These terms are only used to distinguish the display area, the scan line, and the touch unit from each other. For example, the first display area, the scan line, and the touch unit may also be referred to as a second display area, a scan line, and a touch unit, and similarly, the second display area, the scan line, and the touch unit may also be referred to as a first display area, a scan line, and a touch unit, without departing from the scope of the embodiments of the present invention.
An embodiment of the present invention provides a display panel 100, as shown in fig. 1, the display panel 100 includes a display area 10 and a non-display area 20. The display area 10 has at least one notch 30, and the notch 30 is connected to the edge of the display area 10, i.e. the display area 10 is not a regular rectangle, but a figure with the notch 30. The notch 30 is located in the non-display area 20, that is, the notch 30 has no display function and cannot display normally. The notch 30 may be completely cut out of the display panel, or may be a transparent region. The display area 10 further includes a first display area 11 and a second display area 12, and the first display area 11 and the second display area 12 are arranged in the first direction Y.
Referring to fig. 1 and 2, the display panel 100 includes a plurality of first scan lines G1, a plurality of second scan lines G2, a plurality of Data lines Data, and a plurality of first touch units T1 and a plurality of second touch units T2. The first scan lines G1 are located in the first display region 11, and the first scan lines G1 extend along the second direction M and are arranged along the first direction Y. The second scan lines G2 are located in the second display region 12, and the second scan lines G2 extend along the second direction M and are arranged along the first direction Y. The length of the first scanning line is less than that of the second scanning line. That is, since the notch 30 is aligned with the first display region 11 in the second direction M, the extension of the first scan line G1 is cut off, that is, the width of the first display region 11 in which the first scan line G1 is located in the second direction M is smaller than the width of the second display region 12 in which the second scan line G2 is located in the second direction M.
With continued reference to fig. 1 and fig. 2, the first touch unit T1 overlaps the first display area 11, and the length of a complete first touch unit T1 in the first direction Y is a first length B, where B >0. The second touch unit T2 is located in the second display area 12, and a length of the complete second touch unit T2 in the first direction is a second length D, D >0. Note that, a complete first touch unit T1 and a complete second touch unit T2 refer to the first touch unit T1 and the second touch unit T2 which are not adjacent to the notch portion 30 and are not "cut" by the notch portion 30. The first touch unit T1 and the second touch unit T2 are a complete unit capable of determining a touch position, and should at least include a touch electrode.
With continued reference to fig. 1 and 2, the length of the notch 30 along the first direction N is a third length Y, Y >0. The first length B, the second length D and the third length Y satisfy the relation: y is less than or equal to 1.3D and D is less than or equal to B is less than or equal to 1.3D.
In the display panel 100 of the embodiment of the invention, the third length Y of the notch 30 along the first direction N does not exceed 30% of the second length D of the second touch unit T2 along the first direction N in the normal display area, and the first length B of the first touch unit along the first direction N is not 30% of the second length D of the second touch unit along the first direction N in the normal display area. So that the first touch units T1 can be reasonably arranged according to the length of the notch portion 30 in the first direction N. Therefore, the problem of touch failure is avoided, the design of the first touch units T1 on the two sides of the notch portion 30 is simplified, and the problem of visible graphs on the two sides of the notch portion 30 is solved.
Alternatively, as shown in fig. 1, the display panel 100 includes two first display regions 11, and the notch portion 30 is located between the two first display regions 11. That is, the cut-out portion 30 has a "sea shape" or a "hat brim shape" or a "water drop shape", as long as the first display regions 11 are provided on both sides of the cut-out portion 30.
Alternatively, in the embodiment of the present invention, the notch 30 may also be located at one corner of the display area 10, i.e. in a chamfered shape. As shown in fig. 3, the display panel 100 includes a first display region 11, and the notch portion 30 and the first display region 11 are arranged in the second direction M. The first display area 11 may be located on the right side of the notch 30.
As shown in fig. 4, the first length B of the first touch unit T1 and the second length D of the second touch unit T2 may be set to be equal, so that the touch uniformity of the entire display panel 100 is stronger. When the first touch unit T1 and the second touch unit T2 have the same size and shape, the processing complexity of the touch chip is lower, the transmission, reading and analysis of the touch signal are uniform, and the entire display panel 100 has a particularly excellent touch effect. At this time, in order to ensure the touch effectiveness, the depth of the cut of the notch portion 30, that is, the third length Y, needs to be set not more than 30% of the first length B of the first touch unit T1, that is, the first length B of the first touch unit T1 and the third length Y of the notch portion 30 satisfy the relationship: 0<Y ≦ 1.3B. At this time, if a part of the second touch units T2 is "cut", not less than 70% of the length of the second touch units T2 in the first direction N may remain, and the touch function may be effectively maintained. At this time, only one row of the first touch units T1 is disposed on both sides of the notch 30, which effectively simplifies the design of the first display areas 11 on both sides of the notch 30. The touch function of the first display area 11 can be mainly used for operations such as a slide-down menu, and the display of the first display area 11 mainly includes information such as power information, signal information, and date and time, and the required touch precision and frequency are not high.
The display panel 100 according to the embodiment of the invention not only solves the problem of touch uniformity, but also reasonably plans the number of the first touch units T1 and the length along the first direction N according to the arrangement of the first display areas 11 on both sides of the notch portion 30, simplifies the touch design and solves the problem of touch failure. In addition, the first touch unit T1 can be wired from both sides without using the notch portion 30 for winding and has a size similar to that of the second touch unit T2, thereby solving the problem that the peripheral pattern of the notch portion 30 is visible.
In the display panel 100 of the embodiment of the invention, as shown in fig. 2, a third length Y of the notch 30 along the first direction N is equal to a first length B of the first touch unit T1 along the first direction N. That is, the length of the first display region 11 in the first direction N is maintained to be equal to the third length Y of the notch portion 30 in the first direction N. The first touch unit T1 is only located in the first display area 11, and the design of the second touch unit T2 in the second display area 12 is not affected. At this time, in consideration of the touch uniformity and the complexity design of the signal processing of the touch chip, the second length D of the second touch unit T2 of the display panel 100 along the first direction N does not exceed 30% of the first length B of the first touch unit T1 along the first direction N, that is, the first length B of the first touch unit T1 along the first direction N and the second length D of the second touch unit T2 along the first direction N satisfy the relationship: d < B ≦ 1.3D.
In the display panel 100 provided in the embodiment of the present invention, while the first length B of the first touch unit T1 and the third length Y of the notch 30 are maintained, the second length D of the second touch unit T2 is set within a specific range, and the problems of touch failure and touch uniformity are solved at the same time, in addition, the first touch unit T1 can be routed from two sides without using the notch 30 for winding, and the size of the first touch unit T1 is similar to that of the second touch unit T2, so that the problem that the peripheral graph of the notch 30 is visible is solved.
The second touch unit T2 of the display panel 100 provided by the embodiment of the invention only needs to have a function of detecting a touch position, and the second touch unit T2 may adopt various design schemes. As shown in fig. 5A, the second touch unit T2 includes a second transmitting electrode 41, a second receiving electrode 42 and a second bridge 43. The second transmitting electrode 41 is located at the same layer as the second receiving electrode 42. The extending direction Z of the second overpass 43 intersects the first direction N, and the extending direction Z of the second overpass 43 intersects the second direction M.
When the second touch units T2 are arranged by using the design of fig. 5A, a touch array as shown in fig. 5B may be formed. The second transmitting electrodes 41 located in the same row are connected together, and the second receiving electrodes 42 located in the same column are electrically connected through a second bridge 43. The extending direction of the second bridge 43 forms a certain angle with the extending direction of the gate line and the extending direction of the data line, that is, the extending direction Z of the second bridge 43 is not parallel to the first direction N and the extending direction Z of the second bridge 43 is not parallel to the second direction M, so that the problem of visible touch can be further reduced.
It should be noted that the second transmitting electrode 41 and the second receiving electrode 42 of the second touch unit T2 may be interchanged with each other as a receiving electrode and a transmitting electrode. A second touch virtual electrode 44 may be disposed between the second transmitting electrode 41 and the second receiving electrode 42 of the second touch unit T2 to improve the touch effect. As shown in fig. 6A, the second touch unit T2 includes a second transmitting electrode 41, a second receiving electrode 42, a second bridge 43 and a second touch virtual electrode 44. The second transmitting electrode 41 is located at the same layer as the second receiving electrode 42. The extending direction Z of the second overpass 43 intersects the first direction N, and the extending direction Z of the second overpass 43 intersects the second direction M.
When the second touch units T2 are arranged using the design of fig. 6A, a touch array as shown in fig. 6B may be formed. The second transmitting electrodes 41 located in the same row are connected together, and the second receiving electrodes 42 located in the same column are electrically connected through a second bridge 43. The extending direction of the second bridge 43 forms a certain angle with the extending direction of the gate line and the extending direction of the data line, that is, the extending direction Z of the second bridge 43 is not parallel to the first direction N and the extending direction Z of the second bridge 43 is not parallel to the second direction M, so that the problem of visible touch can be further reduced. The second touch virtual electrode 44 is located between the adjacent second receiving electrode 42 and the second transmitting electrode 41.
Optionally, as shown in fig. 7, the first touch unit T1 includes a first transmitting electrode 51, a first receiving electrode 52 and a first bridge 53. The first transmitting electrode 51 is located at the same layer as the first receiving electrode 52. That is, the second touch unit T2 may adopt a mutual capacitance touch driving and detecting manner. The extending direction Z of the first bridge 53 intersects the first direction N, and the extending direction Z of the first bridge 53 intersects the second direction M.
It should be noted that fig. 7 only shows one structure of the first touch unit T1, and in other embodiments of the present invention, the first touch unit T1 may also include other structures. As shown in fig. 8, the first touch unit T1 includes a first transmitting electrode 51, a first receiving electrode 52, a first bridge 53 and a first dummy electrode 54. The first transmitting electrode 51 is located at the same layer as the first receiving electrode 52. That is, the second touch unit T2 may adopt a mutual capacitance touch driving and detecting manner. The extending direction Z of the first bridge 53 intersects the first direction N, and the extending direction Z of the first bridge 53 intersects the second direction M.
Optionally, as shown in fig. 9, each first touch unit T1 includes a first touch electrode 61 and a first touch lead 62, and the first touch electrode 61 is electrically connected to the first touch lead 62 located in the same touch unit and is insulated from the first touch leads 62 located in other touch units. That is, the first touch unit T1 and the second touch unit T2 may adopt different designs and touch driving manners. For example, the second touch unit T2 may adopt a mutual capacitance touch driving and detecting method, and the first touch unit T1 may adopt a self-capacitance touch driving and detecting method. When the self-capacitance touch driving and detecting method is adopted for the first display area 11, each first touch unit T1 has stronger independence and is not affected by the position of the notch 30.
As shown in fig. 10, a width of a complete first touch unit T1 in the second direction M is a first width a, a width of a cut first touch unit T1 in the second direction M is a second width X, and the first width a and the second width X satisfy a relationship: 0 instead of (1) is less than or equal to 0.7A ≦ X. In order to ensure the touch effectiveness at both sides of the notch portion 30, at least 70% of the width of the first touch unit T1 adjacent to the notch portion 30 is reserved in the second direction M. That is, the cutting depth of the notch 30 in the second direction M is less than 30% of the width of a complete first touch unit T1 in the second direction M.
In the display panel 100 according to the embodiment of the present invention, the size of the touch electrode adjacent to the notch portion is set in the transverse cutting depth and the longitudinal cutting depth of the notch portion 30, so that the touch effectiveness around the notch portion 30 is ensured. By setting the size relationship between the first touch unit T1 and the second touch unit T2, the problem of visible patterns caused by non-uniformity of the touch units around the notch 30 is solved.
