Abstract
Description
BACKGROUND
[0001] With the rapid development of display technology, touch-controlled displays have found widespread application in numerous areas and industries of modern society. Current touch-controlled display panels are often divided into various categories, such as resistive touch-controlled displays, capacitive touch-controlled displays, acoustic surface wave capacitive touch-controlled displays, and optical imaging capacitive touch-controlled displays, among others. Compared to a resistive touch-controlled display, a capacitive touch-controlled display offers advantages such as a long lifespan, high transmission, and multi-touch capability, making it an attractive area within touch-controlled display technology.
[0002] The touch control detection principle of the capacitive touch control array is explained as follows. Overlapping touch control drive electrodes and touch control sensing electrodes are arranged in the touch control display array, with multiple interfaces formed between the drive electrodes and sensing electrodes. A capacitor array is formed at these interfaces. A driver chip supplies a touch control detection signal to each drive electrode and sequentially detects a touch control sensing signal from the corresponding sensing electrode. When a change in capacitance is detected, a corresponding touch position is identified.
[0003] Because the touch control electrodes are often located at different positions within the touch control display area, each touch control signal line can have a different length. Consequently, the total resistance of each touch control electrode, plus the electrically connected touch control signal line, can vary. Due to this varying total resistance, the touch control signals output by different touch control signal lines can exhibit different time delays when the touch control electrode outputs a signal via the electrically connected touch control signal line. As a result, the uniformity of touch control sensitivity across the entire touch control display area can be poor.

DETAILED DESCRIPTION
[0014] Exemplary embodiments of the invention, illustrated in the accompanying drawings, will now be discussed in detail. Embodiments consistent with the disclosure are subsequently described with reference to the drawings. Where possible, the same reference numerals are used in all drawings to denote identical or similar parts. It is obvious that the described embodiments are some, but not all, embodiments of the present invention. A person skilled in the art may derive further embodiments consistent with the present disclosure, all of which fall within the scope of the present invention, from the disclosed embodiments. Furthermore, the embodiments described in the present disclosure and the features of the described embodiments can be combined without conflict under certain conditions.
[0015] The present invention provides an improved touch control display panel comprising multiple touch control actuator electrodes, multiple touch control sensing electrodes, and a first integrated circuit. The touch control actuator electrodes can include multiple first touch control sensing electrodes and multiple second touch control sensing electrodes. The distance between the first touch control sensing electrode and the first integrated circuit can be greater than the distance between the second touch control sensing electrode and the first integrated circuit.
[0016] The total resistance of the first touch control measuring electrode and the first touch control measuring signal line electrically connected to the first touch control measuring electrode is R1, and the total resistance of the second touch control measuring electrode and the second touch control measuring signal line electrically connected to the second touch control measuring electrode is R2. R1 and R2 can satisfy a predetermined relationship such that touch control measuring signals output by each touch control measuring signal line have substantially the same signal delay time.
[0017] Fig. Figure 1A shows a top view of an exemplary touch control display panel according to the disclosed embodiments. As shown in Fig. As shown in Figure 1A, the touch control display panel 100 can comprise multiple touch control drive electrodes 101, multiple touch control measuring electrodes 103, multiple touch control measuring signal lines 104, and a first integrated circuit 105. The first integrated circuit 105 can be any suitable display control circuit and / or touch sensing circuit and / or touch measuring circuit of the touch control display panel.
[0018] The touch control display panel 100 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display panel, a plasma display panel (PDP), a field emission display (FED), a light-emitting diode (LED) display panel, a quantum dot (QD) display panel, an electrophoretic display panel, or any other suitable display panel capable of displaying videos and / or images.
[0019] In the touch control display field 100, the touch control actuator electrodes 101 can extend in a first direction D1 and be arranged in a second direction D2. The first direction D1 can intersect the direction D2. As shown in Fig. As shown in Figure 1A, the touch control display field 100 can include several touch control measuring electrodes 103, for example, a touch control measuring electrode RX1, a touch control measuring electrode RX2, etc. The touch control measuring electrodes 103 can extend in the second direction D2 and be arranged in the first direction D1.
[0020] The touch control actuator electrode 101 and the touch control measuring electrode 103 can have different shapes depending on the application scenario. In one embodiment, as shown in Fig. As shown in Figure 1A, the touch control actuator electrode 101 and the touch control measuring electrode 103 are each strip-shaped electrodes. That is, the strip-shaped touch control actuator electrodes 101 can extend in the first direction D1 and be arranged in the second direction D2. Meanwhile, the strip-shaped touch control measuring electrodes 103 can extend in the second direction D2 and be arranged in the first direction D1.
[0021] In another embodiment, the touch control actuator electrode 101 and the touch control measuring electrode 103 can differ from the strip-shaped electrode; for example, the touch control actuator electrode 101 and / or the touch control measuring electrode 103 can be a zigzag electrode, a wave-shaped electrode, etc. Number and shape of the touch control electrodes in Fig. 1A serves only for illustration and is not intended to limit the scope of this disclosure.
[0022] The first integrated circuit 105 can include a driver chip, and each touch control measuring electrode 103 can be electrically connected to the first integrated circuit 105 via a corresponding touch control measuring signal line 104. The multiple touch control measuring electrodes 103 can include multiple first touch control measuring electrodes and multiple second touch control measuring electrodes. The touch control measuring signal lines 104 can include multiple first touch control measuring signal lines and multiple second touch control measuring signal lines.
[0023] Specifically, the first touch control measuring electrode can be electrically connected to the first integrated circuit 105 via a corresponding first touch control measuring signal line. The second touch control measuring electrode can also be electrically connected to the first integrated circuit 105 via a corresponding second touch control measuring signal line. The distance between the first touch control measuring electrode and the first integrated circuit 105 can be greater than the distance between the second touch control measuring electrode and the first integrated circuit 105.
[0024] For example, as in Fig. Figure 1A shows that the distance from the touch control measuring electrode RX1 to the first integrated circuit 105 can be greater than the distance from the touch control measuring electrode RX2 to the first integrated circuit 105, where the touch control measuring electrode RX1 can be referred to as the first touch control measuring electrode, while the touch control measuring electrode RX2 can be referred to as the second touch control measuring electrode. Conversely, the distance from the touch control measuring electrode RX2 to the first integrated circuit 105 can be greater than the distance from the touch control measuring electrode RX3 to the first integrated circuit 105, where the touch control measuring electrode RX2 can be referred to as the first touch control measuring electrode, while the touch control measuring electrode RX3 can be referred to as the second touch control measuring electrode.
[0025] It should be noted that the first touch control measuring electrode and the second touch control measuring electrode do not refer to a specific touch control measuring electrode or electrodes. Instead, the first touch control measuring electrode and the second touch control measuring electrode can represent a relative concept. For example, if there are two touch control measuring electrodes, according to their different distances from the first integrated circuit 105, one of the two touch control measuring electrodes can be considered the first touch control measuring electrode and the other the second touch control measuring electrode.
[0026] In the disclosed embodiments, each touch control measuring electrode 103 and each touch control measuring signal line 104 can each have a specific resistance. Suppose the total resistance of the first touch control measuring electrode and the associated first touch control measuring signal line electrically connected to the first touch control measuring electrode is R1, and the total resistance of the second touch control measuring electrode and the associated second touch control measuring signal line electrically connected to the second touch control measuring electrode is R2.
[0027] In the disclosed embodiments, the resistors R1 and R2 can be configured to satisfy a predetermined relationship such that the total resistance of each touch control measuring electrode and its electrically connected touch control measurement signal line can be equal or substantially equal. The touch control measurement signals output via the first touch control measurement signal line and the second touch control measurement signal line, respectively, have substantially the same signal delay. Consequently, the uniformity of the touch control sensitivity across the entire touch control display area can be improved.
[0028] In one embodiment, the resistors R1 and R2 can be configured to satisfy a predetermined relationship -20% ≤ (R1 - R2) / R2 ≤ 20%, such that the detected touch control measurement signals output via the first touch control measurement signal line and the second touch control measurement signal line can have substantially the same signal delay. This means that in the touch control display field 100, the uniformity of the touch control sensitivity across the entire touch control display field 100 can be improved if the total resistance of each touch control measurement electrode 103 and the associated touch control measurement signal line 104 electrically connected to the touch control measurement electrode 103 is equal or substantially equal.
[0029] In certain embodiments, the resistance R1 can be equal to R2. This means that the total resistance R1 of the first touch control measuring electrode and the first touch control signal line electrically connected to the first touch control measuring electrode can be equal to the total resistance R2 of the second touch control measuring electrode and the second touch control signal line electrically connected to the second touch control measuring electrode. Accordingly, in the touch control display field 100, the total resistance of each touch control measuring electrode 103 and the associated touch control signal line 104 electrically connected to the touch control measuring electrode 103 can be the same. Thus, each touch detection point on the touch control display field 100 can have the same touch control sensitivity.
[0030] Furthermore, the resistance of each touch control measuring electrode 103 and / or the resistance of each touch control measuring signal line 104 can be changed by various approaches so that R1 and R2 can be configured to satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20%. Consequently, in the touch control display panel 100, the signal delay time can be essentially the same when the first touch control measuring electrode and the second touch control measuring electrode each send touch control measuring signals to the first integrated circuit 105. Thus, the uniformity of the touch control sensitivity can be improved across the entire touch control display panel 100.
[0031] As in Fig. As shown in Figure 1A, in the touch control display field 100, assuming an equal resistance of each touch control measuring electrode 103, the first touch control measuring lead and the second touch control measuring lead can have the same resistance or the same resistance within the permissible error range if the first touch control measuring lead electrically connected to the first touch control measuring electrode and the second touch control measuring lead electrically connected to the second touch control measuring electrode have the same lead width and the same length or within the permissible error range.
[0032] Thus, in the touch control display field 100, R1 and R2 can satisfy the condition -20%≤(R1-R2) / R2≤20% if the first touch control measuring electrode and the second touch control measuring electrode have the same resistance and, meanwhile, the first touch control measuring lead and the second touch control measuring lead have the same resistance or within the permissible error range.
[0033] Furthermore, an insulating layer can be arranged in the touch control display field 100 between the touch control measuring electrodes 103 and the touch control measuring signal lines 104. Several through-holes can be arranged in the insulating layer, as indicated by the black dots in Fig. 1A is designated. Each through-hole can correspond to a touch control measuring electrode 103, and each touch control measuring electrode 103 can be electrically connected to the touch control measuring signal line 104 through the corresponding through-hole.
[0034] In one embodiment, the first touch control measurement signal line and the second touch control measurement signal line can be permanently of the same length if the first touch control measurement signal line has a greater length than the second touch control measurement signal line in the first direction D1, by configuring the first touch control measurement signal line to have a shorter length than the second touch control measurement signal line in the second direction D2. This improves the uniformity of the touch control sensitivity across the entire touch control display field 100. An example is given in Fig. Shown in 1A.
[0035] As in Fig. As shown in Figure 1A, the first touch control measuring electrode can be designated as touch control measuring electrode RX1 and the second touch control measuring electrode as touch control measuring electrode RX2. The touch control measuring signal line 104 electrically connected to touch control measuring electrode RX1 can comprise a first part extending in the first direction D1 and a second part extending in the second direction D2, with lengths L2 and L1, respectively. This means that the touch control measuring signal line 104 electrically connected to touch control measuring electrode RX1 can be a folded line with multiple segments, and the multiple segments need not belong to the same straight line.
[0036] Similarly, the touch control measuring signal line 104, electrically connected to the touch control measuring electrode RX2, can comprise a first part extending in the first direction D1 and a second part extending in the second direction D2, with lengths L4 and L3 respectively. This means that the touch control measuring signal line 104, electrically connected to the touch control measuring electrode RX2, can also be a bent line with multiple segments.
[0037] In particular, L2 can be longer than L4. If L1 is configured shorter than L3 by adjusting the positions of the through-holes accordingly, L1, L2, L3, and L4 can be configured to essentially satisfy L1+L2=L3+L4. Consequently, the touch control sensitivity can be essentially uniform across the entire touch control display area 100.
[0038] Furthermore, as in Fig. As shown in Figure 1A, the projection of the touch control measuring signal line 104 onto the touch control measuring electrode 103 is a straight line. This means that the portion of the touch control measuring signal line 104 can have the projection of a straight line when projected onto the touch control measuring electrode 103 extending in the second direction D2.
[0039] In certain embodiments, the projection of the touch control measuring signal line 104 onto the touch control measuring electrode 103 can be a kinked line or a curve. That is, the portion of the touch control measuring signal line 104 can have the projection of a kinked line or curve when projected onto the touch control measuring electrode 103 extending in the second direction D2.
[0040] In the second touch control signal line, for example, the second part extending in the second direction D2 is a straight line, and consequently, the condition that the length of the second touch control signal line is the same as the length of the first touch control signal line cannot be met. However, the first part of the second touch control electrode can be configured to be a kinked line or curve, so that the length of the first part of the second touch control signal line can be extended. The length of the second touch control signal line can then be essentially the same as the length of the first touch control signal line. The corresponding structure is shown in Fig. 1B illustrates.
[0041] Fig. Figure 1B shows a top view of another exemplary touch control display panel according to the disclosed embodiments. The similarities between Fig. 1A and Fig. 1B will not be repeated here, although certain differences may be explained.
[0042] As in Fig. As shown in Figure 1B, the first touch control measuring electrode can be referred to as the touch control measuring electrode RX1 (referred to as RX1 in the following description), and the second touch control measuring electrode can be referred to as the touch control measuring electrode RX8 (referred to as RX8 in the following description). The touch control measuring signal line 104 electrically connected to RX1 can have a length L1. The touch control measuring signal line 104 electrically connected to RX8 can comprise a first part extending in the first direction D1 and a second part extending in the second direction D2, with lengths of L3 and (L2+L4), respectively.
[0043] If the second part is a straight line, i.e., if the second part only comprises segment L2, the length of the touch control measurement signal line 104 electrically connected to RX8 cannot be configured to be the same length as the touch control measurement signal line 104 electrically connected to RX1 by specifically designing the positions of the through-holes. That is, L2+L3≠L1. Specifically, (L2+L3) can be smaller than L1, i.e., L2+L3 <L1.
[0044] To solve the problem outlined above, as described in Fig. As shown in Figure 1B, the projection of the touch control measurement signal line 104, electrically connected to RX8, can be configured as a kinked line when projected onto RX8. This means that the projection of the second part of the touch control measurement signal line 104, electrically connected to RX8, can be configured as a kinked line, for example, including segments L3 and L4, when projected onto RX8. Thus, the length of the touch control measurement signal line 104, electrically connected to RX8, can be configured to be the same or substantially the same length as the touch control measurement signal line 104 electrically connected to RX1. That is, L2 + L3 + L4 = L1.
[0045] As discussed above, the disclosed touch control display panel 100 can comprise multiple first touch control measuring electrodes and multiple second touch control measuring electrodes. The distance between the first touch control measuring electrode and the first integrated circuit 105 can be greater than the distance between the second touch control measuring electrode and the first integrated circuit 105.
[0046] By configuring the length of the first touch control measurement signal lead electrically connected to the first touch control measurement electrode to be the same or substantially the same length as the second touch control measurement signal lead electrically connected to the second touch control measurement electrode, R1 can be equal to R2, or R1 can be equal to R2 within the permissible error range. R1 is the total resistance of a first touch control measurement electrode and the first touch control measurement signal lead electrically connected to the first touch control measurement electrode, and R2 is the total resistance of a second touch control measurement electrode and the second touch control measurement signal lead electrically connected to the second touch control measurement electrode.
[0047] Consequently, the total resistance of each touch control measuring electrode 103 and the touch control measuring signal line 104 electrically connected to the touch control measuring electrode 103 can be essentially the same. Accordingly, the uniformity of the touch control sensitivity across the entire touch control display field 100 can be improved.
[0048] Fig. Figure 2 shows a top view of another exemplary touch control display panel according to the disclosed embodiments. The similarities between Fig. 1A and Fig. Points 2 are not repeated here, while certain differences may be explained.
[0049] As in Fig. As shown in Figure 2, the touch control indicator panel 200 can comprise multiple touch control drive electrodes 201, multiple touch control sensing electrodes 203, multiple touch control sensing signal lines 204, and a first integrated circuit 205. The multiple touch control sensing electrodes 203 can comprise multiple first touch control sensing electrodes and multiple second touch control sensing electrodes. Each touch control sensing electrode 203 can be configured to have the same area and length in the first direction D1, so that the first touch control sensing electrode and the second touch control sensing electrode can have substantially the same resistance.
[0050] Provided that the first touch control measuring electrode and the second touch control measuring electrode have the same resistance, the total resistance of each touch control measuring electrode and the touch control measuring signal line electrically connected to the touch control measuring electrode can be substantially the same if the first touch control measuring signal line electrically connected to the first touch control measuring electrode has the same resistance as the touch control measuring signal line electrically connected to the second touch control measuring electrode.
[0051] This means that in the touch control display panel 200, the resistance R1 can be essentially equal to the resistance R2 if R1 is the total resistance of the first touch control measuring electrode and the first touch control measuring signal line electrically connected to the first touch control measuring electrode, and R2 is the total resistance of the second touch control measuring electrode and the second touch control measuring signal line electrically connected to the second touch control measuring electrode. Consequently, the touch detection points on the touch control display panel 200 can exhibit a more uniform touch control sensitivity.
[0052] To achieve the aforementioned goal, in one embodiment, as in Fig. Figure 2 shows that the first touch control signal line can be configured to have a greater length and width than the second touch control signal line, while the first touch control signal line can be configured to have the same length-to-width ratio as the second touch control signal line. Thus, the resistance of the first touch control signal line can be equal to the resistance of the second touch control signal line.
[0053] According to the resistance equation, the resistance of the touch control signal line 204 is related to its conductivity, length, and cross-sectional area. The touch control signal lines 204 in the touch control display field 200 are often realized by etching the same metal layer, so that each touch control signal line 204 in the same touch control display field can have the same conductivity and the same metal layer thickness. This means that the cross-sectional area of the touch control signal line 204 can only be related to its width.
[0054] Thus, the resistance of each touch control measurement signal line 204 can be determined from the length-to-width ratio of the touch control measurement signal line 204. If the first touch control measurement signal line has the same length-to-width ratio as the second touch control measurement signal line, R1 can be equal to R2. Consequently, each touch detection point on the touch control display panel 200 can have the same uniform touch control sensitivity. The corresponding structure can be found in Fig. 2 will be explained.
[0055] As in Fig. As shown in Figure 2, in one embodiment the first touch control measuring electrode and the second touch control measuring electrode can be designated as touch control measuring electrode RX1 (referred to as RX1 in the following description) and touch control measuring electrode RX2 (referred to as RX2 in the following description), respectively. Accordingly, the first touch control measuring signal line can be designated as the touch control measuring signal line electrically connected to RX1, and the second touch control measuring signal line can be designated as the touch control measuring signal line electrically connected to RX2.
[0056] Specifically, the touch control measurement signal line electrically connected to RX1 can have a length L1, and the touch control measurement signal line electrically connected to RX2 can have a length L2. The ratio between the length of the touch control measurement signal line electrically connected to RX1 and the length of the touch control measurement signal line electrically connected to RX2 can be L1:L2.
[0057] The touch control signal line electrically connected to RX1 can be longer than the touch control signal line electrically connected to RX2. Conversely, the touch control signal line electrically connected to RX1 can have a greater conductor width than the touch control signal line electrically connected to RX2. Specifically, the ratio between the conductor width of the touch control signal line electrically connected to RX1 and the conductor width of the touch control signal line electrically connected to RX2 can also be L1:L2. Thus, the touch control signal line electrically connected to RX1 can have the same length-to-conductor-width ratio as the touch control signal line electrically connected to RX2.
[0058] If the touch control signal line electrically connected to RX1 has the same length-to-width ratio as the touch control signal line electrically connected to RX2, then the touch control signal line connected to RX1 can have the same resistance as the touch control signal line connected to RX2. Consequently, each touch detection point on the touch control display panel 200 can have the same touch control sensitivity.
[0059] As in Fig. As shown in Figure 2, in the touch control display field 200, the length of the touch control signal line electrically connected to the corresponding touch control measuring electrode can gradually decrease in the first direction D1 as the distance from each touch control measuring electrode 203 to the first integrated circuit 205 decreases. Meanwhile, the width of the touch control signal line electrically connected to the corresponding touch control measuring electrode can also gradually decrease. However, since each touch control signal line can have the same length-to-width ratio, each touch control signal line can still have the same resistance. Consequently, each touch detection point on the touch control display field 200 can still have the same touch control sensitivity.
[0060] For example, the touch control signal line electrically connected to RX1 can have a length L1, the touch control signal line electrically connected to RX2 can have a length L2, the touch control signal line electrically connected to RX3 can have a length L3, ... and the touch control signal line electrically connected to RXn can have a length Ln, where L1 > L2 > L3 ... > Ln. A ratio between the length of the touch control signal line electrically connected to RX1, the length of the touch control signal line electrically connected to RX2, the length of the touch control signal line electrically connected to RX3, ... and the length of the touch control signal line electrically connected to RXn can be L1:L2:L3 ...:Ln.
[0061] Meanwhile, the ratio between the conductor width of the touch control signal line electrically connected to RX1, the conductor width of the touch control signal line electrically connected to RX2, the conductor width of the touch control signal line electrically connected to RX3,... and the conductor width of the touch control signal line electrically connected to RXn can be L1:L2:L3...:Ln. This means that each touch control signal line can have the same length-to-width ratio. Consequently, each touch control signal line can have the same resistance, and accordingly, each touch detection point on the touch control display panel 200 can still have the same touch control sensitivity.
[0062] By varying the length and / or the conductor width of the touch control measurement signal line, R1 and R2 in the touch control display panel 200 can be configured to satisfy a relationship -20% ≤ (R1 - R2) / R2 ≤ 20%, where R1 is the total resistance of the first touch control measurement electrode and the first touch control measurement signal line electrically connected to the first touch control measurement electrode, and R2 is the total resistance of the second touch control measurement electrode and the second touch control measurement signal line electrically connected to the first touch control measurement electrode. Consequently, the difference in the signal delay times of the touch control measurement signals sent by the corresponding touch control measurement electrodes 203 can be significantly reduced. Any embodiment in which R1 and R2 satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20% falls within the scope of this disclosure.
[0063] Provided that each touch control measurement signal line has a different length, in the disclosed embodiments each touch control measurement signal line can be configured to have a different line width such that the resistance of each touch control measurement signal line is substantially the same. Thus, R1 and R2 can satisfy the relationship -20% ≤ (R1 - R2) / R2 ≤ 20%, where R1 is the total resistance of the first touch control measurement electrode and the first touch control measurement signal line electrically connected to the first touch control measurement electrode, and R2 is the total resistance of the second touch control measurement electrode and the second touch control measurement signal line electrically connected to the second touch control measurement electrode.
[0064] The touch control measuring electrode 203 and the touch control actuation electrode 201 function like two plates of the capacitor formed between the touch control measuring electrode 203 and the touch control actuation electrode 201, the first touch control measuring electrode and the first touch control measuring signal line electrically connected to the first touch control measuring electrode, as shown in Fig. 7 shown.
[0065] As in Fig. As shown in Figure 7, R1 is the total resistance of the first touch control measuring electrode RX1 and the first touch control measuring signal line electrically connected to the first touch control measuring electrode RX1, and R2 is the total resistance of the second touch control measuring electrode RX2 and the second touch control measuring signal line electrically connected to the second touch control measuring electrode RX2. C1 is the capacitance of the first touch control measuring electrode RX1, and C2 is the capacitance of the second touch control measuring electrode RX2.
[0066] Referring to Fig. 2 and Fig. 7, any touch control measurement signal line 204, as in Fig. As discussed in section 2, it can be configured to have different conductor widths if each touch control measurement signal line 204 has a different length. Thus, each touch control measurement signal line 204 can have the same length-to-conductor-width ratio, which in turn can lead to the same resistance. Since each touch control measurement electrode 203 can have the same area, the associated capacitor can have the same plate area. Thus, R1*C1 can be essentially equal to R2*C2. Likewise, each touch detection point on the touch control display panel 200 can have the same value of R*C.
[0067] Specifically, the value of R*C can be reduced if the conductor width of the touch control measuring signal line 204 increases. A substantially small value of R*C can be highly desirable to reduce power consumption and improve the performance of the touch control display panel 200. However, the conductor width of the touch control measuring signal line 204, which is electrically connected to the touch control measuring electrode 203, may be limited by the edge of the touch control display panel 200. This means that, due to the limited edge of the touch control display panel 200, it may be difficult to further reduce the value of R*C.
[0068] To solve the aforementioned problem, it shows Fig. Figure 3A shows a top view of another exemplary touch control display panel according to the disclosed embodiments, in which each touch control measurement signal line can have the same line width. On the one hand, each touch detection point on the touch control display panel can still have the same touch control sensitivity. On the other hand, the touch control measurement signal line can have a continuously narrow width, so that the touch control display panel can have a continuously narrow border, saving valuable space when the touch control display panel is implemented in certain compact devices.
[0069] The similarities between Fig. 1A and Fig. Section 3A will not be repeated here, although certain differences may be explained. As in Fig. As shown in Figure 3A, the touch control indicator panel 300 can include multiple touch control actuator electrodes 301, multiple touch control measuring electrodes 303, multiple touch control measuring signal lines 304, and a first integrated circuit 305. The touch control measuring electrodes 303 can include multiple first touch control measuring electrodes and multiple second touch control measuring electrodes. The distance between the first touch control measuring electrode and the first integrated circuit 305 can be greater than the distance between the second touch control measuring electrode and the first integrated circuit 305. Each touch control measuring electrode 303 can have a different orthogonal projection surface in the plane formed by the intersecting first direction D1 and second direction D2.
[0070] In one embodiment, as in Fig. As shown in Figure 3A, the area of the touch control measuring electrode 303 can gradually decrease, or the length of each touch control measuring electrode 303 can gradually decrease in the first direction D1, as the distance from the touch control measuring electrode 303 to the first integrated circuit 305 in the first direction D1 gradually decreases. Thus, the resistance of each touch control measuring electrode 303 arranged in the first direction D1 can gradually increase. This means that in the touch control display field 300, the first touch control measuring electrode can have a lower resistance than the second touch control measuring electrode.
[0071] On the other hand, the length of the touch control measuring signal line 304, which is electrically connected to the associated touch control measuring electrode 303, can gradually decrease in the first direction D1 if the distance from the touch control measuring electrode 303 to the first integrated circuit 305 also gradually decreases in the first direction D1. Provided that the line width of each touch control measuring signal line 304 is the same, the resistance of each touch control measuring signal line 304 arranged in the first direction D1 can gradually decrease. This means that the first touch control measuring signal line can have a higher resistance than the second touch control measuring signal line.
[0072] Therefore, if the resistance difference between the first touch control measuring electrode and the second touch control measuring electrode is equal to the resistance difference between the second touch control measuring signal line and the first touch control measuring signal line, then R1 can be equal to R2, where R1 is the total resistance of the first touch control measuring electrode and the electrically connected touch control measuring signal line, and R2 is the total resistance of the second touch control measuring signal line and the electrically connected touch control measuring signal line.
[0073] This means that if Rfirst touch control measuring electrode - Rsecond touch control measuring electrode = Rsecond touch control measuring signal line - Rfirst touch control measuring signal line, then R1 can be equal to R2. Consequently, the touch detection points on the touch control display field 300 can exhibit a substantially uniform touch control sensitivity.
[0074] By varying the area of the touch control measuring electrode or the length of the touch control measuring electrode in the direction D1, R1 and R2 can be configured in the touch control display field 300 to satisfy the condition -20%≤(R1-R2) / R2≤20%, where R1 is the total resistance of the first touch control measuring electrode and the electrically connected first touch control measuring signal line, and R2 is the total resistance of the second touch control measuring electrode and the electrically connected second touch control measuring signal line.
[0075] Thus, the difference in the signal delay times of the touch control measurement signals sent by the touch control measuring electrodes 303 can be significantly reduced, and the uniformity of the touch sensitivity across the entire touch control display field 300 can be significantly improved. Any embodiment in which R1 and R2 satisfy the condition -20%≤(R1-R2) / R2≤20% falls within the scope of this disclosure.
[0076] Fig. Figure 3B shows a top view of another exemplary touch control display panel according to the disclosed embodiments. The similarities between Fig. 3A and Fig. Section 3B will not be repeated here, while certain differences may be explained below.
[0077] As in Fig. As shown in Figure 3B, the touch control display panel 300 can comprise n touch control measuring electrodes 303, for example, a touch control measuring electrode RX1, a touch control measuring electrode RXa, and a touch control measuring electrode RXb, etc., where a, b, and n can each be positive integers. Specifically, the n touch control measuring electrodes 303 can be divided into several touch control measuring electrode groups, and the touch control measuring electrodes 303 in the same touch control measuring electrode group can have the same area and the same resistance if the distance between each touch control measuring electrode 303 and the first integrated circuit 305 decreases gradually.
[0078] If the distance between each touch control electrode group and the first integrated circuit 305 gradually increases, the area of each touch control electrode in the touch control electrode groups can gradually increase, while the resistance of each touch control electrode in the touch control electrode groups gradually decreases. This means that the touch control electrodes located furthest from the first integrated circuit 305 in the touch control electrode group may have a larger area but lower resistance than the touch control electrodes located close to the first integrated circuit 305 in the touch control electrode group.
[0079] Thus, the total resistance of each touch control measuring electrode 303 and the electrically connected touch control measuring signal line 304 can be equal within the permissible error range. Accordingly, R1 and R2 can be configured to satisfy the relationship -20% ≤ (R1 - R2) / R2 ≤ 20%, where R1 is the total resistance of the first touch control measuring electrode and the electrically connected first touch control measuring signal line, and R2 is a total resistance of the second touch control measuring electrode and the electrically connected second touch control measuring signal line. The corresponding structure can be found in Fig. 3B will be explained.
[0080] As in Fig. As shown in Figure 3B, in one embodiment the touch control measuring electrode RX1 can form a first touch control measuring electrode group up to the touch control measuring electrode RXa, the touch control measuring electrode RXa+1 can form a second touch control measuring electrode group up to the touch control measuring electrode RXb, and the touch control measuring electrode RXb+1 can form a third touch control measuring electrode group up to the touch control measuring electrode RXn.
[0081] The area of each touch control measuring electrode can be determined by its length and width. Specifically, the width of the touch control measuring electrodes in the first group (i.e., RX1 to RXa) can be d1 = ... = da, the width of the touch control measuring electrodes in the second group (i.e., RXa+1 to RXb) can be da + 1 = ... = db, and the width of the touch control measuring electrodes in the third group (i.e., RXb+1 to RXn) can be db + 1 = ... = dn, where d1 = ... = da > da + 1 = ... = db > db + 1 = ... = dn.
[0082] This means that from the third touch control measuring electrode group to the first touch control measuring electrode group, the distance between the touch control measuring electrode group and the first integrated circuit 305 can gradually increase, the area of the touch control measuring electrodes in the touch control measuring electrode groups can gradually increase, while the resistance of the touch control measuring electrodes in the touch control measuring electrode groups gradually decreases.
[0083] This means that the touch control measuring electrodes in the third touch control measuring electrode group (i.e., RXb+1 to RXn) can have a smaller area and a higher resistance than the touch control measuring electrodes in the second third touch control measuring electrode group (i.e., RXa+1 to RXb). Similarly, the touch control measuring electrodes in the second third touch control measuring electrode group (i.e., RXa+1 to RXb) can have a smaller area and a higher resistance than the touch control measuring electrodes in the first third touch control measuring electrode group (i.e., RX1 to RXa). Thus, the total resistance of each touch control measuring electrode 303 and the electrically connected touch control measuring signal line 304 can be equal within the permissible error range. Accordingly, R1 and R2 can be configured to satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20%.
[0084] Provided that the resistance of each touch control measuring signal line 304 is the same, R1 and R2 in the touch control display panel 300 can be configured to satisfy the condition -20%≤(R1-R2) / R2≤20%, where R1 is a total resistance of the first touch control measuring electrode and the first touch control measuring signal line electrically connected to the first touch control measuring electrode, and R2 is a total resistance of the second touch control measuring electrode and the second touch control measuring signal line electrically connected to the second touch control measuring electrode, by varying the area of the touch control measuring electrode 303 or the length of the touch control measuring electrode 303 in the direction D1.
[0085] As with the one in Fig. 1A, Fig. 1B and Fig. In certain embodiments of the touch control display panel shown in Figure 2, the first touch control measurement signal line and the second touch control measurement signal line can be configured to have the same resistance by controlling the length and / or width of the touch control measurement signal line. Thus, resistance R1 and resistance R2 can be configured to satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20%.
[0086] As with the one in Fig. 3A and Fig. In the touch control display field shown in Figure 3B, the first touch control measuring electrode and the second touch control measuring electrode can, in certain other embodiments, be configured to have different resistances by controlling the area of the touch control measuring electrode or the length of the touch control measuring electrode in the first direction D1. Thus, the resistance R1 and the resistance R2 can be configured to satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20%.
[0087] In certain other embodiments, resistors R1 and R2 can be configured to satisfy the condition -20% ≤ (R1 - R2) / R2 ≤ 20% by controlling the length and / or width of the touch control measurement signal line, while simultaneously controlling the area of the touch control measurement electrode or the length of the touch control measurement electrode in the first direction D1. In the disclosed embodiments, the uniformity of the touch control sensitivity across the entire touch control display area can be improved.
[0088] Furthermore, in the disclosed embodiments, the touch control measuring electrode can have a shape as shown in Fig. 1A, Fig. 1B, Fig. 2 and Fig. 3A, where the distance between two adjacent touch control measuring electrodes can be a straight line. In certain embodiments, the touch control measuring electrode can have a shape other than a straight line. Certain examples are given in Fig. 4A and Fig. 4B shown.
[0089] Fig. Figure 4A shows a top view of exemplary touch control measuring electrodes according to the disclosed embodiments; as shown in Fig. As shown in Figure 4A, the distance between two adjacent touch control measuring electrodes can be a kinked line.

It should be noted that the color foil substrate 507 can have a surface facing the array substrate 506 (e.g., an inside) and a surface facing away from the array substrate 506 (e.g., an outside). The touch control sensing electrodes 503 can be arranged on the side of the color foil substrate 507 facing away from the array substrate 506, i.e., the outside of the color foil substrate 507.
[0092] The first integrated circuit 505 can receive touch measurement signals detected by the touch control measuring electrodes 503, and these touch measurement signals can be used to determine the touch position where a touch occurs.

In a display phase, each touch control driving electrode 501 can be multiplexed as a common electrode, and the first integrated circuit 505 can provide a common voltage signal to the touch control driving electrode 501 via the touch control driving signal lines 502.The common voltage signal can work with the pixel voltage signal provided for the Touch Control Display Panel 500, so that the Touch Control Display Panel can display 500 images.
[0093] During the touch phase, the first integrated circuit 505 can provide a touch control signal for the touch control control electrode 501 via the corresponding touch control control signal line 502. The touch control signal enables the touch control measuring electrodes 503 and touch control control control electrodes 501 to form multiple touch detection points, so that the touch control display panel 500 can implement the touch control.
[0094] Furthermore, the touch control display panel 500 can also include a second integrated circuit 508, the corresponding structure of which is shown in Fig. 5B is shown.

[0095] Furthermore, in the display phase, each touch control actuator electrode 501 can be multiplexed as a common electrode, and the second integrated circuit 508 can provide a common voltage signal for each touch control actuator electrode 501 via the corresponding touch control actuator signal line 502, so that the touch control display panel 500 can display images. In the touch phase, the second integrated circuit 508 can provide the touch control signal for the touch control actuator electrode 501 via the corresponding touch control actuator signal line 502, so that the touch control display panel 500 can implement the touch control.
[0096] If the touch control display panel 500 comprises both the first integrated circuit 505 and the second integrated circuit 508, in one embodiment the first integrated circuit 505 can be arranged on a first flexible printed circuit board (FPC) 509, which can be connected to the colored film substrate 507. Thus, the first integrated circuit 505 can be connected to the second integrated circuit 508 via the first flexible printed circuit board (FPC) 509.
[0097] In another embodiment, the first integrated circuit 505 can be arranged on a second flexible printed circuit board (FPC) 510.
