Detailed Description
Currently, among the existing display panels having the abnormal region, a display panel having the abnormal region located at the top of the display region is taken as an example.
It should be noted that, the special-shaped area is located on the display panel and is located on the same plane as the display area, and is different from the display area, and the special-shaped area may be a non-display area for setting other devices, such as a camera, a receiver, a microphone, a sensor, etc.; the profiled region may also comprise a display area of a small number of pixel cells for displaying a low resolution image, for example for displaying information such as time, date, temperature, icons etc.
As shown in fig. 2, the data lines 01 in the display area B1 at both sides of the abnormal area are connected from top to bottom along the column direction, in the display area B2 containing the abnormal area a, since the substrate of the display panel in the abnormal area a is cut away and the data lines cannot be arranged in the abnormal area, the data lines 02 in the display area B2 are connected from the bottom of the abnormal area a to the bottom of the whole display panel along the column direction, the data lines arranged in the display area B1 and the display area B2 are compared, and since the abnormal area a is contained in the display area B2, the length of the data lines 02 in the display area B2 is shorter than the length of the data lines 01 in the display area B1, and in the signal loading process, the loading of the two areas is different, so that the display effect is finally different.
Aiming at the problem that the data line loading is different due to the abnormal area in the prior art, the embodiment of the invention provides a display panel and a display device. In order to make the technical solution and advantages of the present invention more clear, the following describes in detail the specific embodiments of the display panel and the display device provided by the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the following description of the preferred embodiments is provided for the purpose of illustrating and explaining the invention, and is not intended to limit the invention. And embodiments and features of embodiments in this application may be combined with each other without conflict.
The shapes and sizes of the various components in the drawings do not reflect true proportions and are intended to illustrate the invention only.
Specifically, as shown in fig. 3, an embodiment of the present invention provides a display panel, where a display area of the display panel includes a plurality of columns of pixels 01;
the display area is divided into a first display area B1 and a second display area B2, and the number of pixels of one column of pixels 01 in the second display area B2 is smaller than that of pixels of one column of pixels 01 in the first display area B1;
the first display area B1 is provided with a first data line 02 connected to each column of pixels 01, the second display area B2 is provided with a second data line 03 connected to each column of pixels 01, and in the column direction, the length of the first data line 02 is longer than the length of the second data line 03;
the display panel further includes third data lines 04 in one-to-one correspondence with and electrically connected to the second data lines 03.
The length of the second data line 03 is smaller than that of the first data line 02, so that in view of the fact that third data lines 04 which are in one-to-one correspondence with the second data lines 03 exist in the display panel, the existence of the third data lines 04 can make up for the length difference between the second data lines 03 and the first data lines 02, and in signal transmission, the loading difference of signals between the first data lines 02 and the second data lines 03 is reduced, so that the display difference between the first display area B1 and the second display area B2 caused by the loading difference is avoided.
It should be noted that, in the embodiment of the present invention, the pixel 01 may be a pixel including an organic light emitting diode, or may be a pixel including a liquid crystal.
Optionally, as shown in fig. 4a, the display panel further includes a special-shaped area a, where in fig. 4a, the special-shaped area a is located above the second display area B2 along the column direction, and in practical application, the special-shaped area a may be provided with one of a camera, a receiver, a light sensor, a distance sensor, an iris recognition sensor, and a fingerprint recognition sensor, or may be a combination of the above devices, for example, the receiver and the camera may be provided at the same time, or the camera, the distance sensor, and the light sensor may be provided at the same time; the mounting device on the abnormal region A improves the effective utilization rate of the abnormal region A on the display panel and simultaneously increases the functionality of the display panel.
The above devices are all exemplified, and all devices that can be disposed in the profiled region a are applicable to the embodiments of the present invention.
It should be noted that, in the embodiment of the present invention, when the special-shaped area a is used for setting a device, the substrate needs to be kept in the special-shaped area a, but no thin film is evaporated on the substrate, so as to ensure that the special-shaped area a is a transparent area.
Specifically, the illustrated abnormal region a may be located at the top end of the second display region B2 along the column direction, as shown in fig. 4a and 4B, in fig. 4B, two first display regions B1 and one second display region B2 are included, and the abnormal region a is located between the two first display regions B1 and is located at the top end of the second display region B2 along the column direction; the special-shaped area a may also be located at the bottom end of the second display area B2 along the column direction, as shown in fig. 4c, the special-shaped area a includes a first display area B1, a second display area B2, and the special-shaped area a is located at one side of the first display area B1 and at the bottom end of the second display area B2 along the column direction; the special-shaped area a may also be located between the second display areas B2, as shown in fig. 4d, two first display areas B1 and two second display areas B2 are included, the two first display areas B1 and the special-shaped area a are disposed at intervals, and the special-shaped area a is located between the two second display areas B2; the arrangement positions of the special-shaped areas A are various, the position distribution of each area in the display panel is more flexible, and different positions of the special-shaped areas A can meet different application requirements in actual scenes.
Preferably, when the data lines are arranged, a third data line 04 is arranged in the abnormal area A; when the special-shaped area a is located at the top end of the second display area B2 along the column direction, as shown in fig. 4B, in fig. 4a and fig. 4B, a third data line 04 is arranged in the special-shaped area a located at the top end of the second display area B2 along the column direction, the data lines arranged in the second display area B2 are second data lines 03, and the second data lines 03 and the third data lines 04 are in one-to-one correspondence and keep an electrical connection state; when the special-shaped area a is located at the bottom end of the second display area B2 along the column direction, the connection manner of the data lines on the display panel is as shown in fig. 4c, the third data lines 04 arranged in the special-shaped area a are in one-to-one correspondence with the second data lines 03 arranged in the second display area B2, and the electrical connection state is maintained.
Specifically, when the second data line 03 and the third data line 04 are located in different layers in the display panel, in order to ensure that the two data lines are electrically connected, the second data line 03 and the third data line 04 may be electrically connected through a via structure, as shown in fig. 5a, which is a longitudinal sectional view of the display panel shown in fig. 4a, which is obtained by cutting the second display area B2 along the data line longitudinally, where the two data lines are located in different layers, an insulating layer 05 is present between the second data line 03 and the third data line 04, the third data line 04 is close to the substrate 06 of the display panel, a via structure 07 is formed on the insulating layer 05, and the second data line 03 is electrically connected with the third data line 04 through the via structure 07. The two data lines are ensured to be electrically connected in a via hole mode, so that the two data lines are conducted, and the data transmission difference between the second data line 03 and the first data line 02 is reduced.
It should be noted that, in a plurality of cases where two data lines are located in different layers, for example, as shown in fig. 5B, which is a cross-sectional view of a display panel that is a liquid crystal display panel, the drain 08 of the thin film transistor in the second display area B2 is electrically connected to the pixel electrode 09 through a via hole, the gate electrode 11 is used to connect to a signal line in the display panel, no pixel exists in the area 12 where the third data line 04 is located, the second data line 03 is connected to the source 10 of the thin film transistor in the second display area B2, the second data line 03 is in the same layer as the source 10 and the drain 08 of the thin film transistor, and the third data line 04 is disposed on the substrate 06 of the display panel, so that the two data lines are located in different layers, and the second data line 03 and the third data line 04 can be electrically connected through the via hole structure 07; the above cases where the two data lines are located in different layers are only examples, and all cases where the two data lines are located in different layers are applicable to the embodiments of the present invention.
Preferably, in order to reduce the manufacturing difficulty, the second data line 03 and the third data line 04 may be disposed on the same film layer in the display panel, as shown in fig. 5c, which is a longitudinal sectional view of the display panel shown in fig. 4a, which is obtained by cutting the second display area B2 along the data line, where the two data lines are disposed on the same film layer, and the second data line 03 and the third data line 04 are disposed in a manner that the second data line 03 and the third data line 04 are disposed on the same film layer without an insulating layer 05 therebetween, so that a via structure may not be disposed, and the second data line 03 and the third data line 04 may be directly electrically connected in the film layer. The two data lines are arranged on the same film layer, so that the complexity of the manufacturing process is reduced, and the conduction of the two data lines is ensured.
As shown in fig. 5d, for example, in the cross-sectional view of the display panel that is a liquid crystal display panel, the drain 08 of the thin film transistor in the second display area B2 is electrically connected to the pixel electrode 09 through a via hole, a small number of pixels exist in the area 12 where the third data line 04 is located, the drain 08 of the thin film transistor in the area 12 is electrically connected to the pixel electrode 09 through a via hole, the second data line 03 is connected to the source 10 of the thin film transistor in the second display area B2, the second data line 03 is in the same layer as the source 10 and the drain 08 of the thin film transistor, the third data line 04 is in the same layer as the source 10 and the drain 08 of the thin film transistor, so that the second data line 03 and the third data line 04 can be directly electrically connected to each other in the same layer.
The third data lines 04 are arranged on the special-shaped area A, the space of the special-shaped area A is fully utilized, meanwhile, the third data lines 04 have enough arrangement space, the third data lines 04 can be in one-to-one correspondence with the second data lines 03 and are in an electric connection state, and therefore loading differences between the second data lines 03 and the first data lines 02 are reduced.
Preferably, the material of the third data line 04 includes, but is not limited to, transparent ITO (Indium tin oxide), metal, and alloy, and any data line material that can be used for transmitting signals is suitable for the embodiments of the present invention; if the material of the third data line 04 arranged in the special-shaped area a is a non-transparent data line such as metal, alloy, etc., the third data line 04 should avoid devices such as a camera, a receiver, a sensor, etc. arranged on the special-shaped area a as much as possible, so as to ensure that the devices arranged on the special-shaped area a are not affected by the data line, as shown in fig. 6, the special-shaped area a does not include pixels, and the third data line 04 is arranged side by side, and the receiver 14 is arranged in the special-shaped area a, so that in order to ensure the sound receiving effect of the receiver 14 and the receiver is not affected by the data line in the working process, the third data line 04 adopts a fold line arrangement mode when passing through the receiver, so that no overlapping area exists between the third data line 04 and the receiver 14; the above-mentioned manner of avoiding the devices on the special-shaped area a is merely illustrative, and in practical applications, there are many ways of avoiding, for example, the size of the devices may be adjusted to avoid overlapping between the data lines and the devices, and the arrangement density of the third data lines 04 in the special-shaped area a may also be changed to ensure that there is enough space for arranging other devices in the special-shaped area a, and any manner that there is no overlapping between the third data lines 04 and the devices arranged on the special-shaped area a is applicable to the embodiments of the present invention.
If the material of the third data line 04 arranged on the special-shaped area a is transparent data lines such as transparent ITO, devices such as cameras, receivers and sensors arranged on the special-shaped area a can be avoided, so that the complexity and the process difficulty of the arrangement of the data lines are further reduced.
Optionally, in order to more precisely ensure the transmission synchronization of the data lines in the display area, the lengths of the first data line 02, the second data line 03 and the third data line 04 may be set, for example, the length of the third data line 04 in the column direction is equal to the difference between the length of the first data line 02 in the column direction and the length of the second data line 03 in the column direction, so that the length of the first data line 02 in the column direction is equal to the sum of the length of the second data line 03 and the length of the third data line 04, so that the total resistance of the second data line 03 and the third data line 04 is similar to the resistance of the first data line 02, and the consistency of signal loading on the second data line 03 and the first data line 02 can be better ensured during signal transmission.
Preferably, in order to reduce delay of the data line when transmitting signals, the third data line 04 and the second data line 03 may be in direct contact to form an electrical connection; when the data lines are arranged, the second data line 03 can also cross the second display area B2 and the special area a, and the data line on the special area a is the third data line 04, that is, the third data line 04 is a part of the second data line 03 in the special area a, so that the manufacturing process is reduced, and the manufacturing difficulty is reduced.
The display panel also comprises a flexible circuit board 15, wherein the flexible circuit board 15 comprises an integrated circuit (Integrted Circuit, IC) 16, the IC16 in the flexible circuit board 15 sends signals to the pixels 01 on the display area through data lines, and the pixels 01 in the display area are driven to display images in the display area; specifically, the positions of the flexible circuit board 15 can be classified into two types as follows:
