The color film substrate and the display panel provided by the application are low in manufacturing cost and thin in thickness, the touch function does not depend on the matching of the array substrate 600, and the use is more flexible.
As shown in fig. 1 to 4, in an embodiment of the color filter substrate provided in the present application, the color filter substrate includes a substrate layer 400, a color film layer 300, and an ito layer 100 that are stacked. Wherein the ito 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 couple the single-layer touch electrode pattern 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 can be formed synchronously in a photomask manufacturing process for forming the indium tin oxide layer 100 pattern through etching, the indium tin oxide layer 100 pattern comprises the single-layer touch electrode pattern and other functional electrode patterns, the other functional electrode patterns can be common electrode patterns or shielding electrode patterns, and the single-layer touch electrode pattern and the other functional electrode patterns are arranged at intervals.
The driving chip may be directly connected to the signal input end of the single-layer touch electrode pattern in the bonding region 220 on the color film substrate, the end of the driving chip used for connecting the signal input end of the single-layer touch electrode pattern and the end connected to the array substrate 600 may be different output ends, and the driving chip may input the same or different driving signals as those of the array substrate 600 to the single-layer touch electrode pattern.
The single-layer touch electrode pattern may be disposed in the display region 210 of the color filter substrate, or the single-layer touch electrode pattern may be disposed outside the display region 210 of the color filter 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, a HFFS display panel and the like.
As shown in fig. 3, in the VA display panel, the ito layer 100 is a common electrode layer, and the other functional electrode patterns are common electrode patterns, and cooperate 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 ito layer 100 is a rear ito layer 100, and the other functional electrode patterns are shielding electrode patterns, which have a function of shielding external interference signals. The stacking relationship of the substrate layer 400, the color film layer 300 and the ito layer 100 depends on the type of the display panel, and is the same as the stacking relationship in the prior art, such as VA display panel in which the color film layer 300 is between the substrate layer 400 and the ito layer 100, and IPS display panel and HFFS display panel in which the substrate layer 400 is between the color film layer 300 and the ito layer 100.
In the prior art, an ito layer 100 is formed on a color film substrate of a display panel, patterns of the ito layer 100 on the ito layer 100 have alignment and shielding functions, and an additional touch electrode layer needs to be manufactured or needs to be matched with an electrode layer on the side of the array substrate 600 to realize a touch function. In addition, the manufacturing of a touch electrode layer will increase the process, cost and thickness of the display panel. When the electrode layer on the side of the array substrate 600 is matched, the driving signal supplied to the touch electrode also needs to be transmitted through the routing on the side of the array substrate 600, so that in manufacturing, the side of the array substrate 600 needs to be modified, the manufacturing cost and the process are increased, the number of layers of the display panel is increased easily, and the final thickness of the display panel is increased; during assembly, the matching problem of the touch electrode also needs to be considered, the assembly is complex, and the requirement on accuracy is higher; after the color film substrate and the array substrate 600 are detached, the touch function is lost, which causes inconvenience in maintenance, detection and other work; in addition, since the touch electrodes are driven by the driving signal passing through the array substrate 600 side, the driving signal needs to be considered in the operation of the array substrate 600 side, the driving signal supplied to the touch electrodes is limited more, and the flexibility of inputting the driving signal is poor.
In the above embodiment, a single-layer touch electrode pattern is formed on the ito layer 100, and while the original functions (such as alignment function and external interference signal shielding function) of the ito layer 100 are maintained, the ito layer 100 integrates a touch function, and when a color filter substrate is manufactured, the ito layer 100 pattern including the single-layer touch electrode pattern is formed at one time by the original mask process for manufacturing the ito layer 100, and thus, no new process is required to be added, the cost is saved, and the process is simple; the number of layers of the color film substrate is not increased, and the thickness of the color film substrate is not changed; 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, and can directly form a coupling capacitor without being matched with the side of the array substrate 600, and the touch function does not depend on the array substrate 600; during assembly, the working 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 in maintenance, detection or other situations, the touch operation can be performed only by connecting the color film substrate with the driving chip without the side matching of the array substrate 600; when the panel is used, the limitation of the driving signal 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 does not need to be considered, and the panel is more flexible to use.
As a further solution of the above embodiment, the single-layer touch electrode pattern is a single-layer multi-touch electrode pattern, and has a plurality of touch electrode units 110, all the touch electrode units 110 are located on the ito layer 100, and signal input terminals of all the touch electrode units 110 are used for connecting with a driving chip, so that the touch electrode units 110 are coupled to form a coupling capacitor unit. After the driving chip inputs a driving signal to each touch electrode unit 110, each touch electrode unit 110 is coupled to itself to form a coupling capacitor unit.
The touch electrode units 110 may be disposed in the display region 210 of the color filter substrate.
The other functional electrode patterns include a plurality of other functional electrode units 120, the other functional electrode units 120 are alternately arranged with the touch electrode unit 110, and the other functional electrode units 120 are used for implementing functions such as alignment, shielding, and the like.
In a further aspect of the foregoing embodiment, multi-point touch can be implemented on the color film substrate, and more diversified operations can be performed.
Of course, the single-layer touch electrode pattern may also be a single-point touch type touch electrode pattern.
As a further solution of the above embodiment, the single-layer touch electrode pattern is a single-layer multi-point mutual capacitance touch electrode pattern, and the touch electrode unit 110 includes: a driving electrode unit 111 and a sensing electrode unit 112; the driving electrode unit 111 is located on the ito layer 100, and a signal input end thereof is used for being connected with a first output end of the driving chip; the sensing electrode unit 112 is located on the ito layer 100, and is disposed corresponding to the driving electrode unit 111, and a signal input end of the sensing electrode unit is used for being connected to a second output end of the driving chip, so that the driving electrode unit 111 and the sensing electrode unit 112 are coupled to form a coupling capacitor unit.
The first output terminal and the second output terminal of the driving chip are not used for being connected with the array substrate 600.
In a further scheme of the above embodiment, the driving chip inputs driving signals to the driving electrode unit 111 and the sensing electrode unit 112 through the first output terminal and the second output terminal, respectively, and a mutual capacitance type capacitor is formed between the driving electrode unit 111 and the sensing electrode unit 112, so that multi-contact touch can be performed, and a better touch effect can be achieved.
Of course, the single-layer touch electrode pattern may also be a self-contained touch electrode pattern.

In a further aspect of the foregoing embodiment, the first tooth-shaped structure 114 and the second tooth-shaped structure 115 are staggered to form a more uniform coupling electric field, so as to improve the touch effect.
As a further solution to the above embodiment, each touch electrode unit 110 is connected to a lead wire 113, and the signal input end of the touch electrode unit 110 is used for being connected to the driving chip through the connected lead wire 113.
