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

The present invention generally relates to a display device and a method for blurring a boundary line 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 used in the display lens device.

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

To solve such problems, an incomplete sub-pixel layout can be proposed to hide the camera lens under the panel. Also, in the panel, some pixels in the area showing the lower lens are cut off to facilitate the normal function of the photographic lens.

As shown in FIG. 1 , this incomplete sub-pixel layout may cause a contour issue on the boundary line 11 showing the lower lens area 10 and the normal area 20 . FIG. 1 shows that there is a significant visual difference between the displayed lower lens area 10 and the normal area 20, that is, the visual presence of the boundary line 11, so that the presence of the displayed lower lens area 10 will jeopardize the integrity of the panel 1.

In view of the above, the first aspect of the present invention proposes a novel display device, which can improve the visual presentation quality of the display lower lens device under the condition that the lower lens area is displayed, for example, the visual presence of the lower lens area can be minimized. feel. In the case where the lower camera area is visually insensitive, the boundary line will be blurred to hide the lower camera area. The second aspect of the present invention proposes a novel method to blur the boundary line in the display lower lens device, so as to improve the visual presentation quality of the display lower lens device when the display lower lens region exists.

FIG. 2 is an illustration of the flow chart of the method for blurring and displaying the boundary line in the lower lens device of the present invention. 3 to 4 illustrate an example of the operation process for blurring the boundary line in the lower lens device of the present invention.

Please refer to FIG. 2 , step 101 is executed first. Step 101 is a step of inputting a plurality of original pixel units. The original pixel units may be pixels or sub-pixels of a display device.

A pixel can include a plurality of sub-pixels, and each sub-pixel can emit light of a certain color, such as red (referred to as R), green (referred to as G), blue (referred to as G), or another suitable color. color, but the present invention is not limited thereto. In other words, step 101 can also be referred to as inputting R/G/B information.

Please refer to Figure 3. FIG. 3 is a top view showing a lower lens device according to an example of the present invention. Firstly, the display lens device 100 is provided. The lower 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 lower 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 blurred area 120 and the blurred 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 a hollow 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 a center 111 of the inner concentric circle 121 such 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 can be at least partially disposed in the sensor area 110 , or completely disposed in the sensor area 110 . The image sensor 112 can be used to display the camera lens in the lower lens device 100 .

As mentioned above, 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 groups (sets). In some embodiments of the invention, at least one sensor pixel group 113 may be disposed in the sensor region 110 adjacent to the location of the blurring region 120 . In other words, the sensor pixel group 113 may be disposed at the inner concentric circle 121 , ie, the boundary line of the sensor area 110 and the blurring area 120 . 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 invention is not limited thereto.

In some embodiments of the present invention, at least one blurring pixel group 123 may be disposed in the blurring area 120 . In other words, the blurring pixel group 123 may be disposed between the inner concentric circle 121 and the outer concentric circle 122 , that is, may be disposed 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 blurred pixel group 123 may include a plurality of sensor sub-pixels, but the 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 blurring 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 blurring area 120 . The 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 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 blur pixel group 123 , and the display pixel group 133 . In some embodiments of the present invention, the straight line 102 can 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 sense 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 blur pixel group 123 and the sensor pixel group 113 is Z, and the minimum distance between the blurring pixel set 123 and the display pixel set 133 is (1-Z).

FIG. 4 is a partially enlarged view showing the lower lens device 100 along the line 102 of FIG. 3 according to the present invention. The sensor pixel group 113 may include one or more sensor pixel units to form a unit cell. In one embodiment of the present invention, active sensor pixels and inactive sensor pixels in the sensor region 110 may jointly form a pattern, 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 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, ie, n+m=4, but the present invention is not limited thereto. For example, sensor pixel group 113 may include sensor subpixel 114, sensor subpixel 115, sensor subpixel 116, and sensor subpixel 117, but regardless of the color of the four sensor subpixels why.

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

Similarly, the display pixel group 133 may include one or more display pixel units to form a unit unit. The number of blurring pixel units in one cell unit is the same as the number of display pixel units in one cell unit. For example, FIG. 4 shows that the display pixel set 133 may include four display sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel set 113 , regardless of the colors of the four display sub-pixels. For example, one 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.

As described above, the image sensor 112 is disposed in the sensor area 110, and a pixel unit occupied by a part of the image sensor 112 may become a pinhole (represented by a dot) to allow incident The light reaches the image sensor 112 to form a portion of the image. Due to the presence of one or more pinholes (i.e., one or more points represented by the lower display lens area 10 in FIG. One or more sensor pixel units in the sensor region 110 become invalid sensor pixel units. FIG. 1 depicts regions corresponding to sensor regions 110 that are visually dotted, which would correspond to pinholes of inactive sensor pixel units.

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

Because an inactive sensor pixel has no brightness (no illumination available), there may be an unavoidable reduction in sensor pixel set 113 (i.e., a unit unit) of the total brightness. And the more ineffective sensor pixels exist, the smaller the total brightness of the sensor pixel group 113 will be.

To balance the reduction in illumination due to the presence of ineffective sensor pixels, all active sensor pixels in sensor pixel group 113 may have a maximum sensor pixel brightness value SV, while sensor pixel group 113 All invalid sensor pixels in will have a minimum sensor pixel intensity value of 0. The maximum pixel brightness value may represent a maximum grayscale of 255 equal to an intensity of 100%. The minimum pixel brightness value may refer to a minimum gray scale of 0 equal to an intensity of 0%. Since the concept of grayscale or intensity is well known in the art, its details will not be described in detail. In other words, the brightness value of a sensor pixel unit can be SV or 0, so SV can be equal to the brightness value of 100.

Accordingly, the present invention provides the following procedure to mitigate or further eliminate the unwanted visual interference of ineffective sensor pixels in the sensor area 110 . First, as shown in FIG. 2 , step 201 is executed. First determine the display pixel brightness value DV. The display pixel luminance value DV is preferably related to the sensor pixel luminance value SV.

Due to the presence of one or more pinholes, not every sensor pixel unit in sensor area 110 is a valid sensor pixel. On the contrary, the display pixel group 133 is arranged in the display area 130 used as a general display area, so each display pixel unit in the display area 130 can emit any suitable color when the invalid display pixel does not exist. An effective display pixel of light. In some embodiments of the invention, if sensor pixel group 113 includes n valid sensor pixels and m ineffective sensor pixels, then display pixel group 133 may similarly and correspondingly include n+m Active 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 luminance value DV may be proportionally reduced relative to the sensor pixel luminance value SV. The sensor pixel luminance value SV can represent the result of displaying the lower lens.

If the sensor pixel group 113 includes n effective sensor pixels and m ineffective sensor pixels, it can be determined according to the principle of DV = [n/(n+m)]×(maximum pixel brightness value SV) Determine 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 luminance value DV that satisfies the aforementioned relationship can ensure visual consistency of luminance in the display area 130 relative to the sensor area 110 . After the aforementioned steps, for example, the luminance of the display pixel units in the display area 130 can be uniformed and normalized (normalize), so they can share the same display pixel luminance value DV, and have a uniform luminance in the display area 130 brightness. Therefore, the display pixel luminance value DV may represent a normal result or a normalized result.

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

Differently, in order to balance the brightness difference of the pixel units between the sensor area 110 and the display area 130, the illumination, for example, the brightness of each blurred pixel unit in the blurred area 120, can be based on the display pixel brightness value DV and the sensing area DV. The sensor pixel brightness value SV has a specific blurred pixel brightness value BV. For example, the blurred pixel brightness value BV is not greater than the maximum sensor pixel brightness value SV and not smaller than the corresponding display pixel brightness value DV, so as to form a smooth brightness gradient from SV to DV. Therefore, the brightness gradient of the pixel units can be formed along the straight line 102, so that the poor visual presentation of a given image caused by the ineffective sensor pixels in the sensor area 110 can be gradually weakened, and gradually become blurred through the blurring area 120. Converge to display area 130 . In other words, the brightness gradient of the pixel unit can be used to make the display area of the lower lens, such as the obvious boundary line 11 shown in FIG. 1, become blurred, so the original boundary line may become less obvious visually , or further become substantially 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 , for example, 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 brightness 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. 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 be arranged in order, for example, 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 A unit unit may correspondingly include n+m blurred pixels located in one blurred pixel group 123 , or may correspondingly include n+m display pixels located in the display area 130 . A certain blurred pixel in a cell unit may correspond exclusively to a particular sensor pixel and to a particular display pixel. For example, a blurred pixel at a first location in one cell unit may correspond to a sensor pixel at a first location in another cell unit along line 102 and correspond to a first location in another cell unit. Display pixels for the locus. And the blurred pixel of the second position in one unit unit can correspond to the sensor pixel of the second position in the other unit unit along the straight line 102, and corresponds to the second position in the other unit unit. Points are displayed in pixels, 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. Such weighting calculations may involve one or more weights. One or more weights may relate to a dimensional measure such as distance such that the brightness of sub-pixels in the blurred region 120 may be adjusted according to the distance to a reference point, but the invention is not limited thereto.

For example, a specific blurred pixel luminance value BV can be determined according to the weight Z, according to the corresponding sensor pixel luminance value SV, and according to the corresponding display pixel luminance value DV, so as to satisfy a linear weighted calculation: BV = (1-Z)×SV+Z×DV, but the present invention is not limited thereto. The blurred pixel brightness value BV may represent the gamma level of the blurred pixel in the blurred pixel group 123 , but the 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 blur pixel group 123 and a sensor pixel group 113 is Z to be used as In this example, the weight value and the minimum distance between one blurring pixel group 123 and one display pixel group 133 are (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 depending on the situation at the time of implementation, and can be determined by those of ordinary skill in the art, as long as the minimum distance is sufficient It can be used for implementing the present invention. In other words, the present invention introduces weights related to the lower shot to determine the blurred pixel brightness value BV, but the present invention is not limited thereto.

As shown in FIG. 4 , some calculation examples for determining different blurred pixel brightness values BV are proposed below according to some implementations of the present invention. Although the following calculation example relates to the embodiment of n+m=4, the present invention is not limited to the embodiment of n+m=4. Any implementation involving n+m≧2 should be regarded as falling within the scope of the present invention and within the principle of optimization.

first instance

FIG. 4 illustrates a sensor pixel group 113 comprising a first sensor sub-pixel 114, a second sensor sub-pixel 115, a third sensor sub-pixel 116, and a fourth sensor sub-pixel 117, in order to One cell unit 113 is formed regardless of the colors of the four sensor sub-pixels. Four sensor sub-pixels are arranged in a cell unit with respect to their respective specific sites. A location refers to a specific sensor sub-pixel arranged along a given line, and a location in a given unit unit, or to determine a pixel brightness value, such as DV or BV, a place of concern at the time. For example, sensor pixel group 113 including first sensor sub-pixel 114, second sensor sub-pixel 115, third sensor sub-pixel 116, and 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 site of the third sensor sub-pixel 116, and the site of the fourth sensor sub-pixel The position of the pixel 117, but the present invention is not limited thereto. In a 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 an inactive sensor pixel. sensor pixels, so n = 3 and m = 1.

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

[114(100), 115(100), 116(100), 117(0)]

Next, FIG. 4 shows a display pixel group 133 including a first display sub-pixel 134, a second display sub-pixel 135, a third display sub-pixel 136, and a fourth display sub-pixel 137 to form a unit unit 133, and The four display sub-pixels are color independent. The four display sub-pixels are respectively arranged in a unit unit with respect to their specific positions. 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)] x 100 = 75, since the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114;

DV135 = [3/(3+1)] x 100 = 75, since the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115;

DV136 = [3/(3+1)] x 100 = 75, since the third display sub-pixel 136 corresponds in area 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 cell unit is 123, regardless of the color of the four blurred sub-pixels. The four display sub-pixels are respectively arranged in a unit unit with respect to their specific positions. Suppose 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 brightness value BV1 and the second blurred pixel brightness value BV2 may respectively represent a gamma level.

BV124 = (1-0.25) x 100 + 0.25 x 75 = 93.75, since the first blurred sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV = 100);

BV125 = (1-0.25) x 100 + 0.25 x 75 = 93.75, since the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV = 100);

BV126 = (1-0.25) x 100 + 0.25 x 75 = 93.75, since the third blurred sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV = 100);

BV127 = (1-0.25) x 0 + 0.25 x 75 = 18.75, since the fourth blurring sub-pixel 127 corresponds in area to the fourth sensor sub-pixel 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 listed in Figure 5.

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

The four sensor sub-pixels are respectively arranged in a cell unit with respect to their specific positions. While in the second example, the first sensor sub-pixel 114 and the fourth sensor sub-pixel 117 are effective sensor pixels, while the second sensor sub-pixel 115 and the third sensor sub-pixel 116 are Invalid sensor pixels, so n = 2 and m = 2.

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

[114(100), 115(0), 116(0), 117(100)]

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

DV134 = [2/(2+2)] x 100 = 50, since the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114;

DV135 = [2/(2+2)] x 100 = 50, since the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115;

DV136 = [2/(2+2)] x 100 = 50, since the third display sub-pixel 136 corresponds in area to the third sensor sub-pixel 116;

DV137 = [2/(2+2)]×100=50, 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(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 cell unit is 123, regardless of the color of the four blurred sub-pixels. The four blurred sub-pixels are respectively arranged in a unit unit with respect to their specific positions. Assuming Z = 0.50, this means that blurring pixel set 123 is located equidistant between sensor pixel set 113 and display pixel set 133 . Then, according to BV = (1-Z) × SV + Z × DV, the blurred pixel brightness value BV of each blurred sub-pixel is determined.

BV124 = (1-0.50) x 100 + 0.50 x 50 = 75, since the first blurring sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV = 100);

BV125 = (1-0.50) x 0 + 0.50 x 50 = 25, since the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV = 0);

BV126 = (1-0.50) x 0 + 0.50 x 50 = 25, since the third blurred sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV = 0);

BV127 = (1-0.50) x 100 + 0.50 x 50 = 75, since the fourth blurring sub-pixel 127 corresponds in area to the fourth sensor sub-pixel 117 (SV = 100).

The above adjustment results can be simplified as:

[124(75), 125(25), 126(25), 127(75)]

The calculation results are listed in Figure 6.

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

third example

FIG. 4 illustrates a sensor pixel group 113 comprising a first sensor sub-pixel 114, a second sensor sub-pixel 115, a third sensor sub-pixel 116, and a fourth sensor sub-pixel 117, in order to One cell unit 113 is formed regardless of the colors of the four sensor sub-pixels. The four sensor sub-pixels are respectively arranged in a cell unit with respect to their specific positions. 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, while the fourth sensor sub-pixel 117 is an effective 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 respectively have the minimum sensor pixel brightness value of 0, while the fourth sensor sub-pixel Sensor subpixel 117 has a maximum sensor pixel brightness value SV (brightness 100). The aforementioned initial conditions can be simplified to [subpixel (corresponding brightness value)]:

[114(0), 115(0), 116(0), 117(100)]

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

DV134 = [1/(3+1)] x 100 = 25, since the first display sub-pixel 134 corresponds in area to the first sensor sub-pixel 114;

DV135 = [1/(3+1)] x 100 = 25, since the second display sub-pixel 135 corresponds in area to the second sensor sub-pixel 115;

DV136 = [1/(3+1)] x 100 = 25, since the third display sub-pixel 136 corresponds in area to the third sensor sub-pixel 116;

DV137 = [1/(3+1)]×100=25, since the fourth display sub-pixel 137 corresponds in area to the fourth sensor sub-pixel 117 .

The above result can be simplified as:

[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 cell unit is 123, regardless of the color of the four blurred sub-pixels. The four blurred sub-pixels are respectively arranged in a unit unit with respect to their specific positions. Suppose 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 Optimize the pixel brightness value BV.

BV124 = (1-0.75) x 0 + 0.75 x 25 = 18.75, since the first blurred sub-pixel 124 corresponds in area to the first sensor sub-pixel 114 (SV = 0);

BV125 = (1-0.75) x 0 + 0.75 x 25 = 18.75, since the second blurring sub-pixel 125 corresponds in area to the second sensor sub-pixel 115 (SV = 0);

BV126 = (1-0.75) x 0 + 0.75 x 25 = 18.75, since the third blurred sub-pixel 126 corresponds in area to the third sensor sub-pixel 116 (SV = 0);

BV127 = (1-0.75) x 100 + 0.75 x 25 = 43.75, since the fourth blurring sub-pixel 127 corresponds in area to the sensor sub-pixel 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 brightness in each cell unit 113/123/133 is the same (100), this results in a uniform visual brightness quality across different groups of pixels.

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 to obtain a weighted result of each pixel unit in the blurred area 120 . The newly obtained weighted result of the pixel units in the blurring area 120 can represent the gradient used to soften the outline, so as to blur the obvious boundary line of the lower shot area shown in FIG. 1 . For example, in a first example, the brightness of some 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(93.75), 125(93.75), 126(93.75 ), 127(18.75)]. In a second instance, the brightness of some 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 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(18.75), 125(18.75), 126(18.75) , 127 (43.75)].

The weighted result of the pixel unit group is a set of each weighted result corresponding to each pixel unit in the blurred 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 instance is [124(18.75), 125(18.75), 126(18.75), 127(43.75)]. Each pixel unit located in the blurred area 120 with a weighted result on brightness becomes an adjusted pixel unit corresponding to the related pixel unit in a different area. For example, in the first instance [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 subpixel (display lower lens) 115 and with the normal first display subpixel 135, form the adjusted The passed first blurred sub-pixel 125. In the third example, [117(100)-127(43.75)-137(25)] together with the first sensor subpixel (display lower lens) 117 and with the normal first display subpixel 137, form the adjusted The passed first blurred sub-pixel 127. The results of the improved brightness gradient are shown in the first example, the second example, or the third example, respectively.

After the aforementioned 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. The R/G/B information can include different information types in terms of brightness, but not its respective color information. For example, the R/G/B information in the sensor area 110 may relate to the raw display results of the lower shot, such as the maximum pixel intensity value SV or the minimum pixel intensity value 0. The R/G/B information in the display area 130 can refer 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 blurred area 120 may involve a set of multiple gradient results, for example, a set of blurred pixel brightness values BV obtained according to BV = (1-Z) × SV + Z × DV . Z is a variable corresponding to the location 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 weighted results become in the blurred area 120 In 120, the set of luminance information associated with all pixel units is used to output a plurality of adjusted pixel units for display purposes.

After the above-mentioned adjustment method, a novel display device 100 is provided to optimize the visual presentation quality of the lower lens device under the condition that the lower lens area is displayed, for example, it can minimize the visual presence of the lower lens area. . FIG. 3 is a top view showing a lower lens device according to an example of the present invention. FIG. 4 is a partially enlarged view showing the lower lens device along a straight line according to FIG. 3 . 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 under a display panel. The display lower lens device may include a display panel 101 for displaying pictures or images (eg image 103 ). The lower 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 blurred area 120 and the blurred 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 a hollow 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 become a pinhole (dot) to allow incident light to pass through and reach The image sensor 112 forms an image. The image sensor 112 may be at least partially disposed in the sensor area 110 , or completely disposed in the sensor area 110 . The image sensor 112 can form a plurality of dots, and can be used to display a photographic lens in the sensor area 110 of the lower lens device 100 . Due to the existence of one or more pinholes, one or more sensor pixel units in the sensor region 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 sensor area 110 in the form of visual point-like regions corresponding to inactive sensor pixel units.

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 form different pixel groups. In some embodiments of the invention, sensor pixel group 113 may be disposed in sensor area 110 and adjacent blurring area 120 . In other words, the sensor pixel group 113 may be disposed at the inner concentric circle 121 , ie, adjacent to the boundary line between the sensor area 110 and the blurring area 120 . The sensor pixel group 113 may include one or more sensor pixel units.

Therefore, the sensor area 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 unit capable of emitting light of any suitable color. A dead 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 that is occupied by a pinhole, and the pinhole, represented by image sensor 112 in sensor area 110, would render the sensor pixel cell otherwise Function is invalid. The collection of ineffective sensor pixels in the 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 a unit unit. In one embodiment of the present invention, the valid sensor pixels and the invalid sensor pixels in one sensor area 110 may jointly form a pattern, or may be regularly arranged. One unit unit including valid sensor pixels and invalid sensor pixels to represent the minimum 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 present invention is not limited thereto. For example, regardless of the color of the four sensor subpixels, sensor pixel group 113 may include sensor subpixel 114, sensor subpixel 115, sensor subpixel 116, and sensor subpixel 117.

An active sensor pixel in sensor pixel group 113 may have a maximum sensor pixel luminance value SV. Inactive sensor pixels in sensor pixel group 113 may have a minimum sensor pixel brightness value of zero. A maximum pixel brightness value may represent a maximum gray scale of 255 equal to an intensity of 100%. The minimum pixel brightness value may refer to a minimum gray scale of 0 equal to an intensity of 0%. The concept of gray scale or intensity is well known in the art, so its details will not be described in detail. In other words, the brightness value of a sensor pixel unit can be SV or 0, so SV can be equal to the brightness 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 circle 122 , ie, adjacent to the boundary line between the display area 130 and the blurring area 120 . The 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 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 shows that the display pixel set 133 may include four display sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel set 113 , regardless of the color of the sensor sub-pixels. For example, the display pixel group 133 may include the display sub-pixel 134, the display sub-pixel 135, the display sub-pixel 136, and the display sub-pixel 137, but the present invention is not limited thereto.

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

In some embodiments of the present invention, the blurring pixel group 123 may be disposed in the blurring area 120 . In other words, the blurring 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 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 blurred pixel units in one unit unit is the same as the number of sensor pixel units in the other 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 with the color of the sensor sub-pixels irrelevant. For example, one blurring pixel group 123 may include blurring sub-pixels 124, 125, 126, and 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 set 113 , the blur pixel set 123 , and the display pixel set 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 blur pixel group 123 and a sensor pixel group 113 is Z And the minimum distance used as the weight and 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 depending on the situation at the time of implementation, and can be determined by those of ordinary skill in the art, as long as the minimum distance is sufficient It can be used for implementing the present invention.

Depending on the display pixel luminance value DV and the sensor pixel luminance value SV, for example the illumination with respect to the luminance of each blurred pixel unit in the blurred region 120 may have a specific blurred pixel luminance value BV. The blurred pixel brightness value BV may represent the gamma level of the blurred pixel 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 is not smaller 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 thereto.

Thus, along the straight line 102 from the sensor pixel group 113 to the display pixel group 133, a pixel-by-pixel brightness gradient can be formed such that a given image has poor visual presentation due to ineffective display pixels in the sensor area 110. , can gradually weaken through the blurring region 120 and converge to the display region 130 . In other words, the brightness gradient of the pixel unit can be used to make the obvious boundary line 11 showing the lower lens area 10 as shown in FIG. 1 look blurred, so that the original boundary line 11 may become less visible become apparent, or become more substantially invisible.

One blurred pixel group 123 forming a unit unit is disposed in the blurred area 120 and is located between the sensor pixel group 113 and the display pixel group 133 . Each pixel unit in a blurred pixel group 123 has an individual blurred pixel brightness value BV. Each blurred pixel luminance value BV is calculated to align with the corresponding sensor pixel luminance 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 be arranged in order, for example, according to positions.

For example, one 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, a unit unit may also correspondingly include n+m blurred pixels located in the blurred pixel group 123 , and may correspondingly include n+m display pixels in the display area 130 . Some blurred pixels in a cell unit may correspond exclusively to specific sensor pixels and specific display pixels. For example, a blurred pixel of a first location in one cell unit may correspond to a sensor pixel of a first location in another cell unit along line 102 and correspond to a first location in another cell unit , and the blurred pixel at the second location in one unit unit may correspond to the sensor pixel at the second location in the other unit unit along the line 102, and correspond to the sensor pixel at the second location in the other unit unit The display pixel of the second position, and so on.

After step 601 , the 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 according to FIG. 1 after undergoing the method of the present invention with reduced contouring problems. As shown in FIG. 8 , compared to FIG. 1 , the image 103 exhibits a better visual presentation quality that minimizes the visual effect of black dots. For example, in the case where the display lower lens area exists, after the method of the present invention is executed on the display panel 101, the image 103 in FIG. See) the outline problem on the boundary line (substantially invisible) between the display area 130 such as the general area.
