Description

Display panel, driving method thereof and electronic equipment

Technical Field

The present disclosure relates to the field of display technologies, and in particular, to a display panel, a driving method thereof, and an electronic device.

Background

At present, a data driving chip in a display outputs a pixel voltage to a pixel unit through a data line. Because the number of data lines in the display is large, correspondingly, the data driving chip needs more pins. In order to reduce the number of data driving chips, a multiplexer MUX is disposed between the data driving chips and the data lines in the related art, and referring to fig. 1, the data driving chips may be connected to three pixel sub-units RGB through the MUX (may be referred to as a 1:3MUX scheme). For example, as shown in fig. 1(a), channels S1, S2, S3, and S4 connect the three pixel sub-cells RGB of the pixel cells P1, P2, P3, and P4, respectively; as shown in fig. 1(B), channels S1 and S2 are mixed to connect pixel units P1 and P2, where S1 is connected to R (P1), B (P1) and G (P2), respectively, S2 is connected to G (P1), R (P2) and B (P2) (shown by dashed lines in fig. 1, for the difference from S1), and channels S3 and S4 are similar. The data driving chip may also be connected to six pixel sub-units through a MUX (which may be referred to as a 1:6MUX scheme). For example, as shown in fig. 1(c), the channel S1 connects the three pixel sub-units RGB in the pixel units P1 and P2, respectively.

In the process of implementing the embodiment of the present disclosure, the inventors found that:

the related art 1:3MUX scheme (the scheme shown in fig. 1 (a)) and the 2:6MUX scheme (the scheme shown in fig. 1 (b)) require more pins of the data driving chip. In a scene that the display requires high-resolution display, the size of the data driving chip is large, which causes the size of the lower frame of the display to be increased, and is not beneficial to the design of the wide frame. Moreover, when the pin data of the data driving chip is more, the yield is reduced in the bonding process.

The related art 1:6MUX scheme (the scheme shown in fig. 1 (c)) requires an increase in the driving capability of the data driving chip, for example, the increased driving capability is about twice as large as the driving capability of the 1:3MUX scheme. On the one hand, the design of the data driving chip is complex and is not beneficial to realization.

In comprehensive comparison, the 1:3MUX scheme needs to provide enough charging time for the display process, and the display process time is increased within a fixed frame time, so that the touch time is squeezed, the touch time is insufficient, and the touch performance of the display cannot be guaranteed.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

Fig. 2 is a schematic diagram illustrating a connection relationship between a data driving chip and a pixel unit in a display panel according to an exemplary embodiment. Referring to fig. 2, the display panel includes a data driving chip DI, a plurality of multiplexers MUXn (denoted by reference numerals MUX1, MUX2, and MUX3 in fig. 2 as different MUXs) and columns of pixel units Pn (denoted by reference numerals P1, P2, P3, P4 in fig. 2 as different pixel units, including three pixel sub-units RGB for each pixel unit); the data driving chip DI is electrically connected to the MUXs through data transmission lines Sn (denoted by reference numerals S1, S2, S3 in fig. 2 as different data transmission lines), and the MUXs are electrically connected to the columns of pixel cells P through data lines Dn (denoted by reference numerals D1, D2, D3 … … in fig. 2 as different data lines);

the ratio of the number of data transmission lines Sn to the number of data lines Dn is 3: 12; and two adjacent data lines Dn receive pixel voltages transmitted by different data transmission lines.

In this way, when image frame data required to be displayed in the next frame is acquired, the data driving chip DI controls the MUXn to switch, that is, a pixel voltage output channel is formed among the data driving chip DI, the data transmission lines Sn, MUXn, the data line Dn and the pixel unit Pn, and then the data driving chip DI outputs a pixel voltage to the data line of the corresponding column through the data transmission line, so that the pixel voltage is output to the corresponding pixel unit.

As can be seen, the ratio of the number of data transmission lines Sn to the number of data lines Dn in this embodiment is 3: 12, namely the ratio of the number of input ends to the number of output ends of each MUX is 1: 4, the loading capacity of the MUX can be improved, so that under the condition that the number of the data lines is not changed, the number of the data transmission lines is reduced, the size of the data driving chip can be reduced, and the size of a frame of the display is favorably reduced. In addition, in the embodiment, the charging time and the driving capability in the display process can be taken into consideration, the time in the display process can not be increased, and the driving capability of the data driving chip is not required to be increased, so that the touch time of the display can not be influenced, and the touch performance of the display can be favorably ensured.

Fig. 3 is a schematic diagram illustrating connection relationships of MUXs according to an exemplary embodiment, and referring to fig. 3, each MUX in the MUXn includes an input terminal and 4 output terminals, or a ratio of the number of input terminals to the number of output terminals is 1: 4. for the adjacent three MUXs, the adjacent three output terminals of the data driving chip DI are respectively connected to the input terminals of the first MUX (MUX 1 in fig. 2), the second MUX (MUX 2 in fig. 2) and the third MUX (MUX 3 in fig. 2). For one of the three adjacent MUXs, the 4 output ends of the first MUX, the second MUX and the third MUX are respectively and electrically connected with four adjacent pixel units in the multi-column pixel units.

In an embodiment of the present disclosure, the electrically connecting the respective 4 output terminals of the first MUX, the second MUX and the third MUX with the adjacent four pixel units in the columns of pixel units includes: the 4 output ends of the first MUX are respectively and electrically connected with the first pixel sub-unit of each pixel unit in the four adjacent pixel units; the 4 output ends of the second MUX are respectively and electrically connected with the second pixel sub-unit of each pixel unit in the four adjacent pixel units; the 4 output ends of the third MUX are electrically connected to the third pixel sub-unit of each of the four adjacent pixel units, respectively.

Referring to fig. 2, an input terminal of a first MUX, i.e., MUX1, is connected to the data line S1, and 4 output terminals of the MUX1 are connected to the data line D1, the data line D4, the data line D7, and the data line D10, in this order. The input terminal of the second MUX, MUX2, is connected to the data line S2, and the 4 output terminals of the MUX2 are connected to the data line D2, the data line D5, the data line D8, and the data line D11 in this order. The input terminal of the third MUX, MUX3, is connected to the data line S3, and 4 output terminals of the MUX3 are connected to the data line D3, the data line D6, the data line D9, and the data line D12 in this order. That is, the MUX1 is electrically connected to the red pixel sub-units R1 to R4 in the pixel cells P1 to P4, the MUX2 is electrically connected to the green pixel sub-units G1 to G4 in the pixel cells P1 to P4, and the MUX3 is electrically connected to the blue pixel sub-units B1 to B4 in the pixel cells P1 to P4.

When the data driving chip acquires the image frame data required to be displayed in the next frame, the data driving chip determines the number of colors corresponding to the image frame data, and the number of the colors can be one, two or three.

When the number of colors is one, for example, the color is red, the data driver chip DI controls the MUX1 to switch to output 1, output 2, output 3, and output 4 in turn. Since the image frame data to be displayed includes only red, the data driving chip DI does not need to drive the MUX2 and the MUX3, and only needs to control the MUX 1. Thus, the time for the data driving chip DI to control the MUX1 to output the pixel voltage to the pixel sub-unit in the same column can be extended to 3 times, so that the data driving chip DI has enough time to sequentially output the pixel voltage to the red pixel sub-unit R1, the red pixel sub-unit R2, the red pixel sub-unit R3 and the red pixel sub-unit R4 through the data transmission line S1 and the data lines D1, D4, D7 and D10.

When the number of colors is two, for example, the colors are red and green, the data driving chip DI controls the MUX1 to sequentially switch to output terminal 1, output terminal 2, output terminal 3, and output terminal 4 to be connected to the data lines D1, D4, D7, and D10, respectively, and controls the MUX2 to sequentially switch to output terminal 1, output terminal 2, output terminal 3, and output terminal 4 to be connected to the data lines D2, D5, D8, and D11, respectively. Since the image frame data to be displayed only contains red and green, the data driving chip DI does not need to drive MUX3, and only needs to control MUX1 and MUX2, so that the time for the data driving chip DI to control MUX1 or MUX2 to output the pixel voltage to the same column of pixel sub-units can be extended to 1.5 times the original time, so that the data driving chip DI has enough time to sequentially output the pixel voltage to red pixel sub-unit R1, red pixel sub-unit R2, red pixel sub-unit R3 and red pixel sub-unit R4 through data transmission line S1 and data lines D1, D4, D7 and D10, and the data driving chip DI has enough time to sequentially output the pixel voltage to green pixel sub-unit G1, green pixel sub-unit G2, green pixel sub-unit G3 and green pixel sub-unit G4 through data transmission line S2 and data lines D2, D5, D8 and D11.

When the number of the colors is three, the data driving chip DI sequentially drives the MUX1, the MUX2, and the MUX3 to output the pixel voltages to the pixel sub-units in the corresponding column.

It can be understood that, according to the relationship between the display time and the touch time, fig. 4 is a schematic diagram of the display time and the touch time according to an exemplary embodiment, referring to fig. 4, within the time of fixing one frame of image, the sum of the display time and the touch time is fixed, that is, the charging time of the display time is reduced, and the time reserved for the touch operation is increased.

It can be seen that, in the embodiment, by adjusting the connection relationship between the data transmission line Sn and the data line Dn, when the image frame data to be displayed only includes one or two colors, the time for the data driving chip DI to output the pixel voltage to the pixel sub-units in the corresponding column is prolonged, and the prolonged time is less than or equal to the time saved by reducing the number of colors of the image frame to one or two colors, so that the pixel voltage can be reliably output without increasing the driving capability of the data driving chip DI. In addition, the display time is unchanged or reduced for a fixed image frame, namely the touch time is unchanged or increased, so that the touch performance of the display can be ensured.

In practical applications, the data driving chip DI may drive the pixel units Pn in the display panel in a column inversion or dot inversion manner. The polarities of two adjacent pixel sub-units in the adjacent 4 pixel units Pn are opposite. For the control manner of column inversion or dot inversion, reference may be made to related technologies, and details are not described herein.

In a column inversion or dot inversion driving manner, in this embodiment, the electrically connecting the respective 4 output ends of the first MUX, the second MUX and the third MUX with the adjacent four pixel units in the multiple columns of pixel units includes:

the 4 output ends of the third MUX are respectively and electrically connected with the second pixel sub-unit of the second pixel unit, the first pixel sub-unit of the third pixel unit, the first pixel sub-unit of the fourth pixel unit and the third pixel sub-unit.

Based on the above control manner of column inversion or dot inversion, the present embodiment provides another connection relationship between the data driving chip and the pixel unit, and fig. 5 is a schematic diagram illustrating the connection relationship between the data driving chip and the pixel unit in a display panel according to another exemplary embodiment. Referring to fig. 5, three adjacent output terminals of the data driving chip DI are connected to a first MUX1, a second MUX2, and a third MUX3 through data transmission lines S1, S2, and S3, respectively.

4 output terminals of the MUX1 (the structure of the MUX can refer to FIG. 2) are connected to the red pixel sub-unit R1(+), the blue pixel sub-unit B1(+), the blue pixel sub-unit B2(-) of the pixel unit P1, and the green pixel sub-unit G3(-) of the pixel unit P3 through the data lines D1, D3, D6, and D8, respectively.

The 4 output terminals of the MUX2 are connected to the green pixel sub-unit G1(-) of the pixel cell P1, the red pixel sub-unit R2(-) of the pixel cell P2, the blue pixel sub-unit B3(+) of the pixel cell P3, and the green pixel sub-unit G4(+) of the pixel cell P4 through the data lines D2, D4, D9, and D11, respectively.

The 4 output terminals of the MUX3 are connected to the green pixel sub-unit G2(+), the red pixel sub-unit R3(+), the red pixel sub-unit R4(-) of the pixel unit P3, and the blue pixel sub-unit B4(-) of the pixel unit P4 of the pixel unit P2 through the data lines D5, D7, D10, and D12, respectively.

The data driving chip DI acquires image frame data required to be displayed in the next frame, determines the polarity of the pixel voltage of each pixel subunit under the current image frame data according to the image frame data, and then controls the MUX to switch according to the polarity, so that the data driving chip DI outputs the pixel voltage to the corresponding pixel subunit through the data transmission lines Sn, MUXn and the data line Dn.

For example, the data driving chip DI outputs pixel voltages to the red pixel sub-unit R1(+), the blue pixel sub-unit B1(+), the blue pixel sub-unit B2(-) and the green pixel sub-unit G3(-) through the MUX1 and the data lines D1, D3, D6 and D8. The data driving chip DI outputs pixel voltages with positive polarity to the corresponding data lines D1 and D3, then the data driving chip DI switches to negative polarity, and outputs pixel voltages with negative polarity to the data lines D6 and D8, so that the positive and negative polarities of the data driving chip DI only need to be switched twice, and compared with 4 times of positive and negative polarity switching required by the pixel sub-units adjacent to the pixel sub-units connected with the MUXn, the two times of positive and negative polarity switching can be reduced, and thus the power consumption is saved.

With reference to fig. 5, in the present embodiment, under the condition of reducing the positive and negative polarity switching frequency, the time for the data driving chip DI to output the pixel voltage to the pixel unit is reduced, and for a fixed image frame, the reduction of the display time can increase the touch time, so as to ensure the touch performance of the display. Alternatively, the data driving chip DI may extend the time for outputting the pixel voltage, the extended time is less than or equal to the time saved by reducing the positive and negative polarity switching frequency, and the pixel voltage can be reliably output without increasing the driving capability of the data driving chip DI. Moreover, the display time is unchanged or reduced for a fixed image frame, namely the touch time is unchanged or increased, so that the touch performance of the display can be ensured.
