer 33, thus forming a film-like structure with a wood grain effect.
[0024] Refer to Figure 2 , a black light-shielding ink 60 is screen-printed on the side of the wood grain film 30 facing away from the tempered glass 20. The black light-shielding ink 60 is used to shield the non-light-transmitting area.
[0025] Refer to Figure 2 , the touch sensing function layer 40 is arranged on one side of the black light-shielding ink 60, and the touch sensing function layer 40 is located on the side of the black light-shielding ink 60 away from the wood grain film 30. The touch sensing function layer 40 is used to make the touch panel 10 have a touch function, and the touch sensing function layer 40 is made of metal mesh, nano silver, or ITO material.
[0026] Refer to Figure 1 and Figure 2 , the touch panel 10 is composed of a middle display area 11 and a non-display area 12 arranged on the periphery of the display area 11. The middle display area 11 is a light-transmitting area and a touch area, used to display a picture for consumers to clearly see. The non-display area 12 is a non-light-transmitting area and does not perform display.
[0027] Further, refer to Figure 1 and Figure 2 , the black light-shielding ink 60 is arranged relative to the position of the non-display area 12 of the touch panel 10. The black light-shielding ink 60 is screen-printed within the range of the non-display area 12 to achieve a light-shielding effect and prevent light from leaking out from the non-display area 12.
[0028] Refer to Figure 1 and Figure 2, a black cover-back ink 70 is screen-printed below the touch sensing function layer 40. The black cover-back ink 70 is screen-printed at a position relative to the non-display area 12, and the black cover-back ink 70 is used to further block light from the non-display area 12 of the touch panel 10.
[0029] Referring to Figure 1 and Figure 2 , an FPC 80 is bonded to the touch sensing function layer 40. One end of the FPC 80 is bonded to the touch sensing function layer 40, and the other end of the FPC 80 is used to connect to the customer main board to enable the normal use of the touch sensing function layer 40. A touch bonding position 41 is provided on the touch sensing function layer 40. An FPC bonding position 81 is provided at one end of the FPC 80 bonded to the touch sensing function layer 40. The FPC bonding position 81 and the touch bonding position 41 are conductively bonded through ACF.
[0030] Further, referring to Figure 2 , the black cover-back ink 70 is hollowed out at the bonding positions relative to the FPC bonding position 81 and the touch bonding position 41 to avoid the black cover-back ink 70 affecting the bonding of the FPC 80 and the touch sensing function layer 40.
[0031] Referring to Figure 1 and Figure 2 , the structure of the touch panel 10 is made to present a wood grain effect by setting a wood grain film 30. When the touch panel 10 is in use, the display area 11 is set to be light-transmissive, so as not to affect the normal display of the touch panel 10. When the touch panel 10 is turned off, the entire touch panel 10 presents an overall wood grain effect to meet the consumer's requirements for the appearance of the touch panel 10.
[0032] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
