Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As mentioned in the background art, the conventional display panel is prone to display unevenness, and the inventors have found through research that the reason why such a problem occurs is that: with the increasing requirements of users on the screen ratio of the display panel, the design of the display area opening becomes the mainstream development trend of the display panel. However, the width of the display area adjacent to the open area in the conventional display panel is smaller than the width of the other display areas, so that the load of the initialization signal line in the display area (the display area adjacent to the open area) is smaller than the load of the initialization signal line in the other display areas, and the magnitude of the initialization signal output by the initialization signal line in the display area to each sub-pixel unit is different from that in the other display areas, so that the display brightness of the display area is different from that of the other display areas, and the display of the display panel is uneven.
In view of the above problem, the present embodiment provides a display panel, and fig. 1 is a schematic diagram of a display panel according to an embodiment of the present invention, and referring to fig. 1, the display panel includes:
the display panel comprises an opening area 10 and a first display area 20 positioned on one side of the opening area 10 along a first direction X, and further comprises a first signal transmission line 30 positioned on one side of the first display area 20 far away from the opening area 10 along the first direction X, wherein the first signal transmission line 30 extends along a second direction Y; wherein the first direction X and the second direction Y cross each other.
The first display area 20 includes a plurality of sub-pixel units 21 and a plurality of first initialization signal lines 22 extending in the first direction X; a first end of each first initialization signal line 22 is electrically connected to the first signal transmission line 30, and each first initialization signal line 22 is electrically connected to a row of sub-pixel units 21 arranged in sequence along the first direction X; every adjacent n first initialization signal lines 22 are electrically connected through a first connection line 23; n is a positive integer greater than or equal to 2.
The opening area 10 does not display an image, the first display area 20 includes a plurality of sub-pixel units 21, each sub-pixel unit 21 includes a light-emitting structure and a pixel driving circuit, and the pixel driving circuit is used for driving the light-emitting structure to emit light, so as to realize image display. The first initialization signal line 22 is electrically connected to the sub-pixel unit 21, i.e., the first initialization signal line 22 is electrically connected to an initialization signal terminal of a pixel driving circuit in the sub-pixel unit 21. The first signal transmission line 30 is used to transmit an initialization signal to the first initialization signal line 22, and the first signal transmission line 30 may be located in a non-display region of the display panel. The first initialization signal line 22 is used to input an initialization signal to the pixel driving circuit, thereby initializing the pixel driving circuit. Each adjacent n first initialization signal lines 22 are electrically connected by a first connection line 23, that is, each adjacent n first initialization signal lines 22 are connected in parallel.
Specifically, since the first display region 20 is arranged side by side with the opening region 10 along the first direction X, the width of the first display region 20 along the first direction X is smaller than that of the normal display region (the display region not arranged side by side with the opening region 10) along the first direction X, the number of sub-pixel units 21 connected to each first initialization signal line 22 is smaller than that of the sub-pixel units 21 connected to the initialization signal lines of the normal display region, so that the first initializing signal line 22 is differently loaded from the initializing signal line of the normal display area, the magnitude of the initialization signal output from the first initialization signal line 22 to each sub-pixel unit 21 is different from that of the normal display area, resulting in the sub-pixel unit 21 of the first display area being initialized to a different degree from that of the normal display area, thereby causing the luminance of the sub-pixel unit 21 in the first display region to be different from the luminance of the sub-pixel unit 21 in the normal display region when the same driving signal is input during display.
Fig. 2 is an equivalent schematic diagram of a load of a first initialization signal line according to an embodiment of the present invention, referring to fig. 1 and fig. 2, since the sub-pixel units 21 are gated on a row-by-row basis during displaying, only one first initialization signal line 22 inputs an initialization signal to one row of sub-pixel units 21 at a time, when n adjacent first initialization signal lines 22 are electrically connected through the first connection line 23, the n electrically connected first initialization signal lines 22 may be equivalent to n-1 first initialization signal lines 22 corresponding to the non-conductive n-1 row of sub-pixel units 21 (hereinafter referred to as non-conductive n-1 first initialization signal lines 22) connected in parallel and then connected in series with the first initialization signal lines 22 corresponding to the conductive row of sub-pixel units 21 (hereinafter referred to as conductive first initialization signal lines 22). As shown in fig. 2, let RX be the equivalent impedance of the conducting first initialization signal line 22, and R be the equivalent impedance of each first initialization signal line 22 in the non-conducting n-1 first initialization signal lines 22. When a row of sub-pixel units 21 is initialized, the total load of the first initialization signal line 22 is RX + R/(n-1), and the load of the first initialization signal line 22 in the first display area 20 is increased, so that the initialization signal when each row of sub-pixel units 21 is initialized is close to the normal display area, the brightness of the first display area 20 is close to the normal display area, and the display uniformity of the display panel is improved.
It should be noted that n may be determined according to the width difference between the first display area 20 and the normal display area along the first direction X, and exemplary n may be 2, 3, 4, etc., as long as the initialization signal when initializing each row of sub-pixel units 21 of the first display area 20 is close to the normal display area.
Fig. 3 is a schematic diagram of another display panel according to an embodiment of the present invention. Alternatively, referring to fig. 1, the second ends of every adjacent n first initialization signal lines 22 are electrically connected by a first connection line 23. Alternatively, referring to fig. 3, every adjacent n first initialization signal lines 22 are electrically connected by a first connection line 23 at a first set position, wherein the first set position is an arbitrary position between the first and second ends of the first initialization signal lines 22.
Specifically, the positions of the first connecting lines 23 are different, the equivalent impedance of each first initializing signal line 22 connected in parallel or in series to the circuit is different, and the equivalent load of n first initializing signal lines 22 can be adjusted by adjusting the positions of the first connecting lines 23, so that the load on the first initializing signal line 22 when the first display area 20 initializes each row of sub-pixel units 21 is the same as or similar to the load on the initializing signal line in the normal display area, the initializing degree of the sub-pixel units 21 in the first display area 20 is the same as or similar to the initializing degree of the sub-pixel units in the normal display area, and the display uniformity of the display panel is improved.
Fig. 4 is a schematic diagram of another display panel according to an embodiment of the present invention. Optionally, referring to fig. 4, the display panel further includes:
a second display region 40 located on a side of the opening region 10 away from the first display region 20 along the first direction X, and a second signal transmission line 50 located on a side of the second display region 40 away from the opening region 10 along the first direction X, the second signal transmission line 50 extending along the second direction Y.
The second display area 40 includes a plurality of sub-pixel units 21 and a plurality of second initialization signal lines 41 extending in the first direction X; a first end of each second initialization signal line 41 is electrically connected to the second signal transmission line 50, and each second initialization signal line 41 is electrically connected to a row of sub-pixel units 21 sequentially arranged along the first direction X; the first initialization signal line 22 and the second initialization signal line 41 are independent of each other.
The first display area 20 and the second display area 40 are respectively located at two sides of the opening area 10, the second signal transmission line 50 is used for transmitting the initialization signal to the second initialization signal line 41, and the second signal transmission line 50 may be located in a non-display area of the display panel. The second initialization signal line 41 is used to input an initialization signal to the sub-pixel unit 21 of the second display area 40, and to initialize the sub-pixel unit 21 of the second display area 40.
By arranging the first initialization signal line 22 and the second initialization signal line 41 to be independent from each other, that is, the first initialization signal line 22 is not connected with the second initialization signal line 41, the first initialization signal line 22 can be manufactured in the first display area 20, the second initialization signal line 41 can be manufactured in the second display area 40, and the first initialization signal line 22 and the second initialization signal line 41 do not need to be connected by bypassing the opening area 10, so that the process difficulty is reduced.
Optionally, the width of the first display area 20 along the first direction X is greater than the width of the second display area 40 along the first direction X, the size of the second display area 40 is smaller, and human eyes are insensitive to the brightness of the display area with the smaller size, so that the second display area 40 has a smaller influence on the display uniformity of the display panel, and the first initialization signal line 22 and the second initialization signal line 41 are arranged to be independent from each other, so that the display panel is ensured to have better display uniformity while the difficulty of the manufacturing process of the display panel is reduced.
Fig. 5 is a schematic diagram of another display panel according to an embodiment of the present invention. Alternatively, referring to fig. 5, every adjacent m second initialization signal lines 41 are electrically connected by a second connection line 42, where m is a positive integer greater than or equal to 2.
Specifically, when m adjacent second initialization signal lines 41 are electrically connected by the second connection line 42, the m electrically connected second initialization signal lines 41 may be connected in parallel with the m-1 second initialization signal lines 41 corresponding to the m-1 non-conductive sub-pixel units 21 (hereinafter referred to as non-conductive m-1 second initialization signal lines 41) and then connected in series with the second initialization signal lines 41 corresponding to the m-1 conductive sub-pixel units 21 (hereinafter referred to as conductive second initialization signal lines 41). Let the equivalent impedance of the conducting second initialization signal line 41 be RY, and the equivalent impedance of each second initialization signal line 41 in the m-1 non-conducting second initialization signal lines 41 be r. When a row of sub-pixel units 21 is initialized, the total load of the second initialization signal line 41 is RY + r/(m-1), and the load of the second initialization signal line 41 in the second display area 40 is increased, so that the initialization signal when each row of sub-pixel units 21 in the second display area 40 is initialized is close to the normal display area, the brightness of the second display area 40 is close to the normal display area, and the display uniformity of the display panel is further improved.
Alternatively, the second ends of every adjacent m second initialization signal lines 41 are electrically connected by a second connection line 42. Alternatively, the second set positions of every adjacent m second initialization signal lines 41 are electrically connected by the second connection line 42, wherein the second set position is an arbitrary position between the first end and the second end of the second initialization signal line.
Specifically, the positions of the second connection lines 42 are different, the equivalent impedance of each second initialization signal line 41 connected in parallel or in series to the circuit is different, and the equivalent load of m second initialization signal lines 41 can be adjusted by adjusting the positions of the second connection lines 42, so that the load of the second initialization signal line 41 when the second display area 40 initializes each row of sub-pixel units 21 is the same as or similar to the load on the initialization signal line in the normal display area, the initialization degree of the sub-pixel units 21 in the second display area 40 is the same as or similar to the initialization degree of the sub-pixel units in the normal display area, and the display uniformity of the display panel is improved.
Fig. 5 only shows the case where the second end of the second initialization signal line 41 is electrically connected through the second connection line 42, and the case where the second setting position of the second initialization signal line 41 is electrically connected through the second connection line 42 is not shown, which is not a limitation of the present invention.
Optionally, with continued reference to fig. 5, the display panel further includes:

Specifically, referring to fig. 5, the third display area 60 has a width a in the first direction X, and the first display area 20 has a width B in the first direction X. When the load on the third initialization signal line 61 is RA after the sub-pixel units 21 in one row in the third display area 60 are turned on during initialization, the display effect of the display panel is best when RA is RX + R/(n-1), and at this time n-1 is (RA-RX)/R. RA is related to the length of the third initialization signal line 61, RX is related to the length of the first initialization signal line 22, and RA-RX may be equivalent to K (a-B), where K is a set coefficient. Therefore, a specific value of n may be selected according to a difference in length between the third display area 60 and the first display area 20, and a specific value of m may be selected according to a difference in length between the third display area 60 and the second display area 40, in the same manner, so as to minimize a difference in luminance between the first display area 20 and the second display area 40 and the third display area 60.

Specifically, the film position of the first connection line 23 may be determined according to the wiring requirement of the display panel, and when the first connection line 23 does not affect other structures of the film where the first initialization signal line 22 is located, the first connection line 23 and the first initialization signal line 22 may be arranged on the same layer, so that the first connection line 23 and the first initialization signal line 22 may be prepared in the same process, and structures such as a through hole are not required to be arranged so that the first connection line 23 and the first initialization signal line 22 are electrically connected, thereby reducing the process difficulty. When the first connecting line 23 affects other structures of the film layer where the first initializing signal line 22 is located, the first connecting line 23 and the first initializing signal line 22 may be arranged in different layers to ensure that other structures of the display panel work normally.
