Referring to fig. 2, a first embodiment of the screen display method of the present invention includes:
step S10, obtaining the current backlight brightness of the screen of the display device, and generating the current display brightness of the screen according to the current backlight brightness;
in this embodiment, the implementation subject is a display device, and the display device refers to a device having a display function, such as a computer monitor, a television, a monitor, or a smart phone. The display device is generally a liquid crystal display screen, that is, a backlight plate is used as a main light source, and the arrangement of liquid crystal molecules is controlled to adjust the transmission or shielding of light emitted by the backlight plate, so as to display an image on the screen. And the obtained current backlight brightness of the screen is the backlight plate brightness of the display equipment. And after the backlight brightness is obtained, the current display brightness of the screen is generated continuously through the backlight brightness.
Further, the step of generating the current display brightness of the screen according to the current backlight brightness includes: inputting the current backlight brightness into a preset display brightness calculation formula, and taking a result output by the preset display brightness calculation formula as the current display brightness of a screen of the display device;
the preset display brightness calculation formula is as follows:
wherein, B L Is the current backlight brightness, L W Is the current display luminance and has the unit nit (nit).
Specifically, the current display brightness of the screen of the display device, for example, the backlight brightness B of the display device, can be obtained through the preset display brightness calculation formula L When the current display brightness is 100, the current display brightness L of the screen is obtained W 1000nit, so the screen current display brightness will have a linear relationship with the backlight brightness. And the resulting current display brightness of the screen will be used for subsequent brightness curve generation.
Optionally, before the step of obtaining the current backlight brightness of the screen of the display device, the method includes:
if the display equipment is in an automatic matching brightness mode, acquiring the current backlight brightness of a screen of the display equipment; and if the display equipment is in a manual regulation mode, receiving input backlight brightness, and taking the input backlight brightness as the current backlight brightness of the screen of the display equipment.
Specifically, before the backlight brightness of the display device is obtained, a user selects a mode of the display device, wherein the mode comprises an automatic matching brightness mode and a manual adjusting mode, and the automatic matching brightness mode directly obtains the current backlight brightness for the display device; the manual adjusting mode is that the user manually inputs the backlight brightness or the user directly adjusts the backlight brightness, and the backlight brightness input or adjusted by the user is used as the current backlight brightness. If the user watches a picture with 1000nit brightness for a long time, the user feels that the eyes are not comfortable to select the manual adjusting mode and manually adjusts the backlight brightness to be low (the display brightness of the screen is also reduced by adjusting the backlight brightness to be low), and at this moment, the display device acquires the user-adjusted backlight brightness and takes the user-adjusted backlight brightness as the current backlight brightness. In addition, in the prior art, the luminance curve of the display device is fixed, and after the user adjusts the backlight luminance, the display luminance and the luminance curve of the display device are not suitable, which may cause an unclear picture.
Further, the step of generating the current display brightness of the screen according to the current backlight brightness comprises: and displaying the generated current display brightness of the screen on the screen of the display device.
And when the display equipment is started or the brightness of the display equipment is adjusted by a user, displaying the generated numerical value of the current display brightness on a screen of the display equipment so that the user can adjust the brightness according to the displayed numerical value.
Step S20, generating a luminance curve corresponding to the current display luminance based on the current display luminance;
generating a parameter gamma of the brightness curve according to the current display brightness, wherein a generation formula of the parameter gamma is as follows:
wherein L is W The unit is nit and gamma is the parameter of the brightness curve; and determining a brightness curve corresponding to the current display brightness according to the parameter gamma.
In particular, if the current display brightness L is W At 1000nit, the above formula was substituted to obtain a parameter γ of 1.2. It can be understood that different current display luminances correspond to different parameters γ, and different display devices have different ranges of the display luminances, and correspondingly, the range of the parameter γ is also limited by the property of the display device itself, for example, if the minimum display luminance of the current display device is usually 100nit, and the corresponding parameter γ is about 0.78, the minimum parameter γ that can be determined by the display device is 0.78. In addition, the parameter γ is also called gain value, and is a parameter in a luminance curve, and when the picture signal received by the display device is the HLG signal, the luminance curve is also called HLG curve, and contains picture color luminance information, for representing the relationship between the picture color brightness in the HLG signal received by the display device and the plane-changing color brightness actually displayed by the display device based on the HLG signal, i.e., the color brightness received by the display device, and the color brightness actually output by the display device, and the color brightness may be classified into 256 levels of 0-255 according to the brightness level, if the display device receives a pixel with a color luminance of 150, based on the above HLG curve, it is possible to obtain that the color luminance 150 corresponds to the color luminance 165, and therefore the color luminance actually displayed by the pixel when the display device displays an image is 165, and actually the above 150 and 165 are also used to indicate the degree of shading of one pixel. The HLG curve is a standard luminance curve, that is, a unique HLG curve can be determined by using the parameter γ, and the parameter γ is based on the current display luminance of the display device, so that the finally obtained HLG curve actually corresponds to the current display luminance of the display device.
Optionally, before the step of generating the parameter γ of the luminance curve according to the current display luminance, the method includes: judging whether the current backlight brightness is the maximum backlight brightness of the display equipment; when the current backlight brightness is equal to the maximum backlight brightness, the current display brightness is a preset value; and when the current backlight brightness is not equal to the maximum backlight brightness, executing the step of inputting the current backlight brightness to a preset display brightness calculation formula.
And step S30, displaying the picture signal received by the display device based on the picture color brightness corresponding to the brightness curve.
Further, before the step of outputting the picture signal based on the display luminance corresponding to the luminance curve, the method includes: and obtaining the screen body color gamut of the display equipment, and converting and configuring the screen body color gamut of the display equipment into a standard color gamut of the picture signal based on preset color gamut mapping conversion parameters.
Specifically, when the picture signal is the HLG signal, the standard color gamut is the bt.2020 color gamut, and the color gamut of the display device is usually different according to the model or manufacturer of the device, so that the color gamut (screen body color gamut) used by the display device is different from the HLG signal. Correspondingly, the screen body color gamut of the display device is obtained, and the screen body color gamut of the display device is converted into the bt.2020 color gamut, wherein the specific conversion mode is that the screen body color gamut of the display device is multiplied by a preset color gamut mapping conversion parameter, that is, the screen body color gamut can be mapped to the bt.2020 color gamut, so that the color gamuts of the display device and the HLG signal are unified. Further, the gamut mapping conversion parameters are as follows:
wherein, X is a color gamut mapping conversion parameter, and a1, a2, a3, b1, b2, b3, c1, c2, and c3 can be obtained by technicians according to a screen color gamut and a standard color gamut test.
If a screen body color gamut of a certain display device is obtained and a color gamut mapping conversion parameter matrix X is obtained by combining the BT.2020 color gamut, the following steps are carried out:
if the standard screen color gamut coordinates are multiplied by the color gamut mapping conversion parameter matrix X, the standard color gamut coordinates of the bt.2020 color gamut can be obtained. The standard coordinates of the primary colors of the bt.2020 color gamut are shown in table 1.
TABLE 1
In the table, R is Red (Red), G Green (Green), B is Blue (Blue), W is White (White), and X, Y is the corresponding coordinate value.
Further, the picture signal received by the display device is displayed on the display device configured with the standard color gamut based on the picture color brightness corresponding to the brightness curve.
Specifically, the picture signal is an HLG signal, the display device displaying the HLG signal is configured to be a bt.2020 color gamut, and after receiving the luminance signal in the HLG signal, the display device may determine the color luminance of each pixel in the actually played picture according to an HLG curve (the HLG curve is a luminance display rule).
In this embodiment, the current display brightness of the display device is determined by obtaining the backlight brightness of the display device, and further a suitable brightness curve is determined according to the current display brightness, and the display device completes the playing of the picture signal based on the obtained brightness curve. It can be understood that, because the luminance curve is determined according to the current display luminance of the display device, it is ensured that the color luminance rule according to which the display device is based can be adapted to the real-time display luminance of the display device, thereby ensuring the quality of the display picture of the display device, realizing that the display device reacquires the current display luminance after reducing the display luminance and obtains a corresponding luminance curve, and maintaining the display effect when playing the HLG signal based on the luminance curve.
