Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims.
In order to solve the technical problems, embodiments of the present disclosure provide a pixel data processing method, a device, a display apparatus, and a storage medium. The pixel data processing method can be applied to display devices, and the display devices can include, but are not limited to, mobile phones, computers, tablets, electronic books, stereoscopic display screens, conference integrated machines, electronic whiteboards and other devices with display functions.
Referring to fig. 1, the display apparatus includes a timing control module, a pixel array, a scan signal driving module, and a data signal driving module. The timing control module (TCON) and the scan signal driving module (Gate Driver) may be implemented by circuits in related technologies, which are not described herein. Each Pixel unit (Pixel) in the Pixel array includes a light emitting device and a Pixel driving circuit for driving the light emitting device to emit light. The structure of the light emitting device of the pixel unit comprises various structures, and the light emitting device can be selected and set according to actual needs. For example, the light emitting device may be an OLED, a quantum dot light emitting diode (Quantum Dot Light Emitting Diodes, QLED for short), a Micro light emitting diode (Micro Light Emitting Diodes, micro LED for short), or the like, and may be selected according to a specific scenario, which is not limited herein.
The display device further comprises an IR-drop compensation function (not shown in the figures) which works on the principle that: when the IR voltage drop compensation function is started, the control voltage of each pixel point is compensated by combining the characteristic of line voltage drop, so that the control voltage of the same brightness of the pixel units in the same column or row is the same; when the IR voltage drop compensation function is turned off, the farther the distance from the data signal driving module is, the smaller the control voltage is, so that the farther the pixel unit and the data signal driving module are, the lower the brightness is.
In one embodiment, a data signal driving module (DDIC) may process pixel data of an image to be displayed and convert the pixel data into control voltages required by each column of pixel units; and the pixel unit is driven to emit light by the control voltage. In this embodiment, the data signal driving module may be configured to perform a pixel data processing method, see fig. 2, including steps 21 to 23.
In step 21, a present current threshold of the image to be displayed is acquired.
In this step, the data signal driving module of the display device may acquire an image to be displayed from the timing control module (TCON), and then acquire a current threshold of the image to be displayed, see fig. 3, including steps 31 to 32:
in step 31, obtaining attribute data of an image to be displayed, wherein the attribute data comprises window display proportion and brightness adjustment value of the image to be displayed; the window display proportion refers to the proportion of pixels in the image to be displayed, wherein the brightness value of the pixels exceeds a preset brightness threshold value.
Considering that the image to be displayed includes attribute data, for example, the attribute data may include a window display scale and a brightness adjustment value of the image to be displayed. The window display proportion refers to the proportion of pixels in the image to be displayed, wherein the brightness value of the pixels exceeds a preset brightness threshold value, and the proportion is a statistic value. For example, the image to be displayed comprises 100 pixel units, the brightness range of each pixel unit is 0-255, and the preset brightness threshold value is 200; counting that the brightness of 20 pixel units in the image to be displayed is between [201, 255] and exceeds 200; therefore, the window display ratio of the image to be displayed is 20/100×100+=20%. The brightness adjustment value refers to the brightness of the image to be displayed when displayed, for example, 0 to 2000nit.
The data signal driving module can analyze attribute data of the image to be displayed when the image to be displayed is acquired; alternatively, the data signal driving module may recalculate the attribute data, which is not limited herein.
In step 32, the product of the window display ratio and the brightness adjustment value is obtained as the current threshold of the image to be displayed.
In this step, the data signal driving module may obtain the product of the window display ratio and the brightness adjustment value, as a current threshold of the image to be displayed, that is, a current threshold=window display ratio.
In step 22, in response to the current threshold being greater than a preset current threshold, the pixel data of each pixel of the image to be displayed is adjusted to the target pixel data, and the IR-drop compensation function is turned off.
In the step, a preset current threshold value can be stored in the data signal driving module, the value range of the preset current threshold value can be [1200, 2000] nit, and the preset current threshold value can be set according to specific scenes; in an example, the preset current threshold has a value of 1400nit.
In the step, after the current threshold is obtained, the data signal driving module compares the current threshold with a preset current threshold to obtain the magnitude relation of the current threshold and the preset current threshold. When the current threshold is greater than the preset current threshold, the data signal driving module may adjust the pixel data of each pixel of the image to be displayed to the target pixel data in response to the current threshold being greater than the preset current threshold, see fig. 4, including steps 41 to 43.
In step 41, the present current threshold is updated to the preset current threshold.
Considering that when the current threshold exceeds the preset current threshold, the brightness adjustment value of the image to be displayed will exceed the brightness adjustment value of the image to be displayed, so that the power consumption of the display device becomes larger, the data signal driving module may modify the current threshold in this step, for example, update the current threshold to the preset current threshold, so that the current threshold takes a maximum value (i.e., the preset current threshold).
In step 42, a lookup table corresponding to the preset current threshold is obtained; the look-up table includes brightness curves at different window display scales with the IR drop compensation function turned off.
In this step, a Look-up Table (Look-up Table) is stored in the data signal driving module, and the Look-up Table includes brightness curves at different window display scales when the IR-drop compensation function is turned off. The look-up table is shown in fig. 5 in one example. Referring to fig. 5, a blue curve represents brightness curves at different window display scales with an IR drop compensation function and 1600nit brightness turned on, which is a straight line of inclination; the red curve represents the brightness curve at different window display ratios with the IR drop compensation function turned off and 1600nit brightness, which is a broken line with the inflection point at 25% of the window display ratio; the green curve represents the brightness curve at different window display ratios with the IR drop compensation function turned on and 1400nit brightness, which is a broken line with inflection point at 80% of window display ratio; the purple curve represents the brightness curve under different window display proportions under the condition of closing the IR drop compensation function and 1400nit brightness, and is a horizontal straight line; the light blue curve represents the brightness curve under different window display proportions under the conditions of opening the IR drop compensation function and 1200nit brightness, and is a horizontal straight line; the orange curve represents the luminance curve at different window display ratios with the IR drop compensation function turned off and the 1200nit luminance, and is a horizontal straight line.
It should be noted that, with continued reference to fig. 5, at least one luminance curve in the lookup table includes a curve portion for turning off the IPR voltage drop compensation function and a curve portion for turning on the IR voltage drop compensation function, and window display ratios corresponding to the switching IR voltage drop compensation functions of different luminance curves are different, or inflection points of at least one luminance curve in fig. 5 are different, and the inflection points approximate to an adjustment point of the current threshold under the current display luminance, so as to achieve the effect of adjusting the current threshold under different display luminance and window display ratios.
In this step, the data signal driving module may determine the required lookup table according to at least one of the current threshold, the brightness adjustment value and the window display ratio.
In step 43, pixel data corresponding to each pixel unit of the image to be displayed under the brightness curve is obtained as the target pixel data.
In this step, the data signal driving module may acquire pixel data corresponding to each pixel unit of the image to be displayed under the brightness curve; it can be understood that, before the current brightness threshold value is updated, the pixel data of each pixel unit corresponds to one brightness value; when the current brightness threshold is updated to a preset brightness threshold, the pixel data of each pixel unit is updated to another brightness value, for example, the pixel data before updating is multiplied by an adjustment coefficient (0 < K < 1) to reduce the brightness of each pixel unit, so that the data signal driving module can acquire the target pixel data in a table look-up mode.
In this step, the data signal driving module may generate a control instruction for turning off the IR drop compensation function, taking into account that the area with a smaller window display ratio in the image to be displayed is displayed with high brightness.
After the IR voltage drop compensation function is closed, the control voltage of each pixel unit is not required to be compensated, and the power consumption of the backboard can be reduced; in addition, due to the fact that voltage drop (IR drop) exists between different pixel units, contrast between a higher area and a darker area can be increased, and display quality is improved.
In an embodiment, when the current threshold is less than or equal to the preset current threshold, the data signal driving module does not correct the pixel data of each pixel unit of the image to be displayed, i.e. takes the pixel data as target pixel data, and keeps the IR-drop compensation function on.
In step 23, the target pixel data is output.
In this step, the data signal driving module may output the target pixel data, for example, convert the target pixel data from a digital signal form to an analog signal form, so as to write the target pixel data into each pixel unit, thereby achieving the effect of controlling the display of each pixel unit.
The scheme provided by the scheme of the embodiment can acquire the current threshold value of the image to be displayed; then, in response to the current threshold being greater than a preset current threshold, adjusting pixel data of each pixel of the image to be displayed to target pixel data, and turning off an IR drop compensation function; then, the target pixel data is output. Therefore, the current threshold is adjusted by adjusting and closing the IR voltage drop compensation function, so that the electronic equipment can be ensured to display the image under the smaller window display proportion by adopting the ultra-high brightness under the condition of low power consumption, and the use experience is improved.
The above pixel data processing method is described in connection with specific embodiments, including:
referring to fig. 6, in the present embodiment, it is assumed that the current threshold value is approximately equal to the window display scale. The data signal driving module can acquire an image RGB [11:0] to be displayed; then, the window display scale and the brightness adjustment value are evaluated. For example, the product of the window display proportion and the brightness adjustment value in the attribute data of the image to be displayed is obtained as a current threshold value, and then the current threshold value is compared with a preset current threshold value corresponding to the image to be displayed. And when the current threshold is larger than the preset current threshold, updating the current threshold to the preset current threshold. And then, the data signal driving module can acquire a lookup table corresponding to a preset current threshold value, and acquire pixel data corresponding to each pixel unit of the image to be displayed under a brightness curve as target pixel data. And, a control command to turn off the IR-drop compensation function is generated to turn off the IR-drop compensation function. Or if the current threshold is smaller than or equal to the preset current threshold, outputting the pixel data of each pixel unit as target pixel data.
Example 1
When there is no locally high brightness screen such as text browsing or reading APP, the screen may be as shown in fig. 7. Considering that the screen shown in fig. 7 is only for the purpose of expressing low brightness, the present disclosure performs a certain blurring process on the text in the screen shown in fig. 7.
The preset brightness threshold setting at this time is shown in fig. 8. Referring to fig. 8, when the brightness of the image to be displayed is 1200nits, the current brightness threshold exceeds the preset brightness threshold when the window display ratio is 60%, at this time, the brightness value of the adjusted image needs to be reduced, and the IR drop compensation function is turned off. When the brightness of the image to be displayed is 1000nits, the current brightness threshold exceeds the preset brightness threshold when the window display proportion is 72%, and at the moment, the brightness value of the image needs to be reduced and adjusted, and the IR voltage drop compensation function is turned off. When the brightness of the image to be displayed is 900nits, the current brightness threshold exceeds the preset brightness threshold when the window display proportion is 80%, and at the moment, the brightness value of the image needs to be reduced and adjusted, and the IR voltage drop compensation function is turned off. When the brightness of the image to be displayed is 800nits, the current brightness threshold exceeds the preset brightness threshold when the window display proportion is 90%, and at the moment, the brightness value of the image needs to be reduced and adjusted, and the IR voltage drop compensation function is turned off.
Example two
Referring to fig. 9, when the maximum brightness of the display device is 1400nit, a problem of local over-brightness and blurred pictures occurs as shown in a square frame area in fig. 9. In this embodiment, the maximum brightness of the display device can be increased to 2000nit, and in combination with the pixel data processing method described above, a brightness curve as shown at 10 is used,
referring to fig. 10, the display with ultra-high brightness is used in the partial 5% area, and the IR-drop function is turned off at this time, resulting in the image shown in fig. 11.
In this embodiment, due to the limitation of the back plate, a local higher luminance of 5% cannot be achieved at a display luminance of 1400nit, and a scheme of reducing the current threshold when the display luminance is 1600nit at a window display ratio of 100% may be considered. For example, assume that the power of a full white screen having a luminance of 1400nit is 4.5W and the power of a full white screen having a luminance of 1600nit is 6W at a window display ratio of 100%; in the embodiment, the power consumption can be reduced by 1.5W by adopting the current threshold value for the whole surface, the electric quantity is saved by nearly 1/3, and the service time of the brightness 1400nit of 1/3 times is prolonged.
