The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "first," "second," and "second" are used herein for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, the display panel includes two modes, namely an unfolded state and a folded state, the display panel can be switched between the unfolded state and the folded state, when the display panel is in the unfolded state, the display surfaces of the display panel are all facing the same side, and when the display panel is in the folded state, the folded two split-screen display surfaces are all facing the outer side of the display panel and are oppositely arranged.
Referring to fig. 1, a display panel of the present application is divided into a main screen area MA and a sub screen area SA, and when the display panel is in an unfolded state, the main screen area MA and the sub screen area SA display an output picture together, and when the display panel is in a folded state, the main screen area MA displays the output picture. That is, in the unfolded state, since the main screen area MA and the sub-screen area SA are displayed to the same side, the main screen area MA and the sub-screen area SA can output images at the same time, and the output images can be two images independent of each other or a whole sub-image; in the folded state, the main screen area MA and the sub screen area SA are displayed at different sides, so that the main screen area MA is used for outputting a picture, and the output picture is a picture interacted with the display panel by a user.
In the prior art, the main screen area MA and the sub screen area SA are designed to adopt independent GIP (Gate in Panel) signals, when the display is in a folded state, the picture of the sub screen area SA is turned off, and after the display is turned off for a long time, the threshold voltage Vth of the pixel circuit TFT (Thin Film Transistor ) of the sub screen area SA is shifted, so that when the display is switched to an unfolded state, the brightness of the main screen area MA and the brightness of the sub screen area SA are inconsistent, and a split screen phenomenon is generated. In order to solve the above problems, the present application adopts the following schemes:
referring to fig. 2, the driving method of the display panel of the present application includes:
s100, when the display panel is detected to be in a folded state, controlling the display panel to be in a first working state at least within a preset time period, wherein when the display panel is in the first working state, the main screen area MA is controlled to display an output picture, and meanwhile, the auxiliary screen area SA is controlled to display a preset picture.
First, the driving method of the present application is performed by a driving chip for driving a display panel to display.
Specifically, when the display panel is detected to be in the folded state, the display panel is controlled to be in a first working state at least within a preset period of time, wherein the first working state refers to that a main screen area MA of the display panel displays an output picture, a user can directly interact with the display panel through the main screen area MA, and pixels of a sub-screen area SA are in a lighting state and are used for displaying a preset picture. The preset picture can be defined before the manufacturing end leaves the factory or can be defined by a user end when the manufacturing end leaves the factory, and the type of the preset picture can be a solid-color picture or a multicolor picture.
The preset duration may be less than or equal to the duration of the display panel in the folded state, for example, the duration of the display panel in the folded state is 2 minutes, and then the display panel may be controlled to be in the first working state within the 2 minutes, that is, within the 2 minutes, the auxiliary screen area may display the preset picture, or may be controlled to be in the first working state only within 1 minute, that is, the auxiliary screen area may display the preset picture only within 1 minute.
That is, in the scheme of this application, when display panel is in the folded condition, the vice screen district can show the picture of predetermineeing at least for a period of time, and vice screen district can not be in the state of closing all the time to compare in prior art, this application controls vice screen district SA in predetermineeing the duration at least and shows the picture of predetermineeing, can improve the threshold value drift problem that the pixel circuit of vice screen district SA appears, promotes main screen district MA and vice screen district SA luminance homogeneity, and then eliminates the phenomenon of dividing the screen.
Further, the preset screen is a black screen. When the preset picture is a black picture, the user is hard to perceive the auxiliary screen area SA, and the influence on the existing display experience is minimal.
Of course, in some other embodiments, the preset screen may be a solid screen with other colors, for example: white, red, green, blue, or the like.
Referring to fig. 3, the step of controlling the sub-screen area SA to display the preset screen in the step S100 includes:
s210: and starting the STV signal and the EIN signal corresponding to the auxiliary screen area SA.
S220: and providing gray scale voltages for the data lines in the auxiliary screen area SA so that the auxiliary screen area SA displays a preset picture.
Specifically, referring to fig. 4, the signals in the figure include a gate scan start signal STV1 of the main screen area MA, a light-emitting scan start signal EIN1 of the main screen area MA, a gate scan start signal STV2 of the sub screen area SA, a light-emitting scan start signal EIN2 of the sub screen area SA, and a data input signal Source, wherein the STV1 signal and the EIN1 signal are used together to turn on the display of the main screen area MA, the STV2 signal and the EIN2 signal are used together to turn on the display of the sub screen area SA, and the Source signal provides signal data voltages. At this time, in the embodiment of fig. 4, the STV1 signal and the EIN1 signal of the main screen area MA are in an on state, and when the scan line in the main screen area MA is scanned, the driving chip supplies the data signal to the data line in the main screen area MA, so that the main screen area MA displays the output picture, and for the sub-screen area SA, the STV2 signal and the EIN2 signal thereof are also in an on state, and when the scan line in the sub-screen area SA is scanned, the driving chip supplies the gray voltage to the data line in the sub-screen area SA, so that the sub-screen area SA outputs the black picture.
In an embodiment, the gray scale voltage may be between the first gray scale voltage and the second gray scale voltage, for example, between 6V and 8V, specifically, may be 6.5V, 7V, 7.5V, or the like.
Further, the gray scale voltages include a maximum gray scale voltage VGMP. The maximum gray level voltage VGMP can ensure the sub-screen area SA to output a better black picture.
Of course, in some other embodiments, other voltage values may be provided to the data lines in the sub-screen area SA, so that the sub-screen area SA displays other preset pictures.
Referring to fig. 1 and 5, the step S100 specifically includes:
s110: when the display panel is detected to be in the folded state, the display panel is controlled to switch between a first working state and a second working state. When the display panel is in the second working state, the main screen area MA is controlled to display the output picture, and the picture display of the auxiliary screen area SA is closed.
Specifically, the first working state is that the main screen area MA of the display panel outputs the picture, the auxiliary screen area SA displays the preset picture, the second working state is that the main screen area MA of the display panel outputs the picture, and the auxiliary screen area SA is closed for display, so that compared with the two working states, the power consumption of the second working state is obviously lower than that of the first working state.
Of course, in some other embodiments, the second working state may not be set, that is, the display panel is always in the first working state in the folded state, that is, when the display panel is in the folded state, the auxiliary screen area will always display the preset screen.
Further, when the display panel is in the folded state, the ratio of the total time length of the display panel in the second working state to the total time length of the display panel in the first working state is 0.5-15.
Specifically, for example, the ratio may be 0.5, 1, 5, 15, or the like. Specific ratio is not limited in this application, and in general, selecting a smaller ratio can reduce power consumption of the display panel, and selecting a larger ratio can improve the effect of improving split screen.
Of course, in some other embodiments, the total duration of the first operating state may be greater than or equal to the total duration of the second operating state. Or the total duration of the first working state and the total duration of the second working state can be customized by the user or matched with the using habit of the user.
In the step S110, when detecting that the display panel is in the folded state, the step of controlling the display panel to switch between the first working state and the second working state includes: when the display panel is detected to be in a folded state, the working state of the display panel is controlled to be periodically changed; in each period, the display panel is in a first working state in a first preset time period and is in a second working state in a second preset time period.
Specifically, the working state of the display panel changes periodically, and the stability is better because the periodical change is the same in each period.
Further, the first preset duration is less than or equal to the second preset duration. Under each period, the first preset time length is smaller than the second preset time length, so that the power consumption of the display panel under each period can be reduced, and the power consumption of the display panel in the whole period is further reduced.
Further, the first preset time period is longer than the second preset time period. Under each period, the first preset time length is longer than the second preset time length, so that the improvement effect of the split screen phenomenon can be improved.
Further, the ratio of the second preset time period to the first preset time period is 0.5-15. For example, the ratio of the second preset duration to the first preset duration may be 0.5, 1, 5, 15, or the like. In general, selecting a smaller ratio can reduce power consumption of the display panel, and selecting a larger ratio can improve the split screen effect. In one embodiment, the first predetermined time period is equal to 10 seconds and the second predetermined time period is equal to 50 seconds. One period in the setting is 60 seconds, wherein the first working state takes 10 seconds, the second working state takes 50 seconds, and the ratio of the duration of the second state to the duration of the first working state is 5. In another embodiment, the first preset duration is equal to 5 seconds and the second preset duration is equal to 55 seconds. One period in the setting is 60 seconds, wherein the first working state takes 5 seconds, the second working state takes 55 seconds, and the ratio of the duration of the second state to the duration of the first working state is 11. In yet another embodiment, the first preset duration is equal to 20 seconds and the second preset duration is equal to 10 seconds. One period in the setting is 30 seconds, wherein the first working state takes 20 seconds, the second working state takes 10 seconds, and the ratio of the duration of the second state to the duration of the first working state is 0.5. It is understood that the first preset duration and the second preset duration may be other, and the application is not particularly limited.
Of course, in some other embodiments, the operating state of the control display panel may also be changed aperiodically.
Referring to fig. 6, in an application scenario, the step of closing the sub-screen area SA in step S110 includes: and closing the STV signal and the EIN signal corresponding to the auxiliary screen area SA, and controlling the data line in the auxiliary screen area SA to be in a high-resistance state Hiz.
Specifically, when the STV2 signal and the EIN2 signal corresponding to the sub-screen area SA are turned off, the data line signal cannot be written into the data line in the sub-screen area SA, so that the display of the sub-screen area SA is turned off. Because the data line signals cannot be written into the data lines in the auxiliary screen area SA at this time, the data lines in the auxiliary screen area SA are directly in the high-resistance state Hiz, that is, no signals are input into the data lines in the auxiliary screen area SA, so that the power consumption of the display panel in the second working state can be further reduced.
Referring to fig. 7, in another application scenario, the step of closing the sub-screen area SA in step S110 includes: the STV signal and the EIN signal corresponding to the sub-screen area SA are turned off, and a low level signal is input to the data line in the sub-screen area SA.
Specifically, the STV2 signal and the EIN2 signal corresponding to the auxiliary screen area SA are closed, and meanwhile, the driving chip inputs a low-level signal to the data line, and the low-level signal can enable the preset picture of the auxiliary screen area SA to be immediately closed, so that the picture can be quickly closed, and the problem of residual preset picture is avoided.
The step of controlling the sub-screen area SA to display the preset screen in step S100 includes controlling the sub-screen area SA to display the preset screen unchanged.
Specifically, the preset picture is kept unchanged, the same preset picture can be output to reduce voltage variation, or the same preset picture is kept by reducing refresh frames, so that the power consumption of the display panel can be reduced.
For a better understanding of the aspects of the present application, the following description is provided in connection with the examples:
in this example, please refer to table 1, the resolution of the display panel is 2348×2048, the resolution of the main screen area MA is 2348×1048, and the resolution of the sub-screen area SA is 2348×1000, wherein Vtotal is all the scanning lines of the display panel.
When the display panel is in the unfolded state, STV1, STV2, EIN1, EIN2 and Source are all turned on, and the main screen area MA and the sub-screen area SA are both turned on to output pictures. When the display panel is in the first working state, the STV1 and the EIN1 are both started, the STV2 and the EIN2 are also started, the main screen area MA starts to output pictures, and the Source provides the maximum gray voltage VGMP, so that the pictures of the auxiliary screen area SA are black. When the display panel is in the second working state, the STV1 and the EIN1 are both opened, the STV2 and the EIN2 are closed, the main screen area MA is opened, and the auxiliary screen area SA is closed.
In the prior art, when the display panel is folded, the display panel is always in the second working state, that is, the auxiliary screen area is always in the closed state. The difference between the display panel and the prior art is that when the display panel is folded, the display panel is at least in a first working state within a preset time period, the threshold drift problem of the pixel circuit of the auxiliary screen area SA can be improved by adding the first working state, the brightness uniformity of the main screen area MA and the auxiliary screen area SA is improved, and then the split screen phenomenon is eliminated.
