Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
The inventor analyses found that the reason that the touch sensitivity of the touch panel in the related art is unstable is related to the fluctuation of the resistance value of the Black Matrix (BM) on the color film substrate, and when the content of the C element in the BM fluctuates due to the presence of the C element in the BM material, the BM resistance value also fluctuates. If the content of the C element in the BM is too high, the resistance of the BM is reduced, referring to fig. 1, the BM forms a coupling capacitor C1 with the metal signal line such as the ground GND or GOA (gate on array) around the effective display area of the array substrate, and the BM forms a coupling capacitor C3 with the common electrode (sensor block) of the effective display area.
When the BM resistance is lower, the capacitance of the coupling capacitor C1 is larger, and when the voltage on metal signal wires such as GND or GOA changes, the voltage on the BM is influenced by the coupling capacitor C1, and then the voltage on a sensor block is influenced by the coupling capacitor C3, so that the voltage noise of the sensor block is caused; in addition, C0 in fig. 1 is a mutual capacitance/self capacitance of SLOC/TDDI Sensor, C2 is a capacitance formed by a finger touch Panel, when a finger touches the touch Panel, C2 is connected in series with n pieces of C3, a voltage change differΔc=c3×c2/(nc3+c2), the lower the BM resistance value is, the larger the n is, the smaller the voltage change differΔc is, and a scribing defect is caused. In summary, when the BM resistance is low, the poor touch such as voltage noise of the sensor block and poor scribing will be caused, which affects the stability of the touch sensitivity.
In order to solve the above-mentioned problems, an embodiment of the present application provides a touch panel, and referring to fig. 2, the touch panel includes a first substrate 21 and a second substrate 22.
The first substrate 21 includes a first substrate 211 and a touch signal line 212 disposed on a side of the first substrate 211 near the second substrate 22; the second substrate 22 includes a second substrate 221, a light shielding layer 222 and an electrode layer 223 stacked on the second substrate 221, the electrode layer 223 being disposed close to the first substrate 21; the electrode layer 223 has the same voltage as the touch signal line 212.
The touch panel provided in this embodiment may be a self-capacitance type touch panel or a mutual capacitance type touch panel. When the touch panel is a mutual capacitive touch panel, the touch signal line 212 may be a touch driving signal line Tx or a touch sensing signal line Rx.
In practical applications, the second substrate 22 may be a color film substrate, and the second substrate 22 may further include: the color resist layer RGB, the flat layer OC, and the spacer layer PS provided on the electrode layer 223 are stacked, and the color resist layer RGB is provided near the electrode layer 223. The light shielding layer 222 may be a black matrix BM on the color film substrate, and the front projection of the light shielding layer 222 on the first substrate 21 can cover the metal lines such as the touch driving signal lines Tx and the Data lines Data on the first substrate 21.
The first substrate 21 may be an array substrate, including an effective display area and a peripheral area, and the peripheral area is provided with metal signal lines such as GND and GOA.
There are various ways of realizing the same voltage of the electrode layer 223 and the touch signal line 212, for example, by connecting the electrode layer 223 with the touch signal line 212, or connecting the electrode layer 223 with a signal input terminal of the touch signal line 212, or the like.
Since the voltages of the electrode layer 223 and the touch signal line 212 are the same, that is, the voltages of the electrode layer 223 and the touch signal line 212 are kept uniform at the same time, and the electrode layer 223 is in contact with the light shielding layer 222, the voltages of the light shielding layer 222 and the touch signal line 212 are kept uniform at the same time. When the resistance of the light shielding layer 222 decreases, a peripheral coupling capacitor is formed between the light shielding layer 222 and the metal signal line in the peripheral region of the first substrate 21, and since the voltage of the light shielding layer 222 is consistent with the voltage of the touch signal line 212, the light shielding layer 222 cannot form a coupling capacitor with the touch signal line 212 or a common electrode (sensor block) connected with the touch signal line 212, and the like, even if the resistance of the light shielding layer 222 fluctuates, the touch sensitivity can be kept stable, the problem of decreasing the touch sensitivity such as poor scribing is solved, and in addition, the influence of the voltage fluctuation of the peripheral metal signal line on the voltage of the touch signal line 212 or the common electrode can be shielded, thereby eliminating voltage noise.
The embodiment provides a touch panel, since the voltages of the electrode layer and the touch signal line are the same, so that the voltages of the light shielding layer directly contacted with the electrode layer and the touch signal line are the same, no matter how the resistance value of the light shielding layer changes, the light shielding layer cannot form a coupling capacitor with the touch signal line on the first substrate or a common electrode connected with the touch signal line, so that poor touch caused by the influence of voltage fluctuation of the light shielding layer on the voltage of the touch signal line or the common electrode is avoided, the touch sensitivity can be still maintained under the condition that the resistance value of the light shielding layer fluctuates, and the stability of the touch sensitivity is improved.
In one implementation of the present embodiment, the touch panel includes a display area and a non-display area, and the electrode layer 223 is connected to the signal input end of the touch signal line 212 through silver paste in the non-display area 223.
Specifically, the electrode layer 223 is connected to the signal input end of the touch signal line 212 on the first substrate 21 through silver paste in the non-display area, so that the voltage on the electrode layer 223 is the same as the voltage of the touch signal line 212. The signal input end of the Touch signal line 212 may be disposed on a Touch chip Touch IC.
In order not to lose the aperture ratio, the orthographic projection of the electrode layer 223 on the second substrate 221 is smaller than or equal to the orthographic projection of the light shielding layer 222 on the second substrate 221.
Further, the front projection of the electrode layer 223 on the second substrate 221 may completely overlap with the front projection of the light shielding layer 222 on the second substrate 221, that is, the pattern (pattern) of the electrode layer 223 is completely the same as the pattern of the light shielding layer 222, and in a specific implementation, a mask of the light shielding layer 222 may be used in the process of manufacturing the electrode layer 223.
In a specific implementation, the touch signals on the touch signal line 212 (e.g., the touch driving signal line Tx) are sequentially sent in a touch signal period, that is, the signal input end of the touch signal line 212 sends the touch signals to the touch signal line 212 or the electrode layer 223 according to the touch signal period, and since the pattern of the electrode layer 223 is made of the mask of the light shielding layer 222, the periphery is connected together, and therefore, the voltage of the whole electrode layer 223 can be kept consistent with the voltage on any touch signal line 212 with the touch signal.
Since the orthographic projection of the electrode layer 223 on the second substrate 221 is completely covered by the orthographic projection of the light shielding layer 222 on the second substrate 221, the arrangement of the electrode layer 223 does not affect the liquid crystal display of the display area, and the arrangement of the electrode layer 223 does not cause a decrease in aperture ratio.
In order to improve the light transmittance, the electrode layer 223 may be a transparent electrode, such as ITO.
In practical applications, the first substrate 21 may further include: the passivation layer 213 and the common electrode layer 214 are disposed on the side of the touch signal line 212 near the second substrate 22, and the common electrode layer 214 is connected to the touch signal line 212 through a via hole disposed on the passivation layer 213.
In practical applications, a liquid crystal layer for controlling light transmittance may be further filled between the first substrate 21 and the second substrate 22, and in order to form an electric field for driving the liquid crystal to deflect, the first substrate 21 may further include an insulating layer 215 and a pixel electrode layer 216 disposed on the common electrode layer 214. The common electrode layer 214 and the pixel electrode layer 216 form an electric field driving the liquid crystal to deflect.
The present embodiment provides a touch panel capable of avoiding the touch sensitivity degradation caused by the fluctuation of the resistance of the light shielding layer 222. The touch panel is characterized in that an electrode layer 223 is arranged on a shading layer 222 of a color film substrate, the electrode layer 223 can be connected with a signal input end of a touch signal wire 212 on an array substrate through silver colloid, so that signals on the shading layer 222 and the touch signal wire 212 are kept consistent, and thus the shading layer 222 cannot generate coupling capacitance with the touch signal wire 212 or a common electrode layer 214 (sensor block), and therefore voltage fluctuation of peripheral metal signal wires is shielded to influence voltages of the touch signal wire 212 or a common electrode and the like, voltage noise and bad scribing are avoided, and stability of touch sensitivity is improved.
The application further provides a touch device, which may include the touch panel according to any one of the embodiments.
The embodiment provides a touch device, and since the touch device includes the touch panel described in any one of the embodiments, the specific structural improvement and the function are the same as those of the touch panel embodiment, and will not be repeated here.

Step 303: a second substrate is provided.
Step 304: and sequentially forming a shading layer and an electrode layer on the second substrate to obtain a second substrate.
Specifically, a mask plate of a light shielding layer can be utilized first, and a patterning process is adopted to form the light shielding layer on the second substrate; and then forming an electrode layer on the shading layer by using a composition process by using a shading layer mask.
The patterning process may include a series of film formation processes, such as film formation, exposure, development, etching, and the like.
In a specific implementation, an electrode layer material can be formed on the light shielding layer by adopting a sputtering dispenser process, and in the process of exposing the electrode layer material, a light shielding layer Mask BM Mask can be adopted for manufacturing, so that the same pattern as the light shielding layer can be obtained. Specifically, the first patterning process adopts a BM Mask to manufacture a BM Pattern, and the second patterning process also adopts the BM Mask to manufacture an electrode layer ITO Pattern. The ITO Pattern is manufactured later to facilitate the connection of the electrode layer with the signal input end of the touch signal line through silver colloid later.
In practical applications, the color resist layer RGB, the planarizing layer OC, and the spacer layer PS may be formed sequentially on the electrode layer.
