Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Referring to the conventional lighting control system shown in fig. 1a, the input video signal may be RGB video (i.e., RGB video), the display panel may be a lamp panel of an LED lamp, and when displaying a picture, for the low gray pixels in the picture, the on time of the LED lamp of the display panel may account for a large part of the whole lighting time due to the RC loading delay, as shown in fig. 1b, the lighting time is set to 1 clock cycle (GCLK), for the driving current provided by the Driver IC, the target current is I1, the actual current is I2, it can be seen that, the waveform difference between the actual current I2 and the target current I1 is large, the ratio of the time T1 required by the actual current to reach the target current in one clock cycle T is large, and the uncertainty of RC loading delay is added, when there are many low-gray pixels in one frame, the display of the frame usually becomes very uneven.
Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be set forth in the following embodiments.
Please refer to fig. 2, which is a schematic flowchart of a display control method according to an embodiment of the present application, where the display control method includes the following steps:
201. a controller of the display device acquires a target picture to be displayed.
The target picture can be any frame of image in a video stream to be displayed.
The lighting control system provided by the present application can be as shown in fig. 3 a. Compared with the conventional lighting control system shown in fig. 1a, the lighting control system provided by the present application directly establishes the electrical connection between the controller and the driving chip, and the driving chip and the display panel are electrically connected.
202. And if the target picture meets the preset low-gray condition, the controller adjusts display control parameters corresponding to the target picture, wherein the display control parameters comprise current gain and light-emitting time.
The preset low gray condition may refer to that a frame of picture includes more low gray pixels, the low gray pixels may refer to pixels with a gray level less than or equal to a gray level threshold (e.g., a gray level of 3), and when the preset low gray condition is satisfied, the frame of picture may be regarded as a low gray picture.
It should be noted that the above-mentioned gray level threshold value of 3 is merely illustrative and can be flexibly set as needed.
The display control parameters may specifically include current gain and light-emitting time, the magnitude of the driving current may be determined according to the current gain, and the driving chip drives the display panel to display the picture according to the corresponding driving current and light-emitting time.
Specifically, default display control parameters can be set, the default display control parameters can meet normal display requirements of non-low-gray pixels, when a controller of the display device determines that a target picture meets a preset low-gray condition, the phenomenon of uneven display can occur when the target picture is displayed directly according to the default display control parameters, and the controller can adjust the display control parameters corresponding to the target picture to obtain the adjusted display control parameters.
203. And the controller controls the driving chip to drive the display panel to display the target picture according to the adjusted display control parameters.
Specifically, the controller controls the driving chip to drive each pixel in the display target picture of the display panel according to the adjusted display control parameter, the actual driving current changes as shown in fig. 3b, taking the case that the light emitting time in the display control parameter is adjusted from 1 GCLK to 5 GCLK as an example, when the driving chip drives and displays the target picture according to the adjusted display control parameter, the time T1 required by the actual current I2 to reach the target current I1 occupies a small proportion of the whole light emitting time T, that is, the on time of the LED lamp of the display panel only occupies a small part of the whole light emitting time, so as to effectively compensate for the low-gray pixels, and improve the display non-uniformity caused by more low-gray pixels in the picture.
In some possible embodiments, if the target picture does not satisfy the preset low-gray condition, the controller may control the driving chip to drive the display panel to display the target picture according to the default display control parameter, and if the target picture is not the low-gray picture, the normal display of the target picture may be ensured by driving according to the default display control parameter.
In the embodiment of the application, a controller of a display device can acquire a target picture to be displayed, if the target picture meets a preset low-gray condition, the controller adjusts a display control parameter corresponding to the target picture, and controls a driving chip of the display device to drive a display panel of the display device to display the target picture according to the adjusted display control parameter, wherein the display control parameter comprises current gain and light-emitting time, so that the display unevenness caused by more low-gray pixels in the picture can be effectively improved by adjusting the display control parameter for compensation, and the display effect of the picture is improved.
Please refer to fig. 4, which is a schematic flowchart of another display control method provided in an embodiment of the present application, where the display control method includes the following steps:
401. a controller of the display device acquires a target picture to be displayed.
The specific implementation of step 401 may participate in the related description of step 201 in the foregoing embodiment, and is not described herein again.
In some possible embodiments, the controller may analyze the gray scale of the pixel in the target picture, and specifically may include: the controller acquires the gray scale of each pixel in the target picture, wherein the gray scale can be a numerical value between 0 and 255, acquires the number of pixels of which the gray scale is less than or equal to a gray scale threshold (for example, gray scale 3) in the target picture and the total number of pixels included in the target picture, determines the ratio between the number of pixels of which the gray scale is less than or equal to the gray scale threshold and the total number of pixels, and if the ratio is greater than or equal to the ratio threshold (for example, 70%), the controller can determine that the target picture meets a preset low gray scale condition and can treat the target picture as a low gray picture. As shown in fig. 3c, as for the result of the gray level analysis of the pixels in the target picture by the controller, taking the gray level threshold value as 3 as an example, where the pixel with the gray level of 1 accounts for 40%, the pixel with the gray level of 2 accounts for 20%, and the pixel with the gray level of 3 accounts for 10%, then the ratio of the number of pixels with the gray level less than or equal to the gray level threshold value 3 in the target picture to the total number of pixels is 70%, and when the ratio threshold value is reached, the controller may determine that the target picture meets the preset low gray condition.
402. If the target picture meets the preset low-gray condition, the controller adjusts the current gain corresponding to the target picture from a first gain to a second gain, and adjusts the light-emitting time corresponding to the target picture from a first time length to a second time length.
The second gain is smaller than the first gain, the second duration is longer than the first duration, and the first gain and the first duration are default display control parameters.
Specifically, the current gain included in the default display control parameter may be set to be a first gain, and the light-emitting time may be set to be a first duration, and if the target frame satisfies the preset low gray condition, the controller may adjust the current gain and the light-emitting time included in the default display control parameter, specifically, decrease the current gain and increase the light-emitting time, for example, decrease the current gain corresponding to the target frame from the first gain to a second gain, and increase the light-emitting time corresponding to the target frame from the first duration to a second duration.
For example, assuming that the default display control parameter has a first gain of 5, a first duration of 1 GCLK and a corresponding driving current of 2mA, the second gain may be 1, and a second duration of 5 GCLK and a corresponding driving current of 0.4 mA.
It should be noted that the values of the first gain, the first duration, the second gain, and the second duration in the above examples are merely illustrative, and can be flexibly set according to the actual product model and the requirement.
In some possible embodiments, the driving chip is exemplified by MY9748, and the driving current Iout(13/rext). times.GAIN, where rext is an external hanging powerThe resistance value GAIN is the current GAIN, when the target picture is regarded as a low-gray picture (namely, the preset low-gray condition is met), the GAIN is adjusted to be small, so that the driving current is reduced, the light-emitting time is correspondingly prolonged, and the aim of compensating the picture with uneven low gray is fulfilled.
403. And the controller takes the second gain and the second time length as adjusted display control parameters.
Specifically, the controller may use the obtained second gain and the second duration as the adjusted display control parameters, that is, the control parameters that need to be used when the target frame is driven and displayed.
404. And the controller sends the adjusted display control parameters to a driving chip, so that the driving chip drives a display panel to display the target picture according to the adjusted display control parameters.
Specifically, direct electric connection is established between the controller and the driving chip, and for a target picture meeting a preset low-gray condition, the controller can directly transmit display control parameters (namely adjusted display control parameters) adapted to the target picture to the driving chip, so that the driving chip can drive the display panel to display the target picture according to the adjusted display control parameters, and uniform display of the target picture is guaranteed.
In some feasible embodiments, the driver chip may record a default display control parameter and an adjusted display control parameter, the controller only needs to send a notification signal to the driver chip when the target picture meets a preset low-gray condition, and the driver chip drives the display panel to display the target picture according to the adjusted display control parameter after receiving the notification signal. And if the target picture does not meet the preset low-gray condition, the controller does not need to send a notification signal to the driving chip, and the driving chip does not receive the notification signal, and the display panel is driven to display the target picture according to the default display control parameters.
In some possible embodiments, for a target picture satisfying a preset low gray condition, the controller may divide pixels in the target picture into two parts, one part is a first pixel (i.e., a low gray pixel) with a gray level less than or equal to a gray level threshold value in the target picture, and the other part is a second pixel in the target picture except for the first pixel, and for the first pixel, the controller controls the driving chip to drive the display panel to display the first pixel according to the adjusted display control parameter; for the second pixel, the controller controls the driving chip to drive the display panel to display the second pixel according to the default display control parameter, so that the fineness of the display control can be improved, and the display effect of the picture can be further improved only by adjusting the display control parameter of the low-gray pixel in the low-gray picture.
In some possible embodiments, for the target picture satisfying the preset low gray condition, the second gain and the second time period to be adjusted may be determined according to the ratio, that is, the second gain and the second time period may be varied instead of a fixed value. For example, if the ratio of the number of pixels with a gray scale less than or equal to the gray scale threshold to the total number of pixels is 70% to 80%, the second gain may be 2.5, the second time duration is 2 GCLK, and the corresponding driving current is 1 mA; if the ratio is between 80% and 90%, the second gain may be 1.25, the second duration is 4 GCLK, and the corresponding driving current is 0.5 mA; the ratio is between 90% and 100%, then the second gain may be 1, the second duration is 5 GCLK, the corresponding drive current is 0.4mA, and so on.
In the embodiment of the application, the controller of the display device can acquire the target picture to be displayed, and if the target picture meets the preset low-gray condition, the controller adjusts the current gain corresponding to the target frame from the first gain to the second gain, and adjusts the light-emitting time corresponding to the target frame from the first time length to the second time length, and uses the second gain and the second time length as the adjusted display control parameters, and sending the adjusted display control parameters to the driving chip to drive the display panel to display the target picture according to the adjusted display control parameters, thereby compensating the low gray picture by synchronously adjusting the current gain and the light emitting time in the display control parameters, prolonging the light emitting time of the low gray pixel, reducing the driving current, the display unevenness caused by more low-gray pixels in the picture can be effectively improved, and the display effect of the picture is improved.
