The naked-eye 3D touch control device comprises a first substrate (7), a second substrate (8) and a liquid crystal layer (30) which is located between the first substrate (7) and the second substrate (8), wherein a surface of the first substrate (7) which faces one side of the liquid crystal layer (30) is provided with a common electrode (1), an insulation layer (20) and a slit electrode unit (3) in sequence, and is also provided with a touch control electrode unit (2); the slit electrode unit (3) and the common electrode (1) are arranged opposite to each other; the touch control electrode unit (2) and the slit electrode unit (3) are arranged at intervals; each slit electrode unit (3) comprises at least two slit electrodes; and each touch control electrode unit (2) comprises at least two touch control electrodes, and the touch control electrodes located in the same touch control electrode unit (2) are arranged on the same layer and are insulated from each other. The 3D touch control device integrates the 3D display and touch control functions.
A: Provided are a 3D touch liquid crystal lens grating (11), a manufacturing method thereof, and a 3D touch display device (1). The 3D touch liquid crystal lens grating (11) comprises: a lower substrate (12), comprising a lower transparent substrate (121) and a surface electrode (122), the surface electrode (122) being formed on the lower transparent substrate (121); an upper substrate (13), in cell alignment with the lower substrate (12), and comprising an upper transparent substrate (131) and a strip-shaped electrode (132), the strip-shaped electrode (132) being formed on the upper transparent substrate (131); and liquid crystal, filled between the surface electrode (122) and the strip-shaped electrode (132). At least one touch electrode (133) is adjacently arranged between the upper transparent substrate (131) and the strip-shaped electrode (132), and a transparent isolation cushion layer (134) is arranged between the touch electrode (133) and the strip-shaped electrode (132). The 3D touch liquid crystal lens grating (11) can reduce the double-layer electrode used for touch control in the prior art to a single-layer electrode, thereby reducing the thickness of the 3D touch display device (1), simplifying the manufacturing process, and reducing the production cost of a product.
B: A display panel and a display device, relating to the technical field of display, and capable of improving the accuracy of touch recognition in touch display and reducing the occurrence probability of undesired touch operations. In the display panel, a mutual-capacitive touch film layer (2) comprises a driving electrode unit and a sensing electrode unit; one of the driving electrode unit and the sensing electrode unit is a first touch electrode unit (31), and the other one of the driving electrode unit and the sensing electrode unit is a second touch electrode unit (32); the first touch electrode unit (31) comprises a plurality of first touch electrodes (41) extending along a first direction (h1) and arranged along a second direction (h2) and a plurality of second touch electrodes (42) extending along the first direction (h1) and arranged along the second direction (h2); the plurality of first touch electrodes (41) have one-to-one correspondence to the plurality of second touch electrodes (42); the extension direction of the first touch electrodes (41) and the extension direction of the corresponding second touch electrodes (42) are located on the same straight line; and the first touch electrodes (41) and the corresponding second touch electrodes (42) are arranged at intervals.
C: A touch display panel (10) and a touch display device (20). The touch display panel (10) comprises a substrate (100) and multiple first touch electrode chains (200) and second touch electrode chains (300) arranged at intervals on the substrate (100). The first touch electrode chains (200) and the second touch electrode chains (300) are disposed to intersect and are insulated from one another. Each first touch electrode chain (200) comprises multiple first electrode units (210) consisting of first electrode lines (211) and second electrode lines (212) that intersect and are electrically connected with one another. Each second touch electrode chain (300) comprises multiple second electrode units (310) consisting of third electrode lines (311) and fourth electrode lines (312) that intersect and are electrically connected with one another. In the touch display panel, intersections only occur at the touch electrode chains, and thus there are fewer intersecting points, and the electrode lines are arranged in the electrode unit such that the touch display panel is more bendable.
D: A touch screen, a manufacturing method thereof, and a display apparatus. The touch screen comprises: an opposite substrate (1), an array substrate (2), and a liquid crystal layer (3) between the opposite substrate (1) and the array substrate (2), black matrices (4) being provided on a surface of the opposite substrate (1) facing the liquid crystal layer (3). The touch screen further comprises: a first touch electrode (5), an insulation layer (6), and a second touch electrode (7) that are sequentially disposed in a stacked manner on the surface of the opposite substrate (1) opposite to the liquid crystal layer (3). The first touch electrode (5) and the second touch electrode (7) are respectively located in an area corresponding to the black matrices (4). The first touch electrode (5) comprises multiple first touch sub-electrodes (51) distributed along a first direction. The second touch electrode (7) comprises multiple second touch sub-electrodes (71) distributed along a second direction perpendicular to the first direction. Because the first touch electrode (5) and the second touch electrode (7) are located on the surface of the opposite substrate (1) opposite to the liquid crystal layer (3) and are located in the area corresponding to the black matrices (4), not only light reflection and light absorption can be reduced to improve light transmittance, but also the adhesion precision and the product yield can be improved.
