[ detailed description ] of the invention
The present application is described in further detail below with reference to the drawings and examples. It is specifically noted that the following examples are only for illustration of the present application, but do not limit the scope of the present application. Likewise, the following embodiments are only some, but not all, of the embodiments of the present application, and all other embodiments obtained by one of ordinary skill in the art without inventive effort are within the scope of the present application.
Referring to fig. 1, fig. 1 is a flow chart of an image display method according to an embodiment of the present application, and the specific flow chart of the image display method may be as follows:
s11: an image signal is acquired.
In this embodiment, the above-described image display method can be applied to various display devices (e.g., transparent display devices). The display device may include a processing unit, a timing controller, a memory (e.g., an eeprom), a data driver, a scan driver, and a display panel (e.g., a liquid crystal display panel). The display panel may include a plurality of pixel units, a plurality of scan lines, and a plurality of data lines. The processing unit can be a central processing unit of a personal computer or a notebook computer and is used for outputting the image signal to the time schedule controller.
Specifically, the image signal may be acquired by the timing controller in the above-described display apparatus. The number of the image signals may be at least one frame, and one frame of the image signals may represent a combination of a plurality of image signals provided to all pixel units in the display panel within one frame of the display time.
S12: and carrying out brightness analysis on the image signal to obtain the maximum brightness value required by the display of the image signal.
Specifically, the timing controller in the display device may then perform brightness analysis on the image signal after the image signal is acquired, so as to obtain a maximum brightness value required for displaying the image signal.
In one embodiment, the maximum brightness value required for displaying the image signal may be specifically the maximum brightness value required for displaying one frame of the image signal. In order to obtain the maximum luminance value required for displaying a frame of image signal, the number of pixel units of each luminance value in the frame of image signal may be counted, for example, the vertical axis may be taken as the number of pixel units, the horizontal axis may be taken as the luminance value, the luminance histogram of the frame of image signal may be calculated, and then the maximum luminance value satisfying the number of pixel units greater than the preset number (for example, 25) may be taken as the maximum luminance value required for displaying the frame of image signal. For example, the number of pixel units having luminance values of I1, I2, and I3 is 20, 30, and 40, respectively, and I1 is smaller than I2, I2 is smaller than I3, and the preset number is 25, and the luminance values satisfying the number of pixel units greater than the preset number are I2 and I3, and the maximum luminance value satisfying the number of pixel units greater than the preset number is I3 because I2 is smaller than I3. In other embodiments, in order to obtain the maximum brightness value required for displaying a frame of image signal, the maximum value of the brightness values of all the pixel units in the frame of image signal may be used as the maximum brightness value required for displaying the frame of image signal, that is, the maximum brightness value is the brightness value of the pixel unit with the highest brightness in the frame of image signal.
In another embodiment, the number of the image signals may be multiple frames, and as shown in fig. 2, the step S12 may specifically include:
s121: the multi-frame image signals are divided into at least one image signal group, and each image signal group comprises image signals of continuous multi-frames.
Specifically, the timing controller in the display device may divide the multi-frame image signals into at least one image signal group according to a frame sequence after acquiring the multi-frame image signals. The number of frames of the video signals included in the different video signal groups may be the same, for example, each video signal group may include a video signal with a continuous preset number of frames, where the preset number of frames is greater than 1 frame, for example, may be 10 frames.
S122: and carrying out brightness analysis on all the frame image signals in each image signal group to obtain the maximum brightness value required by displaying all the frame image signals in each image signal group.
Specifically, in order to obtain the maximum brightness value required for displaying all the frame image signals in one image signal group, brightness analysis may be performed on each frame image signal in all the frame image signals in the image signal group to obtain a single frame maximum brightness value required for displaying each frame image signal in the image signal group, so as to obtain a plurality of single frame maximum brightness values, and then the maximum value in the plurality of single frame maximum brightness values may be used as the maximum brightness value required for displaying all the frame image signals in the image signal group.
S13: and determining a preset driving parameter corresponding to the maximum brightness value, wherein the preset driving parameter comprises a preset gamma voltage.
In this embodiment, the maximum brightness value may be positively correlated with the corresponding preset gamma voltage, so that when the brightness of the image to be displayed is low, the display device can be driven to display the image with a smaller gamma voltage, thereby avoiding the problem that when the brightness of the image to be displayed is low, the display device is driven to display the image with an excessive gamma voltage, so that the power consumption of the data driver of the display device is larger, and reducing the display power consumption of the display device.
In a specific embodiment, as shown in fig. 2, S13 may specifically include:
s131: and determining a preset brightness interval in which the maximum brightness value is located as a target brightness interval.
S132: and acquiring preset driving parameters corresponding to the target brightness interval.
Specifically, the luminance values of the pixel units in the image signal may be divided into different preset luminance intervals according to the magnitude or the luminance level in advance, and each preset luminance interval corresponds to a preset driving parameter. And, after analyzing and obtaining the maximum brightness value required by the display of the image signal, the timing controller in the display device may take the preset brightness interval where the maximum brightness value is located as the target brightness interval, and may obtain the preset driving parameter corresponding to the target brightness interval from the preset driving parameter lookup table.
The driving parameter lookup table may record the correspondence between a plurality of preset brightness intervals and a plurality of preset driving parameters. Also, in some embodiments, each of the preset driving parameters may include a preset Gamma (Gamma) voltage, a preset common voltage (Vcom), a preset Analog Voltage (AVDD), and the like. Correspondingly, the driving parameter lookup table may record the corresponding relation between a plurality of preset brightness intervals and a plurality of preset gamma voltages, the corresponding relation between a plurality of preset brightness intervals and a plurality of preset public voltages, and the corresponding relation between a plurality of preset brightness intervals and a plurality of preset analog voltages.
In the embodiment in which the preset driving parameters include the preset gamma voltage, the preset common voltage and the preset analog voltage, for each preset driving parameter, the absolute value of the difference between the preset gamma voltage and the preset common voltage included in the preset driving parameter is positively correlated with the corresponding maximum brightness value (or preset brightness interval), that is, the smaller the maximum brightness value (or the brightness value in the preset brightness interval), the smaller the absolute value of the difference between the preset gamma voltage and the preset common voltage included in the corresponding preset driving parameter. Further, the preset gamma voltage and the preset analog voltage included in each preset driving parameter may be positively correlated, that is, the larger the preset gamma voltage included in each preset driving parameter is, the larger the preset analog voltage included in each preset driving parameter is, so that the problem that the power consumption of the power chip of the display device is larger due to the fact that the analog voltage output by the power chip is too large when the gamma voltage required by image display is smaller can be avoided, the overall power consumption of the display device is reduced, and the display power consumption of the display device is further reduced.
S14: and driving the display equipment to display the image of the corresponding image signal according to the preset driving parameters.
Specifically, after determining the preset driving parameter corresponding to the maximum brightness value, when the image signal to which the maximum brightness value belongs needs to be displayed, the gamma voltage, the common voltage and the analog voltage output by the power chip in the display device can be respectively adjusted to the preset gamma voltage, the preset common voltage and the preset analog voltage included in the preset driving parameter corresponding to the maximum brightness value, so as to drive the display device to display the image of the image signal corresponding to the maximum brightness value.
In a possible application scenario, as shown in fig. 3, the timing controller TCON in the display device may obtain externally input multi-frame image signals, divide the multi-frame image signals into at least one image signal group, each image signal group includes continuous multi-frame image signals, then the timing controller TCON may analyze brightness of all frame image signals in each image signal group to obtain maximum brightness values required for displaying all frame image signals in each image signal group, then the timing controller TCON may determine preset brightness intervals in which each maximum brightness value is located as corresponding target brightness intervals, and may search preset driving parameters (for example, preset Gamma (Gamma) voltages, preset common voltages (Vcom) and preset Analog Voltages (AVDD)) corresponding to each target brightness interval in a memory (for example, an EEPROM) in the display device, and then when the obtained multi-frame image signals need to be displayed, may sequentially display the preset Gamma (Gamma) voltages, the preset Gamma (Vcom) and the preset Analog Voltages (AVDD) may be written into the Power supply device according to the display sequence, and the preset driving parameters (Gamma) corresponding to the preset Gamma (video chips) and the preset voltages (AVDD) in the Power supply device may sequentially, the display panel in the display device is driven to display the images of all the frame image signals in the image signal group sequentially, wherein the frame image signals belong to the image signal group and the maximum brightness value corresponding to the preset driving parameter of the current writing Power chip Power IC are input by the timing controller TCON.
Therefore, the multi-frame images to be displayed are divided into a plurality of groups, and the gamma voltage, the public voltage and the analog voltage output by the power supply chip during displaying each group of images can be related to the maximum brightness value required by displaying the group of images, so that the display equipment can be driven to display each group of images by smaller gamma voltage and analog voltage during displaying each group of images, and the display power consumption of the display equipment is reduced.
In the above embodiment, as shown in fig. 2, after the step S13 and before the step S14, the image display method may further include:
s15: and compensating the brightness value of the pixel of the corresponding image signal according to the preset gamma voltage.
Accordingly, the above S14 may specifically be: and driving the display equipment to display the image of the corresponding compensated image signal according to the preset driving parameters.
Specifically, after determining the preset driving parameter corresponding to the maximum brightness value, the brightness compensation value corresponding to the preset gamma voltage included in the preset driving parameter may be obtained from a preset brightness compensation value lookup table, and the brightness value of the pixel (or the pixel unit) in the image signal (for example, all the frame image signals in the image signal group) to which the corresponding maximum brightness value belongs is compensated according to the brightness compensation value. The brightness compensation value lookup table may record the correspondence between a plurality of preset gamma voltages and a plurality of brightness compensation values.
In a specific embodiment, the brightness compensation value may include a brightness increment and/or a brightness decrement. Specifically, the compensating the brightness value of the pixel in the image signal to which the corresponding maximum brightness value belongs according to the brightness compensation value may specifically include: subtracting the brightness decrement from the brightness value of the pixel (for example, the pixel with the brightness value larger than the first preset brightness threshold value) with the excessively high brightness in the image signal to which the corresponding maximum brightness value belongs; and/or adding the brightness increment to the brightness value of the pixel with too low brightness (for example, the pixel with the brightness value smaller than the second preset brightness threshold value) in the image signal to which the corresponding maximum brightness value belongs.
Therefore, through carrying out brightness compensation on the too bright or too dark pixels in the image signals, the area with too high brightness in the image can be dimmed, the area with too low brightness is dimmed, and further the problem of image distortion caused by the change of gamma voltage output by the power chip along with the change of the maximum brightness value required by image display can be avoided.
As can be seen from the above, in the image display method in this embodiment, by obtaining an image signal and performing brightness analysis on the image signal, a maximum brightness value required for displaying the image signal is obtained, then a preset driving parameter corresponding to the maximum brightness value is determined, the preset driving parameter includes a preset gamma voltage, and the display device is driven to display an image of the corresponding image signal according to the preset driving parameter, so that the gamma voltage output by the power chip can be changed along with the brightness change of the image to be displayed, and further the display panel can be driven to display the image with a gamma voltage as small as possible while ensuring normal display of the image, so as to reduce the display power consumption of the display device (e.g., transparent display device).
