[ detailed description ] embodiments
The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive step are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of an image display method according to an embodiment of the present application, and a specific flow of the image display method may be as follows:
s11: an image signal is acquired.
In this embodiment, the 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 electrically erasable programmable read only memory), 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 display apparatus described above. 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 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, after the timing controller in the display device acquires the image signal, the brightness and darkness of the image signal may be analyzed to obtain the maximum brightness required for displaying the image signal.
In one embodiment, the maximum luminance value required for displaying the image signal may be a maximum luminance value required for displaying one frame of image signal. In addition, 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 number of pixel units may be taken as the vertical axis and the luminance value may be taken as the horizontal axis, a luminance histogram of the frame of image signal may be calculated, and then the maximum luminance value satisfying that the number of pixel units is greater than a preset number (for example, 25) may be taken as the maximum luminance value required for displaying the frame of image signal. For example, the numbers of pixel units having luminance values of I1, I2, and I3 are 20, 30, and 40, respectively, and I1 is smaller than I2, I2 is smaller than I3, and the preset number is 25, then the luminance values satisfying that the number of pixel units is larger than the preset number are I2 and I3, and the maximum luminance value satisfying that the number of pixel units is larger than the preset number is I3 because I2 is smaller than I3. In other embodiments, in order to obtain the maximum luminance value required for displaying a frame of image signal, the maximum value of the luminance values of all the pixel units in the frame of image signal may be used as the maximum luminance value required for displaying the frame of image signal, that is, the maximum luminance value is the luminance value of the pixel unit with the highest luminance in the frame of image signal.
In another embodiment, the number of the video signals may be multiple frames, and as shown in fig. 2, the 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 continuous multi-frame image signals.
Specifically, the timing controller in the above-described display apparatus may divide a plurality of frame picture signals into at least one picture signal group in frame order after acquiring the plurality of frame picture signals. The number of the video signals included in different video signal groups may be the same, for example, each video signal group may include video signals of a predetermined number of consecutive frames, where the predetermined number of frames is greater than 1 frame, and may be, for example, 10 frames.
S122: and performing brightness analysis on all the frame image signals in each image signal group to obtain the maximum brightness value required by display of all the frame image signals in each image signal group.
Specifically, in order to obtain the maximum luminance value required for displaying all the frame image signals in an image signal group, brightness analysis may be performed on each frame image signal in all the frame image signals in the image signal group, so as to obtain the single frame maximum luminance value required for displaying each frame image signal in the image signal group, and obtain a plurality of single frame maximum luminance values, and then the maximum value of the plurality of single frame maximum luminance values may be used as the maximum luminance 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 may be driven by a smaller gamma voltage to display the image, thereby avoiding a problem that when the brightness of the image to be displayed is low, the display device is driven by an excessively large gamma voltage to display the image, which may result in a large power consumption of a data driver of the display device, and reducing the display power consumption of the display device.
In a specific embodiment, as shown in fig. 2, the S13 may specifically include:
s131: and determining a preset brightness interval where 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 sections according to the magnitude or the luminance level, and each preset luminance section corresponds to a preset driving parameter. Moreover, after analyzing and obtaining the maximum brightness value required by the display of the image signal, the timing controller in the display device may use a preset brightness interval in which the maximum brightness value is located as a target brightness interval, and may obtain a preset driving parameter corresponding to the target brightness interval from a preset driving parameter lookup table.
The driving parameter lookup table may record a corresponding relationship between a plurality of preset luminance intervals and a plurality of preset driving parameters. Also, in some embodiments, each preset driving parameter may include a preset Gamma (Gamma) voltage, a preset common voltage (Vcom), a preset Analog Voltage (AVDD), and the like. Accordingly, the driving parameter lookup table may record a corresponding relationship between a plurality of preset luminance sections and a plurality of preset gamma voltages, a corresponding relationship between a plurality of preset luminance sections and a plurality of preset common voltages, and a corresponding relationship between a plurality of preset luminance sections and a plurality of preset analog voltages.
In an embodiment where the preset driving parameters include a preset gamma voltage, a preset common voltage and a preset analog voltage, for each preset driving parameter, an absolute value of a difference between the preset gamma voltage and the preset common voltage included in the preset driving parameter is in positive correlation with a corresponding maximum brightness value (or a preset brightness interval), that is, the smaller the maximum brightness value (or the brightness value in the preset brightness interval) is, 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 is. Further, each preset driving parameter includes a preset gamma voltage and a preset analog voltage, which are in positive correlation, 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 solved, 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 parameter.
Specifically, after the preset driving parameter corresponding to the maximum brightness value is determined, 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 may 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 acquire a plurality of frames of image signals input from the outside, and divide the plurality of frames of image signals into at least one image signal group, where each image signal group includes a plurality of consecutive frames of image signals, and then the timing controller TCON may perform brightness analysis on all the frames of image signals in each image signal group to obtain a maximum brightness value required for displaying all the frames of image signals in each image signal group, and then the timing controller TCON may determine a preset brightness interval in which each maximum brightness value is located as a corresponding target brightness interval, and may search for a preset driving parameter (e.g., a preset Gamma (Gamma) voltage, a preset common voltage (Vcom) and a preset Analog Voltage (AVDD)), then when the multi-frame image signal acquired by the Power chip is required to be displayed, the Power chip (Power IC) can write the values of the preset driving parameters corresponding to each maximum brightness value into the Power IC of the display device in sequence according to the display sequence (that is, the frame sequence), then the Power chip (Power IC) can output the preset Gamma (Gamma) voltage, the preset common voltage (Vcom) and the preset Analog Voltage (AVDD) to the Data Driver in the display device, and then the Data Driver (Data Driver) can output the preset Gamma (Gamma) voltage, the preset common voltage (Vcom) and the preset Analog Voltage (AVDD) according to the preset Gamma (Gamma) voltage, the preset common voltage (Vcom) and the preset Analog Voltage (AVDD) input by the Power chip (Power IC) and the signal group of all the frame image signals belonging to the maximum brightness value corresponding to the driving parameters currently written into the Power IC by the timing controller TCON And driving a display panel in the display device to sequentially display the images of all the frame image signals in the image signal group.
In this way, the multi-frame images to be displayed are divided into multiple groups, and the gamma voltage, the common voltage and the analog voltage output by the power supply chip when each group of images is displayed can be related to the maximum brightness value required by the group of images, so that the display equipment can be driven by the smaller gamma voltage and the smaller analog voltage to display each group of images when each group of images is displayed, 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 method for displaying an image 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 parameter.
Specifically, after the preset driving parameter corresponding to the maximum brightness value is determined, the brightness compensation value corresponding to the preset gamma voltage included in the preset driving parameter may be obtained from a pre-established 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 may be compensated according to the brightness compensation value. The brightness compensation value lookup table may record a corresponding relationship 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 with too high brightness (for example, the pixel with the brightness value larger than the first preset brightness threshold) in the image signal to which the corresponding maximum brightness value belongs; and/or adding 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 to the brightness increment.
Therefore, the brightness compensation is carried out on the pixels which are too bright or too dark in the image signal, the area with overhigh brightness in the image can be dimmed, the area with overlow brightness can be brightened, and the problem of image distortion caused by the fact that the gamma voltage output by the power supply chip changes along with the change of the maximum brightness value required by image display can be solved.
As can be seen from the above, in the image display method in this embodiment, the maximum brightness value required by the display of the image signal is obtained by obtaining the image signal and performing brightness analysis on the image signal, and then the preset driving parameter corresponding to the maximum brightness value is determined, where the preset driving parameter includes the preset gamma voltage, and the display device is driven according to the preset driving parameter to display the image corresponding to the image signal, so that the gamma voltage output by the power chip can change along with the brightness change of the image to be displayed, and further the display panel is driven by the gamma voltage as small as possible to perform the display of the image while ensuring the normal display of the image, so as to reduce the display power consumption of the display device (e.g., the transparent display device).
