Embodiment 1
[0054] figure 1 It is a schematic diagram of a partial top view structure of an array substrate provided in Embodiment 1 of the present invention, the figure 1 One unit pixel region formed on the base substrate of the array substrate is shown. The one unit pixel area includes three sub-pixels, corresponding to the red, green, and blue (R, G, B) resins on the color filter substrate, which can be called red sub-pixels, green sub-pixels and blue sub-pixels respectively. sub-pixel. Specifically, the sub-pixels are formed by surrounding data lines and gate lines and arranged in a matrix. figure 1 Shown in the grid line Gn (one of the grid lines, may be called the first grid line), Gn-1 (one of the grid lines, located above the first grid line and adjacent to the first grid line, may be referred to as the second gate line). In addition, data lines Dr, Dg, and Db that respectively transmit data signals to the above three sub-pixels are also shown. A thin-film transistor (TFT) an...
Embodiment 2
[0066] Figure 5 It is a schematic flow chart of the manufacturing method of the array substrate provided in Embodiment 2 of the present invention. The array substrate in Embodiment 1 can be prepared by using the manufacturing method of the array substrate provided in Embodiment 2 to form a corresponding pattern structure. Such as Figure 5 As shown, the following steps of the method take four steps as an example, and each step includes processes such as deposition, coating, exposure, etching, and stripping; in specific implementation, each layer in the touch-sensitive pixel can be used for display Each layer in the sub-pixels is formed synchronously; and it is not limited to three photolithography, four photolithography or five photolithography processes, and those skilled in the art can choose to use. It can include:
[0067] Step 101, depositing a gate metal film on the substrate, and etching the gate metal film through a patterning process to form a pattern including a g...
Embodiment 3
[0080] Embodiments of the present invention also provide a color filter substrate, which may include red, green and blue resins, a black matrix and spacers.
[0081] Specifically, the black matrix includes a sensing area, the sensing area is arranged opposite to the touch sensing pixel area on the array substrate, and covers the touch sensing pixel area. The spacer may include a sub-spacer, the first end of the sub-spacer is adjacent to the black matrix, and the second end of the sub-spacer is opposite to, but not in contact with, the sensing thin film transistor and the capacitor.
[0082] Further, a reflective layer may be provided on the surface of the second end of the sub-spacer, and the reflective layer may be used to reflect light from a backlight source to the sensing thin film transistor. The reflective layer can be copper or aluminum.
[0083] The improvement of the structure of the sub-spacer can be separately described in detail below. The sub-spacer can be arrang...
