Description

Display device and method for blurring boundary line in display lower lens device

The present invention generally relates to a display device, and a method of blurring boundary lines in a camera under display (CUD) device. In particular, the present invention is directed to a method for blurring the obvious boundary line between the sensor area and the display area in the display device by adjusting the gamma level of the pixel unit in a display lens device.

In order to obtain better display quality, the camera lens of the mobile phone can be advantageously designed to be hidden under the display panel. However, some light incident on the photographic lens may be blocked by the pixels, and the transparent materials of organic light-emitting diodes (OLEDs) are still too expensive to be used in common products.

To solve this problem, an incomplete sub-pixel layout can be proposed to hide the photographic lens under the panel. Additionally, in the panel, some pixels in the area showing the lower lens are cut out to facilitate the normal functioning of the photographic lens.

As shown in FIG. 1 , such an incomplete sub-pixel layout may cause a contour issue on the boundary line 11 of the display lower lens area 10 and the normal area 20 . FIG. 1 shows that there is an obvious visual difference between the under-display lens area 10 and the normal area 20 , that is, the visual existence of the boundary line 11 , so the presence of the under-display lens area 10 will endanger the panel 1 . Visual presentation quality.

In view of the above, a first aspect of the present invention proposes a novel display device, which can improve the visual presentation quality of the under-display lens device under the condition that the under-display lens area exists, for example, minimize the visual presence of the under-display lens area feel. In the case where the under-camera area is visually invisible, the boundary line will be blurred to hide the under-camera area. A second aspect of the present invention proposes a novel method to blur out the boundary lines in the under-display lens device to improve the visual presentation quality of the under-display lens device in the presence of the under-display lens region.

The display pixel group is disposed in the display area, adjacent to the blurred area, and has a display pixel luminance value DV.

The display pixel group includes n+m valid display pixels and no invalid display pixels. The blurred pixel group is disposed in a blurred area between the sensor pixel group and the display pixel group, and has a blurred pixel brightness value BV. Next, the display pixel luminance value DV is determined according to DV=[n/(n+m)]×100. Then, after the display pixel luminance value DV is determined, the blurred pixel luminance value BV is determined according to BV=(1-Z)×SV+Z×DV. Wherein, the minimum distance between the display pixel group and the sensor pixel group is 1, the minimum distance between the blurred pixel group and the sensor pixel group is Z, and the minimum distance between the blurred pixel group and the display pixel group is (1-Z).

Referring to FIG. 2 , step 101 is performed first. Step 101 is a step representing the input of a plurality of original pixel units. The original pixel units may be pixels or sub-pixels of the display device. The display device may correspond to the under-display lens device 100 shown in FIG. 3 . For example, there are a plurality of pixel units in the under-display lens device 100 . One pixel unit may be one pixel or one sub-pixel having a predetermined color and predetermined brightness. A pixel can include a plurality of sub-pixels, and each sub-pixel can emit light of a certain color, such as red (called R), green (called G), blue (called G), or another suitable color, but the present invention is not limited to this. In other words, step 101 can also be referred to as inputting R/G/B information.

Please refer to Figure 3. 3 illustrates a top view of a display lower lens device according to an example of the present invention. First, the under-display lens device 100 is provided. The under-display lens device 100 may include a display panel 101 for displaying pictures or images, such as the image 103 shown in FIG. 1 . The under-display lens device 100 may further include other suitable elements, such as an input unit (not shown), an output unit (not shown), or a control unit (not shown), but the present invention is not limited thereto. The display panel 101 may include a plurality of functional areas, such as a sensor area 110, a blurring area 120, and a display area 130, but the present invention is not limited thereto. In some embodiments of the invention, the sensor area 110 may be surrounded by a blurring area 120 and the blurring area 120 may be surrounded by a display area 130 . In some embodiments of the invention, the blurred region 120 may be in the form of an open circle 120H. The hollow circle 120H may include an inner concentric circle 121 and an outer concentric circle 122 . The inner concentric circle 121 may have the center 111 of the inner concentric circle 121 , so that the center 111 may also be the center of the outer concentric circle 122 .

The display panel 101 may include an image sensor 112 disposed in the sensor area 110 . The image sensor 112 may be disposed at least partially in the sensor area 110 , or completely disposed in the sensor area 110 . The image sensor 112 can be used as a photographic lens in the display lower lens device 100 .

As previously mentioned, there are a plurality of pixels or sub-pixels in the display device 100 . Different pixels or different sub-pixels in different regions of the display device 100 may form different pixel sets. In some embodiments of the present invention, at least one sensor pixel group 113 may be disposed in the sensor area 110 adjacent to the location of the blurred area 120 . In other words, the sensor pixel group 113 can be arranged inside the same The central circle 121, that is, the boundary line between the sensor area 110 and the blurred area 120, is located. The sensor pixel group 113 may include one or more sensor pixel units. FIG. 4 shows that the sensor pixel group 113 may include a plurality of sensor sub-pixels, but the present invention is not limited thereto.

In some embodiments of the present invention, at least one blurred pixel group 123 may be disposed in the blurred area 120 . In other words, the blurred pixel group 123 may be arranged between the inner concentric circle 121 and the outer concentric circle 122 , that is, may be arranged between the sensor area 110 and the display area 130 . The blurred pixel group 123 may include one or more blurred pixel units. FIG. 4 shows that the blurring pixel group 123 may include a plurality of sensor sub-pixels, but the present invention is not limited thereto.

In some embodiments of the present invention, at least one display pixel group 133 may be disposed in the display area 130 adjacent to the position of the blurred area 120 . For example, the display pixel group 133 may be disposed at the outer concentric circle 122 , that is, the boundary line between the display area 130 and the blurred area 120 . Display pixel group 133 may include one or more display pixel units. FIG. 4 shows that the display pixel group 133 may include a plurality of display sub-pixels, but the present invention is not limited thereto.

In some embodiments of the present invention, there may also be a straight line 102 passing through the sensor pixel group 113 , the blurring pixel group 123 , and the display pixel group 133 . In some embodiments of the present invention, the straight line 102 may further pass through the center 111 of the inner concentric circle 121 , the sensor pixel group 113 , the blurred pixel group 123 and the display pixel group 133 , so that the blurred pixel group 123 can be set in the sensor pixel group 123 between the detector pixel group 113 and the display pixel group 133 . The blurred pixel group 123 may include one or more blurred pixel units. In some embodiments of the present invention, FIG. 4 shows that the minimum distance between the display pixel group 133 and the sensor pixel group 113 is 1, and the minimum distance between the blurring pixel group 123 and the sensor pixel group 113 is Z, and the minimum distance between the blurred pixel group 123 and the display pixel group 133 is (1-Z).

FIG. 4 is a partial enlarged view of the display lens device 100 of FIG. 3 along the line 102 according to the present invention. The sensor pixel group 113 may include one or more sensor pixel units to form a unit unit cell. In one embodiment of the present invention, active sensor pixels and inactive sensor pixels in the sensor area 110 may form a pattern together, or may be regularly arranged. A unit unit including valid sensor pixels and invalid sensor pixels to represent a minimal repeating unit of a pattern or arrangement is represented by one of the sensor pixel groups 113 . For example, the sensor pixel group 113 may include n active sensor pixels and m inactive sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1. In another embodiment of the present invention, FIG. 4 shows that the sensor pixel group 113 may include four sensor sub-pixels, ie, n+m=4, but the present invention is not limited thereto. For example, sensor pixel group 113 may include sensor sub-pixel 114, sensor sub-pixel 115, sensor sub-pixel 116, and sensor sub-pixel 117, but regardless of the color of the four sensor sub-pixels why.

Similarly, blurred pixel group 123 may include one or more blurred pixel units to form a unit of cells. The number of blurring pixel units in one unit unit is the same as the number of sensor pixel units in one unit unit. For example, FIG. 4 illustrates that blurring pixel group 123 may include four blurring sub-pixels to correspond to the four sensor sub-pixels in sensor pixel group 113, regardless of the color of the four blurring sub-pixels why. For example, the blurring pixel group 123 may include blurring sub-pixels 124, blurring sub-pixels 125, blurring sub-pixels 126, and blurring sub-pixels 127, but the present invention is not limited thereto.

Similarly, display pixel group 133 may include one or more display pixel units to form a unit of cells. The number of blurred pixel units in one unit is the same as the number of display pixel units in one unit. For example, FIG. 4 illustrates that display pixel group 133 may include four display sub-pixels to correspond to the four sensor sub-pixels in sensor pixel group 113, regardless of the colors of the four display sub-pixels. For example, one display pixel group 133 may include display sub-pixels 134, display sub-pixels 135, display sub-pixels 136, and display sub-pixels 137, but the present invention is not limited thereto.

As described above, the image sensor 112 is provided in the sensor area 110, and a pixel unit occupied by a part of the image sensor 112 can be a pinhole (represented by a dot) to allow incident The light reaches the image sensor 112 to form part of the image. Due to the presence of one or more pinholes (ie, one or more dots represented by the lower lens area 10 in FIG. 1 ), since these invalid sensor pixel cells corresponding to dots are no longer able to emit light, the sensing One or more sensor pixel cells in the sensor area 110 may become invalid sensor pixel cells. FIG. 1 shows a region corresponding to the sensor region 110 in the form of dots in visual form, which may correspond to the pinholes of the invalid sensor pixel units.

Therefore, the sensor region 110 including the image sensor 112 may visually exhibit some valid sensor pixels and some invalid sensor pixels. An active sensor pixel can be represented as a sensor pixel unit capable of emitting light of any suitable color. An invalid sensor pixel may be represented as a sensor pixel cell that cannot emit light at all. For example, an invalid sensor pixel may be represented as a pixel cell represented by image sensor 112 in sensor region 110, occupied by a pinhole, such that the sensor pixel cell's Function not working. A collection of invalid sensor pixels in sensor area 110 may adversely alter the predetermined visual appearance of a given pattern, as shown in FIG. 1 .

Because an invalid sensor pixel has no brightness (no illumination available), based on the presence of invalid sensor pixels in sensor pixel group 113, sensor pixel group 113 (ie, a unit) total brightness. The more invalid sensor pixels there are, the smaller the total brightness of the sensor pixel group 113 will be.

To balance the reduction in illumination due to the presence of invalid sensor pixels, all valid sensor pixels in sensor pixel group 113 may have the largest sensor pixel luminance value SV, while sensor pixel group 113 All invalid sensor pixels in will have the smallest sensor pixel brightness value of 0. The maximum pixel luminance value may represent a maximum grayscale 255 equal to 100% of the intensity. The minimum pixel luminance value may refer to the minimum grayscale 0 that is equal to 0% of the intensity. Due to the concept of grayscale or intensity, in this technology It is well known in the art and therefore its details will not be described in detail. In other words, the luminance value of a sensor pixel unit can be SV or 0, so SV can be equal to the luminance value of 100.

Accordingly, the present invention provides the following procedures to mitigate or further eliminate the detrimental visual disturbance of inactive sensor pixels in sensor region 110 . First, as shown in FIG. 2 , step 201 is performed. First determine the display pixel brightness value DV. The display pixel brightness value DV is preferably related to the sensor pixel brightness value SV.

Due to the presence of one or more pinholes, not every sensor pixel unit in sensor area 110 is an active sensor pixel. On the contrary, the display pixel group 133 is arranged in the display area 130 as a general display area, so each display pixel unit in the display area 130 can emit any suitable color in the absence of invalid display pixels. of light for an effective display pixel. In some embodiments of the invention, if sensor pixel group 113 includes n active sensor pixels and m inactive sensor pixels, then display pixel group 133 may similarly and accordingly include n+m Valid display pixels and no invalid display pixels.

In order to show visual uniformity, the visual brightness of the display pixel group 133 is preferably close to or equal to the visual brightness of the sensor pixel group 113, so the display pixel brightness value DV can be determined. For example, the display pixel brightness value DV may decrease proportionally with respect to the sensor pixel brightness value SV. The sensor pixel brightness value SV can represent the result corresponding to the displayed lens.

If the sensor pixel group 113 includes n valid sensor pixels and m invalid sensor pixels, it can be determined according to the principle of DV=[n/(n+m)]×(maximum pixel brightness value SV) Determines the display pixel brightness value DV of the display pixel unit. For example, if SV is set to 100, then DV=[n/(n+m)]×100. The display pixel brightness value DV satisfying the aforementioned relationship can ensure visual brightness consistency with respect to the brightness in the display area 130 relative to the sensor area 110 . After the aforementioned steps, for example, the brightness of the display pixel units in the display area 130 can be made uniform and normalized (normalize), so they can share the same display pixel brightness value DV and have uniform brightness in the display area 130 . Therefore, the display pixel brightness value DV can represent the normal result or the normalized result.

Next, as shown in FIG. 2 , after step 201 is performed, step 301 is performed. After the display pixel brightness value DV of the display pixel unit is determined, the blurred pixel brightness value BV of the blurred pixel unit is determined. The way of determining the brightness value BV of the blurred pixel may be the brightness alignment of the brightness value BV of the blurred pixel from the maximum sensor pixel brightness value SV to the display pixel brightness value DV. This is an adjustment operation for the blurring area 120, relative to the sensor area 110 and relative to the display area 130, for brightness alignment.

Differently, in order to balance the luminance difference of the pixel units between the sensor area 110 and the display area 130, the illumination, eg, the luminance of each blurred pixel unit in the blurred area 120, may be based on the display pixel luminance value DV and the sensor. The detector pixel brightness value SV, and there is a specific blurred pixel brightness value BV. For example, the blurred pixel brightness value BV will be no greater than the maximum sensor pixel brightness value SV and no less than the corresponding display pixel brightness value DV, so as to form a smooth brightness gradient from SV to DV. Accordingly, a luminance gradient of pixel cells can be formed along line 102 such that the poor visual presentation of a given image caused by invalid sensor pixels in sensor region 110 can be gradually weakened and gradually reduced through blurring region 120 Convergence to display area 130 . In other words, the luminance gradient of the pixel unit can be used to blur the under-display lens area, such as the obvious boundary line 11 shown in FIG. 1, so that the original boundary line may become less obvious visually , or further become virtually invisible.

The blurred pixel group 123 forming a unit unit is disposed in the blurred region 120 and located between the sensor pixel group 113 and the display pixel group 133 , eg, just between the sensor pixel group 113 and the display pixel group 133 . Each pixel unit in the blurred pixel group 123 has an independent blurred pixel Brightness value BV. Each independent blurred pixel luminance value BV is calculated to align with SV and DV. The brightness value BV of each blurred pixel is determined so that the boundary line of the inner concentric circle 121 becomes blurred. A unit unit may include n+m sub-pixels regardless of the color of the sub-pixels, and may be arranged in a pattern or in sequence, eg, by their locus.

For example, a unit unit in the sensor pixel group 113 may include n valid sensor pixels and m invalid sensor pixels, where n is an integer not less than 1, and m is an integer not less than 1, so One unit unit may accordingly include n+m blurred pixels located in one blurred pixel group 123 , or may accordingly include n+m display pixels located in the display area 130 . A certain blurring pixel in one unit unit may correspond exclusively to a specific sensor pixel and to a specific display pixel. For example, the blurred pixel of the first point in one cell unit may correspond to the sensor pixel of the first point in another cell unit along line 102, and correspond to the first point of the other cell unit Display pixels for the site. And the blurred pixel of the second position in one unit unit may correspond to the sensor pixel of the second position in another unit unit along the line 102, and correspond to the second position in the other unit unit Display pixels for dots, and so on.

Then, as shown in FIG. 2 , step 401 is executed after step 301 is executed. Step 401 may be an adjustment calculation, such as performing one or more weighting calculations. This weighting calculation may involve one or more weights. The one or more weights may relate to dimensional measurements such as distance, so that the brightness of the sub-pixels in the blurred region 120 may be adjusted according to the distance to the reference point, although the invention is not so limited.

For example, a specific blurred pixel brightness value BV can be determined according to the weight Z, according to the corresponding sensor pixel brightness value SV, and according to the corresponding display pixel brightness value DV, and satisfy a linear weighting calculation: BV= (1-Z)×SV+Z×DV, but the present invention is not limited to this. The blurred pixel brightness value BV may represent the gamma level (gamma) of the blurred pixels in the blurred pixel group 123. level), but the present invention is not limited thereto. Along line 102, the minimum distance between a display pixel group 133 and a sensor pixel group 113 is 1, and the minimum distance between a blurring pixel group 123 and a sensor pixel group 113 is Z and is used as The weight in this example, and the minimum distance between one blurring pixel group 123 and one display pixel group 133 is (1-Z), but the present invention is not limited thereto. When implementing the method of the present invention, the actual minimum distance between the display pixel group 133 and the sensor pixel group 113 is obtained according to the actual situation at the time of implementation, and can be determined by those skilled in the art, as long as the minimum distance is sufficient It is sufficient to implement the present invention. In other words, the present invention introduces a weight value related to the display lens to determine the brightness value BV of the blurred pixel, but the present invention is not limited thereto.

2的實施方式，都要視為落入本發明的範圍之中和優化的原理之內。 As shown in FIG. 4 , some calculation examples for determining different brightness values BV of blurred pixels are proposed below according to some implementations of the present invention. Although the following calculation examples relate to the implementation of n+m=4, the present invention is not limited to the implementation of n+m=4. Anything involving n+m

2, are considered to fall within the scope of the present invention and within the principles of optimization.

first instance

FIG. 4 shows the sensor pixel group 113 including the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116, and the fourth sensor sub-pixel 117, so as to One unit of cells 113 is formed regardless of the color of the four sensor sub-pixels. The four sensor sub-pixels are arranged in a unit of cells with respect to their respective specific sites. A site refers to arranging a particular sensor sub-pixel along a given line, at a location in a given unit unit, or performing a determination of a pixel brightness value, such as DV or BV, a place of concern at times. For example, the sensor pixel group 113 including the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116, and the fourth sensor sub-pixel 117 may include four corresponding sites, such as the site of the first sensor sub-pixel 114, the site of the second sensor sub-pixel 115, the third sensor sub-pixel 116 , and the fourth sensor sub-pixel 117 , but the present invention is not limited thereto. In the first example, the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116 are active sensor pixels, and the fourth sensor sub-pixel 117 is inactive sensor pixels, so n=3 and m=1.

First, according to the aforementioned principle, the first sensor sub-pixel 114, the second sensor sub-pixel 115 and the third sensor sub-pixel 116 have the maximum sensor pixel brightness value SV (brightness 100) and the fourth sensor sub-pixel 116 respectively. The sensor sub-pixel 117 has the smallest sensor pixel luminance value of zero. The aforementioned initial conditions can be simplified and expressed as [sub-pixels (corresponding luminance values)]: [114(100), 115(100), 116(100), 117(0)]

4 shows the display pixel group 133 including the first display sub-pixel 134, the second display sub-pixel 135, the third display sub-pixel 136, and the fourth display sub-pixel 137 to form a unit 133, and the The colors of the four display subpixels are irrelevant. The four display sub-pixels are respectively arranged in a unit with respect to their specific sites. Then, according to DV=[n/(n+m)]×100, the display pixel luminance value DV of the four display sub-pixels is determined.

DV134=[3/(3+1)]×100=75 because the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114; DV135=[3/(3+1)]×100 =75 because the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115; DV136=[3/(3+1)]×100=75 because the third display sub-pixel 136 is in area Corresponds to the third sensor sub-pixel 116; DV137=[3/(3+1)]×100=75, since the fourth display sub-pixel 137 corresponds in area to the fourth sensor sub-pixel 117.

The above result can be simplified to: [134(75), 135(75), 136(75), 137(75)]

Third, FIG. 4 shows a blurred pixel group 123 including a first blurred sub-pixel 124, a second blurred sub-pixel 125, a third blurred sub-pixel 126, and a fourth blurred sub-pixel 127 to form a The unit is 123, regardless of the color of the four blurred sub-pixels. The four display sub-pixels are respectively arranged in a unit with respect to their specific sites. Assuming Z=0.25, which means that the blurred pixel group 123 is relatively close to the sensor pixel group 113 to determine the blurred pixel brightness value BV1 or BV2 of each blurred sub-pixel, and satisfy the relationship: BV=(1-Z )×SV+Z×DV. The first blurred pixel luminance value BV1 and the second blurred pixel luminance value BV2 may respectively represent a gamma level.

BV124=(1-0.25)×100+0.25×75=93.75 because the first blurred sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV=100); BV125=(1-0.25) ×100+0.25×75=93.75 because the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV=100); BV126=(1-0.25)×100+0.25×75= 93.75 because the third blurring sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV=100); BV127=(1-0.25)×0+0.25×75=18.75 because the fourth blurring Subpixel 127 corresponds in area to fourth sensor subpixel 117 (SV=0).

The above adjustment results can be simplified as: [124(93.75), 125(93.75), 126(93.75), 127(18.75)]

The calculation results are shown in Figure 5.

Note that because the total luminance in each cell unit 113/123/133 is the same (300), this results in a uniform visual luminance quality across different pixel groups.

Second instance

FIG. 4 shows the sensor pixel group 113 including the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116, and the fourth sensor sub-pixel 117, so as to One unit of cells 113 is formed regardless of the color of the four sensor sub-pixels. The four sensor sub-pixels are respectively arranged in a unit with respect to their specific sites. While in the second example, the first sensor subpixel 114 and the fourth sensor subpixel 117 are active sensor pixels, while the second sensor subpixel 115 and the third sensor subpixel 116 are Invalid sensor pixels, so n=2 and m=2.

First, according to the aforementioned principles, the first sensor sub-pixel 114 and the fourth sensor sub-pixel 117 have the maximum sensor pixel brightness value SV (brightness 100), respectively, while the second sensor sub-pixel 115 and the third sensor sub-pixel 115 have The sensor sub-pixels 116 each have the smallest sensor pixel luminance value of zero. The aforementioned initial conditions can be simplified as [sub-pixels (corresponding luminance values)]: [114(100), 115(0), 116(0), 117(100)]

4 shows the display pixel group 133 including the first display sub-pixel 134, the second display sub-pixel 135, the third display sub-pixel 136, and the fourth display sub-pixel 137 to form a unit 133, and the The colors of the four display subpixels are irrelevant. The four display sub-pixels are respectively arranged in a unit with respect to their specific sites. Then, according to the principle of DV=[n/(n+m)]×100, the display pixel brightness values DV of the four display sub-pixels are determined.

DV134=[2/(2+2)]×100=50 because the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114; DV135=[2/(2+2)]×100 =50 because the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115; DV136=[2/(2+2)]×100=50 because the third display sub-pixel 136 is in area corresponding to the third sensor sub-pixel 116; DV137=[2/(2+2)]×100=50 because the fourth display sub-pixel 137 corresponds in area to the fourth sensor sub-pixel 117 .

The above result can be simplified to: [134(50), 135(50), 136(50), 137(50)]

Third, FIG. 4 shows a blurred pixel group 123 including a first blurred sub-pixel 124, a second blurred sub-pixel 125, a third blurred sub-pixel 126, and a fourth blurred sub-pixel 127 to form a The unit is 123, regardless of the color of the four blurred sub-pixels. The four blurring sub-pixels are respectively arranged in a unit with respect to their specific positions. Assuming Z=0.50, this means that the blurring pixel group 123 is located equidistant from the sensor pixel group 113 and the display pixel group 133 . Then, the blurred pixel brightness value BV of each blurred sub-pixel is determined according to BV=(1-Z)×SV+Z×DV.

BV124=(1-0.50)×100+0.50×50=75, because the first blurred sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV=100); BV125=(1-0.50) ×0+0.50×50=25, because the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV=0); BV126=(1-0.50)×0+0.50×50= 25 because the third blurred sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV=0); BV127=(1-0.50)×100+0.50×50=75 because the fourth blurred Subpixel 127 corresponds in area to fourth sensor subpixel 117 (SV=100).

The above adjustment results can be simplified as: [124(75), 125(25), 126(25), 127(75)]

The calculation results are shown in FIG. 6 .

Note that because the total luminance in each cell unit 113/123/133 is the same (200), this results in a uniform visual luminance quality across different pixel groups.

Third example

FIG. 4 shows the sensor pixel group 113 including the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116, and the fourth sensor sub-pixel 117, so as to One unit of cells 113 is formed regardless of the color of the four sensor sub-pixels. The four sensor sub-pixels are respectively arranged in a unit with respect to their specific sites. While in the third example, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 are inactive sensor pixels, and the fourth sensor sub-pixel 117 is the active sensor pixel, so n=1 and m=3.

First, according to the aforementioned principle, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 have the smallest sensor pixel brightness value of 0, respectively, and the fourth sensor sub-pixel The sensor subpixel 117 has a maximum sensor pixel luminance value SV (luminance 100). The aforementioned initial conditions can be simplified as [sub-pixels (corresponding luminance values)]: [114(0), 115(0), 116(0), 117(100)]

4 shows the display pixel group 133 including the first display sub-pixel 134, the second display sub-pixel 135, the third display sub-pixel 136, and the fourth display sub-pixel 137 to form a unit 133, and the The colors of the four display subpixels are irrelevant. The four display sub-pixels are respectively arranged in a unit with respect to their specific sites. Then, according to DV=[1/(1+3)]×100, the display pixel brightness value DV of the four display sub-pixels is determined.

DV134=[1/(3+1)]×100=25, because the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114; DV135=[1/(3+1)]×100=25 because the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115; DV136=[1/(3+1)]×100 =25 because the third display sub-pixel 136 corresponds in area to the third sensor sub-pixel 116; DV137=[1/(3+1)]×100=25 because the fourth display sub-pixel 137 is in area Corresponds to the fourth sensor sub-pixel 117 .

The above result can be simplified to: [134(25), 135(25), 136(25), 137(25)]

Third, FIG. 4 shows a blurred pixel group 123 including a first blurred sub-pixel 124, a second blurred sub-pixel 125, a third blurred sub-pixel 126, and a fourth blurred sub-pixel 127 to form a The unit is 123, regardless of the color of the four blurred sub-pixels. The four blurring sub-pixels are respectively arranged in a unit with respect to their specific positions. Assuming Z=0.75, which means that the blurred pixel group 123 is located closer to the display pixel group 133, and then the blurring of each blurred sub-pixel is determined according to the principle of BV=(1-Z)×SV+Z×DV Pixel brightness value BV.

BV124=(1-0.75)×0+0.75×25=18.75 because the first blurred sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV=0); BV125=(1-0.75) ×0+0.75×25=18.75 because the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV=0); BV126=(1-0.75)×0+0.75×25= 18.75 because the third blurring sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV=0); BV127=(1-0.75)×100+0.75×25=43.75 because the fourth blurring Subpixel 127 corresponds in area to sensor subpixel 117 (SV=100).

The above adjustment results can be simplified as: [124(18.75), 125(18.75), 126(18.75), 127(43.75)]

The calculation results are shown in Figure 7.

Note that because the total luminance in each cell unit 113/123/133 is the same (100), this results in a uniform visual luminance quality across different pixel groups.

Next, as shown in FIG. 2 , step 501 is executed after step 401 is executed. For example, the brightness of each pixel unit in the blurred area 120 is determined, and a weighted result of each pixel unit in the blurred area 120 is obtained. The weighted result newly obtained by the pixel units in the blurring area 120 can represent the gradient used to weaken the contour, so as to blur the obvious boundary line of the lower lens area as shown in FIG. 1 . For example, in the first example, the brightness of some illustrated pixel units in the blurred area 120 is determined to obtain a weighted result of the pixel units in the blurred area 120 [124(93.75), 125(93.75), 126(93.75 ), 127(18.75)]. In a second example, the brightness of some of the instantiated pixel units in the blurred area 120 is determined to obtain a weighted result of the pixel units in the blurred area 120 [124(75), 125(25), 126(25), 127(75)]. And in the third example, the brightness of some of the pixel units in the blurred area 120 is determined to obtain the weighted result of the pixel units in the blurred area 120 [124(18.75), 125(18.75), 126(18.75) , 127(43.75)].

The weighting result of the pixel unit group is a set of each weighting result corresponding to each pixel unit in the blurring area 120 . For example, the set in the first instance is [124(93.75), 125(93.75), 126(93.75), 127(18.75)], and the set in the second instance is [124(75), 125(25), 126 (25), 127(75)], the set in the third example is [124(18.75), 125(18.75), 126(18.75), 127(43.75)]. each pixel cell located in the blurring region 120 with a weighted result on luminance, Then it becomes the adjusted pixel unit corresponding to the relevant pixel unit in the different area. For example, in the first example [114(100)-124(93.75)-134(75)] together with the first sensor sub-pixel (display lower lens) 114 and with the normal first display sub-pixel 134, form Adjusted first blurred sub-pixel 124. In the second example, [115(0)-125(25)-135(50)] together with the first sensor sub-pixel (display lower lens) 115 and with the normal first display sub-pixel 135, form an adjustment passed first blurred sub-pixel 125. In the third example, [117(100)-127(43.75)-137(25)] together with the first sensor sub-pixel (display lower lens) 117 and with the normal first display sub-pixel 137, form an adjustment past first blurred sub-pixel 127. The results of the improved luminance gradient are shown in the first example, the second example, or the third example, respectively.

After the foregoing steps, as shown in FIG. 2 , step 601 is executed to output a plurality of adjusted pixel units. Each and each RGB sub-pixel (referred to as R/G/B information) obtained after the aforementioned steps on the display panel 101 is output. R/G/B information, in terms of brightness, can include different types of information, but not their respective color information. For example, the R/G/B information in the sensor area 110 may relate to the original display lens results, such as the maximum pixel brightness value SV or the minimum pixel brightness value 0. The R/G/B information in the display area 130 may relate to a general result, such as the average display pixel brightness value obtained according to DV=[n/(n+m)]×(maximum pixel brightness value SV) DV. The R/G/B information in the blurring area 120 may involve a set of multiple gradient results, such as a set of blurred pixel brightness values BV obtained according to BV=(1-Z)×SV+Z×DV . Z is a variable corresponding to the position of a given blurred pixel unit.

In particular, the blurred pixel brightness value BV is a weighted result according to Z, and each weighted result corresponding to each pixel unit in the blurred area 120 is collected, so all the weighted results become in the blurred area In 120, a set of luminance information related to all pixel units for outputting a plurality of adjusted pixel units for display purposes.

After the aforementioned adjustment method, a novel display device 100 is provided to optimize the visual presentation quality of the display lower lens device under the condition that the display lower lens area exists, for example, to minimize the visual presence of the display lower lens area . 3 illustrates a top view of a display lower lens device according to an example of the present invention. FIG. 4 is a partial enlarged view of the display lens device according to FIG. 3 along a straight line. The display device 100 of the present invention includes a display panel 101 , an image sensor 112 , a sensor pixel group 113 , a display pixel group 123 , and a blurring pixel group 133 .

The display device 100 may be a device in which a photographic lens is disposed below the display panel. The under-display lens device may include a display panel 101 for displaying pictures or images (eg, images 103 ). The under-display lens device may further include other suitable elements, such as an input unit (not shown), an output unit (not shown), or a control unit (not shown), but the present invention is not limited thereto.

The display panel 101 may include a plurality of functional areas, such as a sensor area 110, a blurring area 120, and a display area 130, but the present invention is not limited thereto. In some embodiments of the invention, the sensor area 110 may be surrounded by a blurring area 120 and the blurring area 120 may be surrounded by a display area 130 . In some embodiments of the invention, the blurred region 120 may be in the form of an open circle 120H. The hollow circle 120H may include an inner concentric circle 121 and an outer concentric circle 122 . The inner concentric circle 121 may have the center 111 of the inner concentric circle 121 , so the center 111 may also be the center of the outer concentric circle 122 .

The display panel 101 may include an image sensor 112 disposed in the sensor area 110, and one pixel unit occupied by a part of the image sensor 112 may be a pinhole (dot) to allow incident light to pass through and then reach The image sensor 112 forms an image. Image sensor 112 may be disposed at least partially in sensor area 110 , or completely disposed in sensor area 110 . The image sensor 112 can form a plurality of dots, and can be used as a spot in the sensor area 110 of the display lower lens device 100 For photographic lenses. Due to the existence of one or more pinholes, one or more sensor pixel units in the sensor area 110 will become one or more invalid sensor pixel units, such as one or more pinholes , because these invalid sensor pixel cells cannot emit light. FIG. 1 illustrates pinholes corresponding to the sensor area 110 in the form of visual point-like areas, corresponding to invalid sensor pixel cells.

The display device 100 has a plurality of pixels or sub-pixels. Different pixels or different sub-pixels in different regions of the display device 100 form different pixel groups. In some embodiments of the invention, the sensor pixel group 113 may be disposed in the sensor area 110 and adjacent to the blurring area 120 . In other words, the sensor pixel group 113 may be disposed at the inner concentric circle 121 , that is, adjacent to the boundary line between the sensor area 110 and the blurred area 120 . The sensor pixel group 113 may include one or more sensor pixel units.

Accordingly, the sensor region 110 including the image sensor 112 may visually exhibit some valid sensor pixels and some invalid sensor pixels. An active sensor pixel may refer to a sensor pixel cell capable of emitting light of any suitable color. An invalid sensor pixel may refer to a sensor pixel cell that does not emit light at all. For example, an invalid sensor pixel may refer to a pixel cell occupied by a pinhole, and the pinhole represented by the image sensor 112 in the sensor area 110 would make the sensor pixel cell originally Function not working. A collection of invalid sensor pixels in sensor area 110 may adversely alter the visually intended appearance of a given image, as shown in FIG. 1 .

One sensor pixel group 113 may include one or more sensor pixel units to form one unit unit. In one embodiment of the present invention, valid sensor pixels and invalid sensor pixels in one sensor area 110 may form a pattern together, or may be regularly arranged. One unit unit, including valid sensor pixels and invalid sensor pixels, to represent the smallest repeating unit on a pattern or arrangement, is represented by one sensor pixel group 113 . For example, the sensor pixel group 113 may include n valid sensor pixels and m invalid sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1. In another embodiment of the present invention, FIG. 4 shows that the sensor pixel group 113 may include four Sensor sub-pixels, so n+m=4, but the invention is not limited to this. For example, sensor pixel group 113 may include sensor sub-pixel 114, sensor sub-pixel 115, sensor sub-pixel 116, and sensor sub-pixel, regardless of the color of the four sensor sub-pixels 117.

The valid sensor pixels in the sensor pixel group 113 may have the maximum sensor pixel luminance value SV. Invalid sensor pixels in the sensor pixel group 113 may have the smallest sensor pixel brightness value of 0. The maximum pixel brightness value may represent a maximum grayscale 255 equal to 100% of the intensity. The minimum pixel luminance value may refer to the minimum grayscale 0 that is equal to 0% of the intensity. The concept of grayscale or intensity is well known in the art, so its details will not be described in detail. In other words, the luminance value of a sensor pixel unit can be SV or 0, so SV can be equal to the luminance value of 100.

In some embodiments of the present invention, the display pixel group 133 may be disposed in the display area 130 and adjacent to the blurring area 120 . In other words, the display pixel group 133 may be disposed at the outer concentric circles 122 , that is, adjacent to the boundary line between the display area 130 and the blurred area 120 . Display pixel group 133 may include one or more display pixel units. FIG. 3 shows that each display pixel group 133 may include a plurality of display sub-pixels, but the present invention is not limited thereto.

Similarly, one display pixel group 133 may include one or more display pixel units to form a unit unit. The number of display pixel units in one unit unit is the same as the number of sensor pixel group units in another unit unit. For example, FIG. 4 illustrates that the display pixel group 133 may include four display sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel group 113 regardless of the color of the sensor sub-pixels. For example, the display pixel group 133 may include a display sub-pixel 134, a display sub-pixel 135, a display sub-pixel 136, and a display sub-pixel 137, but the present invention is not limited thereto.

If the sensor pixel group 113 includes n valid sensor pixels and m invalid sensor pixels, the display pixel luminance value DV of the display pixel unit can be determined, and the following relationship is satisfied: DV=[n/( n+m)]×(maximum pixel luminance value SV). Displays satisfying the aforementioned relationship in the display area 130 Displaying the pixel brightness value DV can ensure visual brightness consistency relative to the sensor area 110 . Therefore, the display pixel brightness value DV may represent a normalized result, or a normalized result.

In some embodiments of the present invention, the blurred pixel group 123 may be arranged in the blurred area 120 . In other words, the blurred pixel group 123 may be disposed between the inner concentric circle 121 and the outer concentric circle 122 , ie, between the sensor area 110 and the display area 130 . A blurred pixel group 123 may include one or more blurred pixel units. FIG. 3 shows that each blurred pixel group 123 may include a plurality of blurred sub-pixels, but the present invention is not limited thereto.

Similarly, one blurred pixel group 123 may include one or more blurred pixel units to form a unit unit. The number of blurring pixel units in one unit unit is the same as the number of sensor pixel units in another unit unit. For example, FIG. 4 shows that the blurred pixel group 123 may include four blurred sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel group 113, but also to the color of the sensor sub-pixels It doesn't matter. For example, one blurring pixel group 123 may include blurring sub-pixels 124, blurring sub-pixels 125, blurring sub-pixels 126, and blurring sub-pixels 127, but the present invention is not limited thereto.

In some embodiments of the invention, there may be a line 102 passing through the sensor pixel group 113 , the blurring pixel group 123 , and the display pixel group 133 . In some embodiments of the present invention, the straight line 102 may further pass through the center 111 of the inner concentric circle 121 , the sensor pixel group 113 , the blurring pixel group 123 , and the display pixel group 133 . 3 shows that along the line 102, the minimum distance between a pixel group 133 and a sensor pixel group 113 is 1, and the minimum distance between a blurring pixel group 123 and a sensor pixel group 113 is Z It is used as a weight, and the minimum distance between one blurring pixel group 123 and one display pixel group 133 is (1-Z), but the present invention is not limited to this. When implementing the method of the present invention, the actual minimum distance between the display pixel group 133 and the sensor pixel group 113 is obtained according to the actual situation at the time of implementation, and can be determined by those skilled in the art, as long as the minimum distance is sufficient for implementation The present invention is sufficient.

Depending on the display pixel luminance value DV and the sensor pixel luminance value SV, eg, the illumination with respect to the luminance of each blurred pixel cell in the blurred area 120 may have a specific blurred pixel luminance value BV. The blurred pixel luminance value BV may represent the gamma level of the blurred pixels in the blurred pixel group 123, but the present invention is not limited thereto. For example, the blurred pixel brightness value BV is not greater than the maximum sensor pixel brightness value SV, and not less than the corresponding display pixel brightness value DV, so as to satisfy the linear weighting relationship according to Z, SV, and DV: BV=(1-Z )×SV+Z×DV, but the present invention is not limited to this.

Thus, a pixel-by-pixel luminance gradient can be formed along the straight line 102 from the sensor pixel group 113 to the display pixel group 133 , so that a given image has a poor visual appearance due to invalid display pixels in the sensor area 110 . , may gradually weaken through the blurring area 120 and converge to the display area 130 . In other words, the luminance gradient of the pixel unit may be used to make the apparent boundary line 11 of the lower lens area 10 appear blurred as shown in FIG. 1, so that the original boundary line 11 may become visually less visible Obvious, or even more rendered virtually invisible.

One blurring pixel group 123 forming one unit is disposed in the blurring area 120 and located between the sensor pixel group 113 and the display pixel group 133 . Each pixel unit in a blurred pixel group 123 has a separate blurred pixel brightness value BV. Each blurred pixel brightness value BV is calculated to align with the corresponding sensor pixel brightness value SV. One unit unit may include n+m sub-pixels regardless of the color of the sub-pixels, and the n+m sub-pixels may be arranged to form a pattern, or to be ordered, for example, by site.

For example, a unit unit in the sensor pixel group 113 may include n valid sensor pixels and m invalid sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1, Therefore, one unit may also correspondingly include n+m blurred pixels located in the blurred pixel group 123 , and may accordingly include n+m display pixels in the display area 130 . A number of blurred pixels in a unit unit that can exclusively correspond to a specific sensor pixel and a specific display image White. For example, the blurred pixel of the first point in one cell unit may correspond to the sensor pixel of the first point in another cell unit along the line 102 and correspond to the first point in the other cell unit The display pixels, and the blurred pixels of the second site in one cell unit may correspond to the sensor pixels of the second site in the other cell unit along the line 102, and correspond to the sensor pixels of the second site in the other cell unit The display pixel of the second site, and so on.

After step 601, an adjusted image 103 with improved, or further optimized, visual presentation quality can then be obtained. FIG. 8 shows an example of an image 103 with updated R/G/B information after the method of the present invention according to FIG. 1 has reduced contour problems. As shown in FIG. 8 , compared to FIG. 1 , the image 103 showing better visual presentation quality can minimize the visual effect of black spots. For example, in the case where the display lower lens area exists, after the method of the present invention is performed on the display panel 101, the occurrence of the image 103 in FIG. see) contour problems on the borderline (substantially invisible) between the display area 130 such as the general area.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
