Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In recent years, the industrial application of OLED display screens is becoming more and more popular, and the OLED display screens are most remarkable in products such as mobile phones, media players and small entry televisions. The traditional OLED screen is often rectangular, the screen is composed of a plurality of pixels, the pixels are arranged on the screen in a matrix array mode, corresponding position coordinates are matched based on screen coordinate axes, and the display color and brightness of each pixel are determined through the mapping relation between the pixel coordinates and the image, so that the display of the image is realized.
In addition to rectangular screens, special-shaped screens other than rectangular screens have many application scenarios, such as rounded rectangular screens of mobile phones, circular screens of smart bracelets, and the like. In the present application, a profiled screen means a display screen in which the screen edge is non-straight or the screen corner is not right angle. In the process of realizing the special-shaped screen display, the inventor finds that the edge of the special-shaped screen is not straight or right-angled, and the saw-tooth bright line appears at the edge of the screen, so that the display effect is affected. Therefore, the application discloses the special-shaped screen display method, the special-shaped screen display device, the special-shaped screen display control equipment and the storage medium.
The special-shaped screen display method provided by the application can be applied to a display controller of a special-shaped screen, can be a built-in controller or a control circuit of the special-shaped screen based on different product forms, and can also be a control device or a circuit externally connected with the special-shaped screen for controlling the special-shaped screen to display images.
In one embodiment, as shown in fig. 1, there is provided a special-shaped screen display method, including the steps of:
step 100, obtaining initial brightness data of each pixel;
specifically, a pixel coordinate axis is arranged on the special-shaped screen and is used for positioning and displaying pixels. And acquiring initial brightness data of each pixel in the special-shaped screen, wherein the initial brightness data comprises coordinates of the pixel and corresponding brightness values.
Step 200, determining edge special-shaped pixels at the edges of the special-shaped screen; the display area of the edge special-shaped pixels is smaller than that of the conventional pixels;
specifically, as shown in fig. 2, the special-shaped screen is not straight or right-angled, the rectangular pixels cannot be completely matched with the edges of the screen, and a part of the pixels at the most edge cannot be arranged according to the area of the conventional pixels and can only be smaller than the conventional area. These pixels are edge shaped pixels, such as the diagonally shaded pixels of fig. 2.
Step 300, reducing the brightness data of each edge special-shaped pixel to obtain the display brightness data of each pixel;
specifically, the luminance data of the edge special-shaped pixels can be properly reduced according to a preset fixed value, the amount of the luminance data to be reduced can be judged according to the pixel position coordinates of each edge special-shaped pixel, and the luminance data to be reduced of each edge special-shaped pixel can be obtained according to the difference between the luminance of each edge special-shaped pixel and the luminance of the conventional pixel. And after the brightness data of the special-shaped pixels at each edge are reduced, combining the brightness data with the brightness data of other conventional pixels to obtain the display brightness data of all the pixels in the screen. Display luminance data, i.e. the method finally confirms the luminance data for the display image.
Step 400, displaying an image according to the display brightness data of each pixel.
Specifically, the image display of the special-shaped screen is performed according to the brightness data, color data and other data of each pixel. The display may be performed with reference to various conventional display methods.
The inventors have found that when solving the display problem of the zigzag bright lines at the edges of the screen, the OLED pixels are driven by a current source. The current density of the special-shaped pixels at the edges of the special-shaped screen is higher than that of the conventional pixels before the same driving current because the actual display area of the special-shaped pixels is smaller than that of the conventional pixels.
The above formula, where L is luminance, η is luminous efficiency (invariable), J is current density, I is current, and S is pixel area. It can be seen that as the pixel area S decreases, the current I and the luminous efficiency η do not change, and the luminance L increases. Thus, the display problem of the zigzag bright lines at the edges of the screen is caused by the higher brightness of the edge-shaped pixels than the conventional pixels.
So if the brightness L is desired to be unchanged, the pixel area S is proportional to the current I, and only the current I needs to be reduced. And the pixel luminance data and the pixel drive current are positively correlated.
In summary, in the method for displaying the special-shaped screen, initial brightness data of each pixel in the special-shaped screen is obtained first, edge special-shaped pixels with display areas smaller than those of conventional pixels are determined on the edges of the special-shaped screen, the brightness data of the edge special-shaped pixels are reduced, and the reduction of the driving current of the edge special-shaped pixels is equivalent to the reduction of the driving current of the edge special-shaped pixels, so that the display brightness of the edge special-shaped pixels is reduced, and sawtooth-shaped bright lines formed by the fact that the brightness of the edge special-shaped pixels is higher than that of the conventional pixels are eliminated, so that the display effect is better.
In one embodiment, the non-straight edge or non-right angle corner edge-most pixels of the shaped screen are identified as edge shaped pixels.
Of the shaped screens, the screen with edges or corner edges in an arc shape is most widely used. In one embodiment, as shown in fig. 3, the step of determining the edge special-shaped pixels at the edge of the special-shaped screen for any one arc edge includes:
step S210, acquiring circular arc center coordinates, a first threshold distance and pixel coordinates of each edge of the circular arc; the first threshold distance refers to the shortest distance from the circle center coordinates of the arc to each edge pixel on the arc edge;
the edge pixels are pixels on the arc edge of the special-shaped screen.
Specifically, the special-shaped screen is provided with at least one section of arc edge, and the area of each section of arc edge is a preset interval. The circle center coordinates of the arc at the edge of the arc can be obtained by the existing calculation mode according to the coordinates of the pixels at each edge on the arc. And (3) taking the circle center coordinates of the circular arc and the pixel coordinates of each edge into a distance formula to obtain the distance from each edge pixel to the circle center of the circular arc, and comparing to obtain the shortest distance, namely the first threshold distance of the edge of the circular arc. Preferably, the distance from each edge pixel to the circle center of the circular arc is the shortest distance from the outer edge of the edge pixel to the circle center of the circular arc. In one embodiment, the above division of each arc edge and the edge pixel coordinates, the arc center coordinates and the first threshold distance included in the division may be preset. The method can be preset in a memory or a data table, and can be inquired and obtained when the step is executed.
Step S220, calculating a target distance between the circle center coordinates of the circular arc and each edge pixel coordinate;
specifically, the coordinates of each edge pixel and the coordinates of the circle center of the circular arc are brought into a distance formula, and the target distance between the coordinates and the coordinates is obtained. Each edge pixel corresponds to a target distance and is used for judging whether the edge pixel is an edge special-shaped pixel or not. In one embodiment, as shown in FIG. 4, the screen coordinate system is arranged in pixel units, with edge pixels (x, y) and arc centers (x 0 ,y 0 ) By the formula Where a is the width of the pixel and b is the length of the pixel.
And step S230, screening out the edge special-shaped pixels from the edge pixels according to the first threshold distance and each target distance to obtain the coordinates of each edge special-shaped pixel.
According to the special-shaped screen display method provided by the embodiment, the special-shaped pixels of the edges are screened out from the edge pixels according to the target distance between all the edge pixels and the circular arc center coordinates and the first threshold distance. The edge special-shaped pixels can be judged more accurately, and the conventional pixels at the edge of the screen are prevented from being used as special-shaped pixels and are adjusted in brightness. And the display effect of the edge of the special-shaped screen is improved.
In one embodiment, the step of screening the edge special-shaped pixels from the edge pixels according to the first threshold distance and each target distance to obtain coordinates of each edge special-shaped pixel includes:
in step S231, for any one of the target distances, when the target distance is greater than or equal to the first threshold distance, the edge pixel corresponding to the target distance is an edge special-shaped pixel. The edge pixel coordinates are edge special-shaped pixel coordinates.
In one embodiment, as shown in fig. 4, the step of reducing the luminance data of each edge special-shaped pixel to obtain the display luminance data of each pixel includes:
step 310, obtaining brightness correction coefficients of the special-shaped pixels at each edge;
the brightness correction coefficient is used for reducing the brightness data of the edge special-shaped pixels, and the value range is between 0 and 1.
Step 320, according to the brightness data and brightness correction coefficient of each edge special-shaped pixel, brightness correction is carried out on each edge special-shaped pixel, and display brightness data of each edge special-shaped pixel is obtained;
in one embodiment, the product of the luminance data of each of the pixels having different shapes and the corresponding luminance correction coefficient is determined as the display luminance data of each of the pixels having different edges. In one embodiment, a difference between the luminance data of each of the pixels having different shapes and the corresponding luminance correction coefficient is determined as the display luminance data of each of the pixels having different edges. In one embodiment, the product of the brightness data of each special-shaped pixel and the corresponding brightness correction coefficient is added with a fixed brightness compensation value to obtain the display brightness data of each edge special-shaped pixel.
And 330, combining the display brightness data of each edge special-shaped pixel with the initial brightness data of the conventional pixel to obtain the display brightness data of each pixel.
And (3) combining the display brightness data of the special-shaped pixels at each edge with the initial brightness data of the conventional pixels acquired in the step 300 to obtain the display brightness data of each pixel on the special-shaped screen.
In one embodiment, the step of obtaining the brightness correction coefficient of each edge special-shaped pixel for any one arc edge includes:
step 311, obtaining a second threshold distance; the second threshold distance refers to the longest distance from the circle center coordinates of the arc to the edge of the arc;
the second threshold distance may be a preset value, and the call is looked up when executing this step.
Step 312, determining a correction reference value according to the difference between the second threshold distance and the first threshold distance;
specifically, the first threshold distance is the shortest distance from the circular arc center coordinates to each edge pixel on the circular arc edge, and the second threshold distance is the longest distance from the circular arc center coordinates to the circular arc edge. And the edge pixels with the distance between the circular arc center coordinates and the first threshold distance and the second threshold distance are just edge special-shaped pixels. Therefore, the difference between the second threshold distance and the first threshold distance is used as a correction reference value for the luminance correction coefficient.
Step 313, determining a correction value corresponding to each edge special-shaped pixel according to the difference value between the target distance corresponding to each edge special-shaped pixel and the first threshold distance;
the correction value represents the degree to which the edge special-shaped pixels need to be adjusted. The correction value may be equal to a difference of the target distance corresponding to the edge-shaped pixel minus the first threshold distance. In one embodiment, the correction value is equal to a difference of the target distance corresponding to the edge special-shaped pixel minus the first threshold distance plus a first preset adjustment factor. In one embodiment, the correction value is equal to a difference of the target distance corresponding to the edge special-shaped pixel minus the first threshold distance multiplied by a second preset adjustment factor.
Step 314, determining the brightness correction coefficient of each edge special-shaped pixel according to the quotient of dividing each correction value by the correction reference value.
Specifically, the correction value of any one of the edge abnormal pixels may be divided by the correction reference value of the edge abnormal pixel to obtain the luminance correction coefficient of the edge abnormal pixel. Optionally, the quotient of the correction value divided by the correction reference value is multiplied by, added to or subtracted from a third preset adjustment factor to obtain the brightness correction coefficient of each edge special-shaped pixel.
In one embodiment, as shown in fig. 5, the brightness correction coefficient of each edge profile pixel is calculated according to the following formula.
Where ratio represents a luminance correction coefficient, R represents a target distance, R1 represents a first threshold distance, and R2 represents a second threshold distance.
In one embodiment, the brightness correction coefficients of the edge special-shaped pixels are pre-stored in a memory, and the step of obtaining the brightness correction coefficients of the edge special-shaped pixels for any arc edge comprises:
step S315, according to the coordinates of each edge special-shaped pixel, the brightness correction coefficient of each edge special-shaped pixel is inquired from the memory.
Specifically, the brightness correction coefficients of the edge special-shaped pixels are preset in the memory, and when the step is executed, the brightness correction coefficients corresponding to the coordinates of the edge special-shaped pixels are queried in the memory. The implementation sets the brightness correction coefficient as a preset value, thereby effectively reducing the calculated amount of the method and improving the operation efficiency of the method.
In one embodiment, the brightness correction coefficients of the edge special-shaped pixels are pre-stored in a display lookup table, and the step of obtaining the brightness correction coefficients of the edge special-shaped pixels for any arc edge comprises:
step S316, according to the coordinates of each edge special-shaped pixel, the brightness correction coefficient of each edge special-shaped pixel is inquired from the display lookup table. Wherein a look-up table, LUT (LookUpTable) table, is displayed.
In one embodiment, the calculation of the preset data is performed before the special-shaped screen display method is performed, that is, before the step of acquiring the initial brightness data of each pixel, and the preset data is stored in the memory. Acquiring initial brightness data of each pixel, preset coordinates of each edge special-shaped pixel and preset brightness compensation coefficients of each edge special-shaped pixel, and multiplying the brightness data on the coordinates of each edge special-shaped pixel by the corresponding brightness compensation coefficients to obtain display brightness data of each edge special-shaped pixel; and combining the display brightness data of the special-shaped pixels at each edge with the brightness data of the conventional pixels to obtain the display brightness data of each pixel of the screen, and displaying the image. The coordinates of the preset edge special-shaped pixels and the preset brightness compensation coefficient of the edge special-shaped pixels can be obtained by referring to the calculation mode in the above embodiment, and will not be described herein.
