Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.

"upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed description of known functions and known components.
The embodiment of the disclosure provides a touch panel, the schematic diagram of which is shown in fig. 1, including:
The touch control device comprises a touch control contact layer 1, a touch control graph layer 2 corresponding to the touch control contact layer, a touch control wiring layer 3 connected with the touch control graph layer 2 and a connecting pin 4 connected with each touch control wiring Rx, wherein the touch control contact layer 1 and the touch control graph layer 2 jointly act to generate a capacitance value used for determining a touch point under the condition of receiving touch control operation, each touch control wiring Rx is connected with a plurality of patterns 21 (patterns) in the touch control graph layer 2, the plurality of patterns 21 connected with each touch control wiring Rx have different maximum capacitance values relative to the touch control contact layer 1, and each touch control wiring Rx is connected with one connecting pin 4.
According to the embodiment of the disclosure, the touch capacitor is designed, and the touch patterns in the touch graphic layer relative to the touch contact layer are designed in different capacitances, so that the same touch wiring can be connected with a plurality of patterns, the number of the touch wirings is reduced, the design of the existing narrow frame is met, the problem of touch delay is avoided, and the system performance is improved.
In particular, in order to make each pattern have different maximum capacitance values with respect to the touch contact layer, the patterns may be set to have the same touch area or different touch areas when designing the patterns, which will be described below.
Fig. 2 is a schematic diagram of pattern arrangement in the prior art, for SLOC (SINGLE LAYER on Cell, i.e. a single layer pattern on glass, a technology called oncell touch technology, in which an ITO pattern is formed on CF glass in a single layer bridging manner), one Tx signal corresponds to multiple Rx signals (i.e. touch traces), tx sends out signals, rx receives signals in sequence, and the pattern position corresponding to the Rx signal with the largest signal variation is the touch position. As can be seen from the figure, each pattern is connected with one touch trace, and the touch traces occupy a larger arrangement area.
When the touch graphic layer includes multiple patterns with the same touch area, as shown in fig. 3, which is a schematic diagram of pattern arrangement in an embodiment of the disclosure, it can be seen that, because two patterns connected with each touch trace have different maximum capacitance values relative to the touch contact layer, one touch trace can be connected with two patterns at the same time.
Fig. 3 is only one possible arrangement, and a person skilled in the art may change the arrangement, for example, divide the touch graphic layer into a plurality of partitions, the height values of the patterns in each partition relative to the touch contact layer are the same, the height values of each partition relative to the touch contact layer are different, as shown in fig. 4, the maximum capacitance value of the pattern corresponding to the upper half of the touch panel is set to be the first capacitance value, and the maximum capacitance value of the pattern corresponding to the lower half of the touch panel is set to be the second capacitance value. Of course, fig. 3 is only an example, and one touch trace may be connected to more patterns at the same time, as long as the connected patterns have different maximum capacitance values.
In this embodiment, the touch patterns are square, and in the patterns of the touch pattern layer in fig. 3 or fig. 4, each pattern connected by each touch trace has a different height value relative to the touch contact layer, so as to achieve the effect of having different maximum capacitance values relative to the touch contact layer. Under the condition that the touch areas are the same, different height values can be realized by (1) processing the substrate, namely, high and low substrate layers with different thicknesses and patterns with the same thickness respectively arranged at the high and low parts of the high and low substrate layers, (2) not processing the substrate, namely, the substrate layers with the same thickness and the patterns with different thicknesses arranged on the substrate layers.
By means of substrate processing, two patterns can be different in height, one touch trace is used for being connected to two areas with different heights, and due to the difference in pattern height, capacitance difference between different positions of fingers in touch scanning is large, and two touch patterns can be distinguished by the same touch trace according to the difference in touch capacitance, as shown in fig. 5. The mode can reduce the touch control wiring to the original half, and the reduced touch control wiring is more due to different height differences.
The two patterns may be different in height without processing the substrate, and as shown in fig. 6, different touch pattern heights may be achieved by making different patterns into different thicknesses.
For TDDI (Touch and display driver Integration), TDDI is to combine the display layer and the Touch layer, and display and Touch are performed simultaneously by using the same IC chip, which can save the Touch IC chip, but too many Touch pins (connection pins) can cause cost increase, as shown in fig. 7, the conventional TDDI Touch mode divides different Touch areas into a plurality of independent Touch patterns, and each Touch pattern is connected to the display IC chip through a Touch trace, so that the number of Touch traces is more.
As shown in fig. 8, which is a schematic diagram of pattern arrangement of TDDI touch manner provided in the embodiment of the disclosure, different areas are set to have different touch pattern heights, for example, a conventional scheme adopts a single ITO2 as a touch pattern, a new scheme adopts ITO1& ITO2 (i.e., two patterns) as the touch pattern, and the ITO1& ITO2 patterns are simultaneously connected to one touch trace, so that the touch trace can be reduced to 1/2, and similarly, the touch trace can be reduced to 1/3 by adopting ITO1& ITO2& ITO3 traces.
Of course, the above figures of the embodiments of the disclosure are only examples, the patterns are not necessarily square, and those skilled in the art can design surface area shapes of different shapes for the patterns, as long as the touch areas are the same.
When the touch graphic layer includes multiple patterns with different touch areas, each pattern may have the same height value with respect to the touch contact layer. As shown in fig. 9, which is a schematic diagram of pattern arrangement in the embodiment of the disclosure, it can be seen that, since two patterns connected to each touch trace have different touch areas with respect to the touch contact layer, the maximum capacitance value is different, and therefore, one touch trace can be connected to two patterns at the same time.
In fig. 9, one touch trace is simultaneously connected to three patterns with different touch areas, namely, upper, middle and lower, and the touch patterns are distinguished according to the difference of touch capacitance during touch scanning due to the difference of pattern sizes. Thus, the touch wiring can be reduced to one third of the original one.
The patterns with different touch areas can also be shown in fig. 10, and the touch patterns in adjacent areas are made into hollowed-out shapes so as to obtain three touch patterns with different touch areas, so that the touch signal amounts in the touch of different areas are different. Of course, as shown in fig. 11, the adjacent touch patterns may be formed into special-shaped patterns with different areas, which can be set by those skilled in the art according to actual requirements.
In order to enable one touch trace to be connected with more patterns, the touch graphic layer can be designed to have multiple patterns with different touch areas, and each pattern can also have different height values relative to the touch contact layer.
According to the embodiment of the disclosure, the touch control wiring is reduced, the wiring frame is saved, the wiring can be wider on the premise of the same frame, more space is provided for peripheral GND (antistatic wiring) and other wiring, the occurrence of ESD (electrostatic discharge) faults is reduced, the touch control wiring frame is narrower on the premise of the same line width, the number of touch control bonding pins is reduced, the space is saved, the cost of a touch control module is saved, the scheme is simple, additional technology is not increased, additional cost is not increased, and the implementation is strong.
The embodiment of the disclosure also provides a display screen, which at least comprises the touch panel in the embodiment.
The embodiment of the disclosure also provides electronic equipment, which at least comprises the display screen. Of course, the touch control device also comprises an IC chip connected with each connecting pin and used for receiving one or more capacitance values and determining touch control points according to the one or more capacitance values, wherein the IC chip also has a display processing function, and a control line connected with the IC chip through the connecting pins and used for sending control signals.
The touch pattern design disclosed by the embodiment of the disclosure adopts the touch patterns with different heights at different positions, and uses the same touch trace to control when the patterns with different heights are touched, so that the purpose of scanning the touch positions by using fewer touch traces is achieved, the touch frame can be reduced, the number of the touch traces is reduced, the touch bonding pins (connecting pins) are reduced, and the touch point reporting rate is improved.
