fig. 2 is a schematic view of a black touch screen provided by the present invention;
fig. 3 is a schematic view of the black touch display module according to the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Example one
As shown in fig. 1, a black touch screen includes a glass cover plate 11 having a black ink layer 14 on a peripheral area of a back surface thereof, and a touch film 12, wherein the touch film 12 is completely attached to a visible area of the back surface of the glass cover plate 11 through an optical adhesive 13, and the touch film 12 includes a gray transparent film 121 and a touch circuit 122 fabricated on a surface of the gray transparent film 121 facing the glass cover plate 11.
In the black touch screen, the touch circuit 122 is manufactured on the gray transparent film 121 to form the touch film 12, and the gray color of the gray transparent film 121 can increase the color depth of the visible area in the screen-saving state, and reduce the color difference between the screen-saving color of the visible area and the ink black of the peripheral area, so that the visible area and the peripheral area approach to an integral black optical effect when the screen-saving state is realized.
Preferably, the optical glue 13 is a gray optical glue 13 to further increase the color depth of the visible area in the breath-hold state; the optical adhesive 13 may be, but not limited to, an OCA adhesive, carbon black particles are diluted in a base material of the OCA adhesive in proportion to form a gray optical adhesive 13, and the gray level of the gray optical adhesive can be controlled by controlling the addition amount and the color depth of the carbon black particles, so as to be suitable for the black ink layers 14 with different color depths.
Furthermore, a sunken groove is formed in the peripheral area of the back surface of the glass cover plate 11, and the black ink layer 14 is disposed in the sunken groove, so that the back surface of the peripheral area of the touch film 12 is lower than the back surface of the visible area thereof.
As shown in fig. 2, after the black touch screen 1 and the display screen 2 are bonded together by the sealant 3, the thickness of the air layer between the black touch screen 1 and the display screen 2 is also an important factor that affects the degree of color difference between the rest screen color of the visible region and the ink black of the peripheral region, and the peripheral region of the touch film 12 is sunk, so that when the sealant 3 with the same thickness is bonded, the thickness of the air layer between the black touch screen 1 and the display screen 2 is reduced, and the color difference between the rest screen color of the visible region and the ink black of the peripheral region can be reduced.
