The color film substrate and the display panel provided by the application are low in manufacturing cost and thin in thickness, the touch function is independent of the matching of the array substrate 600, and the use is more flexible.
As shown in fig. 1 to fig. 4, in the embodiment of the color film substrate proposed in the present application, the color film substrate includes a substrate layer 400, a color film layer 300, and an indium tin oxide layer 100 that are stacked. Wherein the indium tin oxide layer 100 includes: and the signal input end of the single-layer touch electrode pattern is used for being connected with the driving chip so as to enable the single-layer touch electrode pattern to be coupled to form a coupling capacitor.
The signal input end of the single-layer touch electrode pattern is used for being connected with a driving chip on the indium tin oxide layer 100 of the color film substrate, and after the driving chip inputs a driving signal to the single-layer touch electrode pattern, the single-layer touch electrode pattern is coupled to form a coupling capacitor.
The single-layer touch electrode pattern may be formed simultaneously in a photomask process of etching to form the indium tin oxide layer 100 pattern, where the indium tin oxide layer 100 pattern includes a single-layer touch electrode pattern and other functional electrode patterns, and the other functional electrode patterns may be a common electrode pattern or a shielding electrode pattern, and the single-layer touch electrode pattern is spaced from the other functional electrode patterns.
The driving chip may be directly connected to the signal input end of the single-layer touch electrode pattern in the binding area 220 on the color film substrate, and the end portion of the driving chip, which is used to connect the signal input end of the single-layer touch electrode pattern, and the end portion, which is connected to the array substrate 600, may be different output ends, and the driving chip may input the same or different driving signals to the single-layer touch electrode pattern as the array substrate 600.
The single-layer touch electrode pattern may be disposed in the display area 210 of the color film substrate, or the single-layer touch electrode pattern may be disposed outside the display area 210 of the color film substrate.
The color film substrate can be a color film substrate in various display panels such as a VA display panel, an IPS display panel, an HFFS display panel and the like.
As shown in fig. 3, in the VA display panel, the indium tin oxide layer 100 is a common electrode layer, and other functional electrode patterns are common electrode patterns, and are matched with the array substrate 600 to have an alignment function.
As shown in fig. 4, in the IPS display panel and the HFFS display panel, the indium tin oxide layer 100 is a back surface indium tin oxide layer 100, and other functional electrode patterns are shielding electrode patterns, which have a function of shielding external interference signals. The lamination relationship of the substrate layer 400, the color film layer 300 and the indium tin oxide layer 100 is determined according to the type of display panel, and is the same as that in the related art, for example, in the VA display panel, the color film layer 300 is between the substrate layer 400 and the indium tin oxide layer 100, and in the IPS display panel and the HFFS display panel, the substrate layer 400 is between the color film layer 300 and the indium tin oxide layer 100.

In addition, manufacturing a touch electrode layer can increase the process, cost and thickness of the display panel. When the electrode layers on the array substrate 600 side are matched, a driving signal fed into the touch electrode is also required to be transmitted through the wiring on the array substrate 600 side, so that during manufacturing, the array substrate 600 side is required to be modified, the manufacturing cost and the working procedure are increased, the number of layers of the display panel is increased easily, and the thickness of the final display panel is increased; during assembly, the problem of matching of the touch electrode also needs to be considered, the assembly is complex, and the accuracy requirement is higher; after the color film substrate and the array substrate 600 are disassembled, the touch function is lost, so that the maintenance, detection and other work are inconvenient; in addition, the touch electrode is driven by the driving signal passing through the array substrate 600 side, and the driving signal is limited to the driving signal supplied to the touch electrode because the driving signal needs to consider the operation of the array substrate 600 side, and the flexibility of the driving signal input is poor.
In the above embodiment, the single-layer touch electrode pattern is formed on the indium tin oxide layer 100, and the touch function is integrated on the indium tin oxide layer 100 while the original functions (such as alignment function and function of shielding external interference signals) of the indium tin oxide layer 100 are maintained, so that the pattern of the indium tin oxide layer 100 including the single-layer touch electrode pattern is formed once through the original photomask manufacturing process of the indium tin oxide layer 100 when the color film substrate is manufactured, without adding a new process, thereby saving cost and having simple process; the number of layers of the color film substrate is not increased, and the thickness of the color film substrate is unchanged; in addition, on the basis of the beneficial effects, the signal input end of the formed single-layer touch electrode pattern is connected with the driving chip on the color film substrate, the coupling capacitor can be directly formed without being matched with the side of the array substrate 600, and the touch function is independent of the array substrate 600; during assembly, the procedure of matching the touch electrode with the array substrate 600 can be saved, and the assembly is simpler; when the touch function is needed for maintenance, detection or other conditions, the touch operation can be performed only by connecting the color film substrate with the driving chip without matching the side of the array substrate 600; when the panel is used, the limit of driving signals supplied to the single-layer touch electrode pattern is small, the situation of the array substrate 600 matched with the single-layer touch electrode pattern is not needed to be considered, and the panel is more flexible to use.
