Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, specific embodiments of a display panel, a driving method thereof and a display device according to an embodiment of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 to 4 show a display panel according to an embodiment of the present invention, and fig. 1 and 3 show schematic top-view structures of the display panel according to the embodiment of the present invention, fig. 2 and 4 are schematic circuit structures corresponding to the display panels shown in fig. 1 and 3, respectively, and include a display area, the display area is divided into a first display area a1 and a second display area a2, each of the first display area a1 and the second display area a2 includes a plurality of pixel units RC distributed in an array and a plurality of scan lines G connected to the pixel units RC (only some of the pixel units RC and some of the scan lines G are illustrated in fig. 2 and 4), in the embodiment of the present invention, a load corresponding to one pixel unit is represented by one resistor R and one capacitor C, that is, one RC corresponds to one pixel unit, the plurality of scan lines G are connected to a GOA unit, and the GOA unit is configured to input a scan signal to the scan line G; the number of pixel cells RC connected per scanning line G in the first display region a1 is smaller than the number of pixel cells RC connected per scanning line G in the second display region a 2; the first display region a1 further includes a compensation unit 1 for load compensating the first display region a 1; wherein,
each scanning line G in the first display area a1 is connected to the same compensation unit 1 through a control switch T.
In the display panel provided by the embodiment of the invention, because the number of the pixel units connected with each scanning line in the first display area is less than that of the pixel units connected with each scanning line in the second display area, the load capacity of the pixel units in the first display area is less than that of the pixel units in the second display area. When the pixel driving circuit drives the first display area and the second display area, the data writing capacities of the first display area and the second display area are the same, the brightness difference cannot be generated between the first display area and the second display area, the uniformity of a display picture is improved, and the phenomenon of poor display is avoided; in addition, each scanning line arranged in the invention is respectively connected with the same compensation unit through the corresponding control switch, namely when each line of scanning lines of the first display area is scanned line by line, only one compensation unit is needed to realize load compensation on each line of pixel units by matching with the corresponding control switch, the structure is simple, the space for manufacturing the compensation unit is saved, the process difficulty is reduced, and the product yield is improved.
It should be noted that the scan line in the display panel has a certain resistance, the scan line is coupled with other film layers in the display panel to form a capacitor, and the resistance and the capacitor cause delay in signal transmission, that is, the scan line has a certain load amount, generally, the scan line and the data line intersect to define a plurality of pixel units, and each pixel unit corresponds to a load amount formed by one resistance and one capacitor, so in the embodiment of the present invention, each pixel unit is represented by one resistance and one capacitor, that is, the pixel unit is represented by an RC.
Further, in practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2 and fig. 4, the compensation unit 1 includes a plurality of first compensation circuits 11 connected in series, wherein a load amount of each first compensation circuit 11 is the same as a load amount of each pixel unit RC; the first display area a1 has a trench area 2 without pixel cells RC, and along the extending direction of the scan line G (the extending direction of the scan line G is horizontal direction in the embodiment of the present invention), the orthographic projection of the trench area 2 on the display panel substrate (not shown in fig. 2 and 4) has a side L with the smallest width, and the number of the pixel cells RC in the second display area a2 corresponding to the side L with the smallest width is the same as the number of the first compensation circuits 11; specifically, as shown in fig. 2, the trench region 2 is a rectangle, and the widths of the opposite sides L along the extending direction of the scan line G are the same, that is, the side L with the smallest width, and the number of the first compensation circuits 11 in the compensation unit 1 is the same as the number of the pixel units RC in the second display region a2 (the RC in the oval dashed-line frame in the second display region a 2) corresponding to the side L with the smallest width; as shown in fig. 4, the trench region 2 is an inverted trapezoid, the side L with the smallest orthographic projection width is the bottom side of the inverted trapezoid along the extending direction of the scanning line G, and the number of the first compensation circuits 11 in the compensation unit 1 is the same as the number of the pixel units RC in the second display region a2 (the RC in the oval dashed-line frame in the second display region a 2) corresponding to the side L with the smallest width (the bottom side of the inverted trapezoid).
Further, in practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2, the number of the pixel units RC connected to each scan line G in the first display area a1 is the same, the number of the first compensation circuits 11 in the compensation unit 1 is the first number, the number of the pixel units RC connected to one scan line G in the first display area a1 is the second number, the number of the pixel units RC connected to one scan line G in the second display area a2 is the third number, and the sum of the first number and the second number is equal to the third number. Therefore, by adding the compensation unit 1 including the plurality of first compensation circuits 11, the load amount of the pixel units RC in the first display area a1 and the load amount of the pixel units RC in the second display area a2 can be substantially the same, so that the load difference between the first display area a1 and the second display area a2 can be compensated, when the pixel driving circuit drives the first display area a1 and the second display area a2, the data writing capacities of the first display area a1 and the second display area a2 are the same, the brightness difference between the first display area a1 and the second display area a2 is not generated, the uniformity of the display screen is improved, and the phenomenon of poor display is avoided.
Further, in the display panel according to the embodiment of the invention, as shown in fig. 4, the trench region 2 has an inverted trapezoid structure, which results in that the number of the pixel units RC connected to each scan line G in the first display region a1 is different, the first display region a1 further includes second compensation circuits 21 (shown in the right-angled inverted trapezoid in fig. 4) connected to each scan line G, wherein the load capacity of each second compensation circuit 21 is the same as the load capacity of each pixel unit RC; the number of the first compensation circuits 11 in the compensation unit 1 is a first number, the number of the pixel cells RC to which one of the scanning lines G is connected in the first display region a1 is a second number, the number of the pixel cells RC to which one of the scanning lines G is connected in the second display region a2 is a third number, the number of the second compensation circuits 21 is a fourth number, and the sum of the first number, the second number, and the fourth number is equal to the third number. Therefore, by adding the compensation unit 1 including the plurality of first compensation circuits 11 and adding the second compensation circuit 21 connected to each scan line G in the first display area a1, the load amount of the pixel cell RC in the first display area a1 can be substantially the same as the load amount of the pixel cell RC in the second display area a2, so that the load difference between the first display area a1 and the second display area a2 can be compensated, and when the pixel driving circuit drives the first display area a1 and the second display area a2, the data writing capability of the first display area a1 and the data writing capability of the second display area a2 are the same, and no luminance difference occurs between the first display area a1 and the second display area a2, thereby improving the uniformity of the display screen and avoiding the occurrence of poor display.
Further, in practical implementation, in the display panel provided by the embodiment of the invention, as shown in fig. 2 and 4, the control switch T and the second compensation circuit 21 are located at the side a of the trench region 2 close to the first display region a1, and the compensation unit 1 is located at the side L of the trench region 2 close to the second display region a 2. Therefore, the frame space of the groove area 2 can be fully utilized, signal routing is easier to design, and the frame of the groove area 2 can be made narrower.
Further, compared with the traditional method that a compensation unit is correspondingly arranged on each row of grid lines in the first display area to perform load compensation on each row of pixels, the load compensation needs to be performed by software for simulation calculation, and the more complex the structure of the compensation unit, the larger the calculation amount is, and the longer the consumed time is; compared with the current mainstream load compensation mode, the embodiment of the invention adopts a more simplified compensation unit structure to realize the same function, and is simpler, more convenient and faster in the design and calculation stage.
Further, since the shape of the trench region is usually irregular, when drawing the compensation unit of the trench region, the MASK designer cannot perform a simple array like drawing the second display region, but needs to adjust the structure and position of the compensation unit according to the shape of the trench region, which is not only tedious and prone to error; the display panel provided by the embodiment of the invention can realize the load compensation of each row of pixels by only one compensation unit, thereby greatly reducing the drawing workload of designers and being not easy to make mistakes.
Further, in the display panel provided by the embodiment of the invention, when the groove area is not rectangular or trapezoidal, the groove area may have other special shapes (such as rounded corners, water drops, etc.). The design of the compensation unit described above can be extended on the basis of the embodiment shown in fig. 4. Firstly, the minimum width of the trench region 2 along the extending direction of the scan line G is found, then the number of the first compensation circuits 11 in the compensation unit is designed according to the minimum width, then the number of the second compensation circuits 21 electrically connected with the scan lines G in other rows in the first display region a1 is set, the sum of the number of the second compensation circuits 21 in each row, the number of the pixel units RC and the number of the first compensation circuits 11 is ensured to be equal to the number of the pixel units RC connected with the scan lines G in one row in the second display region a2, and the second compensation circuits 21 are connected with the first compensation circuits 11 through a control switch T.
Further, in practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2 and fig. 4, the first compensation circuit 11 includes resistors R and capacitors C, each resistor R is connected in series, one end of each capacitor C is connected between two adjacent resistors R, and the other end is grounded; one end of the resistor R close to the control switch T is connected with the first poles of all the control switches T; the grid electrode and the second pole of each control switch T are connected with the scanning line G of the corresponding row. Specifically, when displaying, the pixel cell RC of each row is electrically connected to the compensation cell through the corresponding control switch T, the gate of the control switch T is conducted with the first electrode, when the scan driving signal of the scan line of one row is active, the control switch T of the corresponding row is turned on to gate the electrically connected compensation cell 1, and at this time, the control switches T of other rows are turned off, so that the row and the other rows do not affect each other, thereby realizing the load compensation of the first display region a 1.
Further, in a specific implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 4, the second compensation circuit 21 also includes resistors R and capacitors C, each resistor R is connected in series, one end of each capacitor C is connected between two adjacent resistors R, and the other end is grounded; one end of the resistor R in each row, which is close to the control switch T, is connected to the second pole of the control switch T of the corresponding row.
It should be noted that, according to the load amount formed by the resistor and the capacitor in the first compensation circuit and the second compensation circuit provided by the embodiment of the present invention, the load amount is calculated through simulation according to the load amount corresponding to each pixel unit, and the load amounts formed by the resistor and the capacitor in the first compensation circuit and the second compensation circuit are both the same as the load amount corresponding to each pixel unit, so that one load amount is represented by the resistor R and the capacitor C in the first compensation circuit and the second compensation circuit.
Further, in practical implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2 and 4, the display panel is driven by a single side, each scan line G in the first display area a1 is disposed around the trench area 2, and only one set of the control switch T and the compensation unit 1 is included in the first display area a 1.
The driving principle of the display panel shown in fig. 1 and 2 according to the embodiment of the present invention is described by taking single-side driving as an example: if the trench area is rectangular, as shown in fig. 1, the circuit structure shown in fig. 2 can be used for compensation, fig. 2 only shows the circuit structure of the first display area a1 of the display panel, and the second display area a2 is a normal display area without load compensation; the display panel is generally designed to be left-right symmetric, so the right side is not shown. In fig. 2, since the trench area 2 is rectangular, the missing load of each row of pixel units RC in the first display area a1 is the same, so that only the load compensation unit 1 of one row of pixels needs to be designed, and the compensation unit 1 is shared by other rows of scanning lines G. A control switch T is arranged between each row of scanning lines G and the compensation unit 1 as a compensation switch. Specifically, as shown in fig. 2, when performing display, the pixel cell RC of each row is electrically connected to the compensation cell through the corresponding control switch T, the gate of the control switch T is connected to the first electrode, when the scan driving signal of one row of scan lines is active, the control switch T of the corresponding row is turned on to gate the electrically connected compensation cell 1, and the control switches T of other rows are turned off at this time, so that the row and the other rows do not affect each other, thereby realizing load compensation for the first display area a 1.
Specifically, the principle of one-sided driving of the display panel shown in fig. 3 and 4 is the same as that of one-sided driving of the display panel shown in fig. 1 and 2.
Further, in a specific implementation, in the display panel provided in the embodiment of the present invention, the display panel may be dual-side driven, each scan line in the first display region is symmetrically disconnected from the trench region, and the first display region includes two sets of symmetrically arranged control switches and compensation units. The principle of each side drive is the same as the one-side drive described above.
It should be noted that the display panel shown in fig. 2 and fig. 4 only illustrates a left-side structure schematic diagram, when the display panel is single-side driven, the right-side structure includes the pixel cell RC located at the right side of the trench region 2, the right-side structure is the same as the structure in the left-side a1, and the right-side pixel cell RC is connected around the trench region 2 by the corresponding row of the scan line G; when the display panel is driven bilaterally, the structure on the right side includes a pixel unit RC disposed on the right side of the trench region 2, and a group of control switches T and compensation units 1 disposed on the right side of the trench region 2, the control switches T and the compensation units 1 on the left and right sides of the trench region 2 are symmetrically disposed, and the scan lines G in the first display region a1 are symmetrically disconnected from each other through the trench region 2.

Of course, in the shift register provided in the embodiment of the present invention, all the control switches may also be N-type transistors.
Further, in specific implementation, the N-type transistor is turned on under the action of a high potential and is turned off under the action of a low potential; the P-type transistor is turned off under the action of a high potential and turned on under the action of a low potential.
It should be noted that the first pole of the control switch T mentioned in the above embodiments of the present invention may be a source, and the second pole is a drain, or the first pole may be a drain, and the second pole is a source, which are not specifically distinguished herein.
