Description

monitor

The present invention relates to a display, and more particularly to a display having curved edges.

Due to the increasing functionality and smaller size of electronic products, displays for displaying images may also be designed in various shapes to meet the needs of electronic products. For example, when the display is applied to a smart watch, the display may be The display panel is designed to be round to meet the habits of the average consumer. However, in the prior art, the pixels in the display panel are often designed as squares to reduce the complexity and cost of fabrication.

FIG. 1 is a schematic diagram of a display panel 100 of the prior art. The display panel 100 includes a plurality of pixels 110. Since each of the pixels 110 is square, even if the pixels 110 in the display panel 100 are arranged in a circular shape, they are still jagged at the edge of the display panel 100 and cannot be flat curved (as shown in FIG. 1). In the case where the partial pixels 110 are arranged in a circular shape, the edges indicated by the thick lines are jagged, and such zigzag defects are more apparent on the display panel having a lower pixel density.

On the other hand, in order to make the display panel have a smoother curved shape, the prior art also uses the curved frame 120 to cover the display panel 100. Therefore, the display panel 100 can be a square display panel, and the appearance thereof can still be The display is a smooth circular display panel. However, the area covered by the frame 120 on the edge of the display panel 100 cannot be used to display images, which not only makes the display panel 100 unable to display a complete image, but also causes waste of backlight power. . Therefore, how to make the display panel have a smooth curved shape and can efficiently display an image becomes a problem to be solved.

One embodiment of the present invention provides a display. The display includes a frame and a display surface board. The frame covers the periphery of the display panel, and the display panel includes a first pixel, a second pixel, and a third pixel. The first pixel includes three sub-pixels of different colors, the second pixel includes three sub-pixels of different colors, and one of the second pixels is a vertex angle of one corner of the first pixel. The third pixel is disposed in a region sandwiched by the border, the first pixel, and the second pixel. The side of the third pixel adjacent to the border has an arc edge, and the third pixel contains only one sub-pixel, and the sub-pixel of the third pixel may be adjacent to one sub-pixel or two sub-pixels of the first pixel. And one of the third pixels is adjacent to one of the second pixels. Since the side of the third pixel adjacent to the border also has an arc edge, it is not necessary to arrange the arc in a square pixel, and the third pixel can only contain one sub-pixel to present an image, and can be adjacent to The sub-pixels of different colors are combined to form a full-color pixel, and the visual effect similar to the complete pixel is achieved. Therefore, the display of the embodiment of the invention can have a smooth curved shape and can be efficiently compared with the prior art display panel. Present the image.

Another embodiment of the present invention provides a display. The display includes a frame and a display surface board. The frame covers the periphery of the display panel, and the display panel includes a first pixel, a second pixel, and a third pixel. The first pixel includes three sub-pixels of different colors, the second pixel includes three sub-pixels of different colors, and one of the second pixels is a vertex angle of one corner of the first pixel. The third pixel is disposed in a region sandwiched by the border, the first pixel, and the second pixel. The side of the third pixel adjacent to the border has an arc edge, and the third pixel includes at least one sub-pixel. The illuminating region of the at least one sub-pixel of the third pixel is adjacent to the illuminating region of one of the first pixels, and the illuminating region of the third pixel and the sub-pixel of the second pixel Adjacent. The actual brightness of at least one sub-pixel of the third pixel is proportional to the original brightness of at least one sub-pixel of the third pixel, and inversely proportional to the effective area ratio of at least one sub-pixel of the third pixel. The effective area ratio is the ratio of the actual area of the subpixel of the third pixel to the standard area. Since the side of the third pixel adjacent to the frame also has an arc edge, and the square pixels are not arranged in an arc shape, and the light-emitting area of the third pixel of the third pixel can be used to present an image, the present invention is implemented. The display of the example can have a smooth curved shape. In addition, the actual area of at least one sub-pixel of the third pixel may be compared with the standard by having an arc edge The quasi-area is small, so the actual brightness of at least one sub-pixel in the third pixel compensates for the difference from the sub-pixels of other pixels according to the effective area ratio, and can be presented more efficiently than the display panel of the prior art. image.

Another embodiment of the present invention provides a display. The display includes a border and a display surface Board and control unit. The border covers the perimeter of the display panel. The display panel includes a first sub-pixel and a second sub-pixel. The visible area of the second sub-pixel is smaller than the visible area of the first pixel. The control unit is electrically coupled to the first sub-pixel and the second sub-pixel, and is configured to respectively control the first grayscale value and the second grayscale value respectively indicated by the received first signal and the second signal The brightness of the subpixel and the second subpixel. When the first grayscale value is the same as the second grayscale value, the control unit controls the brightness of the second subpixel to be greater than the brightness of the first subpixel. The display of the embodiment of the present invention can have a smooth curved shape, and the control unit can control the actual brightness according to the difference between the visible areas of the first sub-pixel and the second sub-pixel. Therefore, the image can be presented more efficiently than the display panel of the prior art.

2 is a schematic diagram of a display 200 in accordance with an embodiment of the present invention. The display 200 includes a display panel 210 and a bezel 220. The bezel 220 covers the periphery of the display panel 220. FIG. 3 is a partial enlarged view of the display panel 200. In FIG. 3, display panel 210 can include pixels 212A, 212B, and 212C. The pixel 212A contains three different color sub-pixels 212A ₁ , 212A ₂ and 212A ₃ . In an embodiment of the invention, the sub-pixels 212A ₁ , 212A _{2 ,} and 212A ₃ may be sub-pixels of red, green, and blue, respectively. However, the present invention is not limited thereto. In other embodiments of the present invention, the sub-pixels 212A ₁ , 212A _{2 ,} and 212A ₃ may also be sub-pixels of other colors. The pixel 212B includes three different color sub-pixels 212B ₁ , 212B ₂ and 212B ₃ , and the angle θ _{B of the} pixel 212B may be the opposite angle of the angle θ _A of the first pixel 212A. The pixel 212C can be disposed in a region sandwiched by the frame 220, the pixel 212A, and the pixel 212B, and the side adjacent to the frame 220 of the pixel 212C has an arc edge. The pixel 212C may include only one sub-pixel 212C _x .

In the display panel 210 of an embodiment of the present invention, each sub-pixel of each pixel can be The light-emitting area and the driving circuit are included, and the light-emitting area of each sub-pixel can be used to emit color light to present an image, and the driving circuit of each sub-pixel can drive the light-emitting area of the sub-pixel according to the received gray level data. In order to prevent the user from observing the driving circuit and affecting the quality of the image displayed by the display panel 210, the light emitting area of each sub-pixel may be disposed above the corresponding driving circuit. Since the second and third views present the display panel 210 in a plan view, the user only sees the light-emitting area of each sub-pixel without seeing the driving circuit of each sub-pixel, that is, the display panel 210. The illuminating area of the pixel is the illuminating area including the pixels of each sub-pixel, that is, the visible area of the display panel 210.

In an embodiment of the present invention, since the pixel 212C is located at the edge of the display panel 210, and the pixel 212C is only adjacent to the sub-pixel 212A _{3 of the} pixel 212A and the sub-pixel 212B _{1 of the} pixel 212B, the pixel is represented by the pixel. 212C is small and insufficient for sub-pixel comprises three different colors of light emitting region presentation image, so the pixel 212C 212C may comprise only a sub-pixel _X, in the display panel 210, i.e., the sub-pixel pixel 212C 212C _x may be adjacent to the sub-pixel 212A _{3 of the} pixel 212A and adjacent to the sub-pixel 212B _{1 of the} pixel 212B.

In an embodiment of the present invention, in order to make the image at the edge of the display panel 210 smoother, the color of the sub-pixel 212C _x of the pixel 212C may be the same as the color of the sub-pixel 212A ₃ located at the angle θ _A of the pixel 212A and The color of the sub-pixel 212B ₁ located at the angle θ _B of the pixel 212B is different. For example, the sub-pixel 212A ₃ is a blue sub-pixel, and the sub-pixel 212B ₁ is a red sub-pixel, so the sub-pixel 212C _x can be a green sub-pixel. In this way, the sub-pixel 212C _x can be matched with the sub-pixels 212A ₃ and 212B _{1 of the} adjacent pixels, and the visual effect of a full-color pixel can be achieved.

In one embodiment of the invention, the brightness of the sub-pixel 212C _x of the pixel 212C may be between the brightness of the pixel 212A and the brightness of the pixel 212B. For example, if the received gray level value of brightness according to the calculated sub-pixel of the pixel 212A 212A _1, 212A _2, 212A ₃ is B _A, and the pixels of the sub-pixel 212B 212B _1, 212B _2, 212B ₃ The brightness calculated by the received grayscale value is B _B , and the brightness of the gray scale value of the subpixel 212C _x can be set between B _A and B _B to make the pixels 212A, 212B and 212C The rendered image is smoother.

4A is a schematic diagram of the pixels 212B and 212G of the display panel 210, and FIG. 4B is a side view of the sub-pixels of the pixels 212B and 212G of the display panel 210, which can be more specifically illustrated by the 4A and 4B drawings. The construction of each pixel. In FIG. 4A, the sub-pixel 212B _{1 of the} pixel 212B includes the light-emitting area L212B ₁ and the driving circuit D212B ₁ , and the sub-pixel 212B _{2 of the} pixel 212B includes the light-emitting area L212B ₂ and the driving circuit D212B ₂ , and the sub-picture of the pixel 212B The element 212B ₃ includes a light-emitting area L212B ₃ and a driving circuit D212B ₃ . Sub-pixel 212B _1, 212B ₂ and the drive circuit 212B ₃ of D212B _1, D212B ₂ and D212B ₃ according to the gray scale data of the received sub-pixels are driven 212B _1, 212B ₂ and the light emitting region 212B ₃ of L212B _1, L212B ₂ and L212B ₃ emit different colors of light. Similarly, the sub-pixel 212G _{1 of the} pixel 212G includes the light-emitting area L212G ₁ and the driving circuit D212G ₁ , and the sub-pixel 212G _{2 of the} pixel 212G includes the light-emitting area L212G ₂ and the driving circuit D212G ₂ , and the sub-pixel 212G _{3 of the} pixel 212G The light emitting area L212G ₃ and the driving circuit D212G _{3 are included} . Since the display panel 210 emits images by emitting different color lights through the light-emitting areas of the sub-pixels of the respective pixels, in the 4A, the sub-pixels 212B ₁ , 212B ₂ , 212B ₃ , 212G ₁ , 212G _{2 ,} and 212G ₃ The light emitting regions L212B ₁ , L212B ₂ , L212B ₃ , L212G ₁ , L212G _{2 ,} and L212G ₃ may be respectively disposed in the driving circuit D212B _{1 of} each of the sub pixels 212B ₁ , 212B ₂ , 212B ₃ , 212G ₁ , 212G _{2 ,} and 212G ₃ . Above D212B ₂ , D212B ₃ , D212G ₁ , D212G ₂ and D212G ₃ , when the user views the display panel 210 , only the light-emitting area of each sub-pixel is seen without seeing each sub-pixel. The driving circuit, that is, the light-emitting area of each sub-pixel in the display panel 210 is the visible area of the display panel 210. It is claimed that each sub-pixel in the display panel 210 can include a light-emitting area and a driving circuit, and the light-emitting area can be disposed above the driving circuit thereof. In the second figure, the display panel 210 is each The illuminating region of a sub-pixel represents its sub-pixel to present the relative positional relationship between each sub-pixel.

In an embodiment of the present invention, the areas of the light-emitting areas L212G ₁ , L212G _{2 ,} and L212G ₃ of the sub-pixels 212G ₁ , 212G _{2 ,} and 212G ₃ of the pixels 210G that are not located at the edge of the display panel 210 can be combined with the driving circuit D212G _{1 .} The areas of D212G ₂ and D212G ₃ are the same or substantially the same, but the invention is not limited thereto. In an embodiment of the present invention, since the driving circuits D212B ₁ , D212B ₂ and D212B _{3 of the} sub-pixels 212B ₁ , 212B ₂ and 212B ₃ are covered by the frame 220, the sub-pixels 212B ₁ , 212B ₂ and 212B emitting region ₃ L212B _1, L212B ₂ and L212B ₃ lines were provided at the sub-pixel on the border is not covered by the driving circuit 220. That is, the side adjacent to the frame 220 of the sub-pixels 212B ₁ , 212B _{2 ,} and 212B ₃ has the same arc edge as the frame 220 , and the edge of the light-emitting areas L212B ₁ , L212B _{2 ,} and L212B _{3 is} the edge of the frame 220 . Extending along the arc. Therefore, the areas of the light-emitting areas L212B ₁ , L212B _{2 ,} and L212B ₃ of the sub-pixels 212B ₁ , 212B ₂ , and 212B _{3 are different} from the areas of the drive circuits D212B ₁ , D212B _{2 ,} and D212B ₃ .

The first picture shows 4B show side sectional view showing a pixel 210 of the panel sub-pixels 212G and 212B in FIG. 4B, the light-emitting sub-pixel region _{212B. 1} L212B ₁ may comprise the OLED OLED _212B1, and sub-picture The light-emitting region L212G _{1 of the} element 212G ₁ may include an organic light-emitting diode OLED _212G1 . Sub-pixel region 212B ₁ is driven D212B ₁ may comprise for driving the OLED OLED _212B1 of a thin film transistor TFT _212B1, and the sub-pixel region 212G ₁ is driven D212G ₁ may comprise for driving the OLED _OLED 212G1 thin film transistor TFT _212G1.

Since the light-emitting region L212B ₁ emits color light by the organic light-emitting diode OLED _212B1 , and the light-emitting region L212G ₁ emits color light by the organic light-emitting diode OLED _212G1 , the organic light-emitting diode OLED _212B1 and the OLED can be adjusted. The position of _212G1 is used to set the positions of the light-emitting areas L212B ₁ and L212G ₁ . In other words, each sub-pixel can adjust the position of the organic light-emitting diode as the position of its light-emitting area according to its position on the display panel 210. For example, since the light-emitting area L212B ₁ is located at the edge of the display panel 210 and adjacent to the arc edge of the frame 220, and the light-emitting area L212G ₁ is not adjacent to the arc edge of the frame 220, the light-emitting area L212B _{1 is} adjacent to the frame 220. one side can be relatively retracted, in order to avoid wasting unnecessary power consumption of the light emitting frame 220 are covered; opposite to the light-emitting region is not necessary retracted L212G _1, the light-emitting area will L212B ₁ than the light emitting region smaller L212G ₁ .

In addition, since the driving circuit D212G _{1 of the} sub-pixel 212G ₁ can be disposed under the light-emitting area L212G ₁ , and the light-emitting area L212G ₁ does not have to be retracted due to being adjacent to the arc edge of the frame 220 , the driving circuit D212G ₁ area may be the same light emitting region area L212G _1. The driving circuit D212B _{1 of the} sub-pixel 212B ₁ may also be disposed under the light-emitting area L212B ₁ . Although the light-emitting area L212B ₁ has a small area to avoid being covered by the frame 220, since the driving circuit is not used to directly emit color light and is not covered by the frame 220, the driving circuit D212B ₁ can be disposed on the frame. below 220 without retracted, i.e., _a driving circuit D212B frame 220 may be covered, but the upper part of the driving circuit is covered not have _a light emitting region D212B L212B _1, so the driving circuit D212B emitting area may be greater than ₁ Area of zone L212B ₁ . In addition, the driving circuit may be the same D212B area _of the area of the driving circuit D212G _1, so that the panel 210 may still be used for producing a conventional square pixel display process to produce sub-pixel driving circuit D212B 212B _{1 1.}

Although in the display panel 210, since the pixel 212C is adjacent only to the sub-pixel 212A _{3 of the} pixel 212A and the sub-pixel 212B _{1 of the} pixel 212B, it can be determined that the pixel 212C is insufficient to contain the three sub-pixels, but the present invention It is not limited to this criterion. For example, in FIG. 3, the pixel 212D of the display panel 210 is adjacent to both the sub-pixels 212E ₂ and 212E _{3 of the} pixel 212E, and the pixel 212D of the display panel 210 is adjacent to the sub-pixel 212F _{1 of the} pixel 212F. , in which the illuminating area of the pixel 212D for presenting the image is still small enough to contain three different colors of sub-pixels, so in one embodiment of the present invention, the pixel 212D may only include the sub-pixel 212D _x , That is, in the display panel 210, the sub-pixel 212D _{x of the} pixel 212D may be adjacent to the sub-pixels 212E ₂ and 212E _{3 of the} pixel 212E, and the sub-pixel 212D _{x of the} pixel 212D may be the sub-pixel 212F _{1 of the} pixel 212F. Adjacent. The color of the sub-pixel 212D _x of the pixel 212D may be different from the color of the adjacent sub-pixel 212F _{1 and} the color of the sub-pixel 212E ₃ . For example, the sub-pixel 212F ₁ is a red sub-pixel, and the sub-pixel 212E ₃ is a red sub-pixel, so the sub-pixel 212D _x can be a green sub-pixel. In this way, the sub-pixel 212D _x can also be matched with the sub-pixels 212F ₁ and 212E _{3 of the} adjacent pixels, and the visual effect of a full-color pixel can be achieved.

Although the pixels 212C and 212D located at the edge of the display panel 210 contain only one sub-pixel, the present invention is not limited thereto. In the display panel 210 of FIG. 3, the pixels 212A are also disposed in the area sandwiched by the frame 220, the pixels 212G, and the pixels 212F. The angle θ _G of the pixel 212G is the apex angle of the angle θ _F of the pixel 212F. The side of the pixel 212A adjacent to the bezel 220 has an arc edge.

The pixel 212A may be adjacent to the three light-emitting regions of the three sub-pixels 212F ₁ , 212F ₂ , and 212F ₃ of the pixel 212F, and the pixel 212A may be adjacent to the light-emitting region of the sub-pixel 212G ₁ of the pixel 212G. In other words, although the pixel 212A is located at the edge of the display panel 210 and also has an arc edge, its light-emitting area is large, but still enough to contain three different color sub-pixels 212A ₁ , 212A ₂ , 212A ₃ . That is, the three sub-pixels 212A ₁ , 212A ₂ , and 212A _{3 of the} pixel 212A may be adjacent to the three sub-pixels 212F ₁ , 212F ₂ , and 212F _{3 of the} pixel 212F, respectively, and the pixel 212A only passes through the sub-pixel. 212A _{3 is} adjacent to the sub-pixel 212G _{1 of the} pixel 212G.

By adjusting the light-emitting area of each sub-pixel, the display panel 210 can have a smooth arc edge, and the sub-pixels included in each pixel can be determined according to the size of each pixel, for example, the arc-side but the light-emitting area is compared. A large pixel such as 212A may contain sub-pixels of three colors, while a pixel located at the arc edge but having a smaller illuminating area such as 212C may have only a single color sub-pixel 212C _x and may be based on sub-pixel 212C _x the adjacent sub-pixel color and 212B ₁ to 212A ₃ to determine the color sub-pixel 212C _x such that the sub-pixel 212C _x sub-pixel adjacent to the pixel of 212A ₃ 212B ₁ and with each other, can be achieved A visual effect similar to a complete pixel. As a result, the display 200 can have a smooth arc edge and can render images more efficiently than prior art display panels.

Although the display panel 210 can simultaneously make the pixel 212A have three according to the above judgment criteria. The color sub-pixels are such that the pixels 212C and 212D have only a single color sub-pixel. However, the present invention is not limited thereto. In other embodiments of the present invention, the display panel 210 may also only define a picture. The prime 212A has sub-pixels of three colors, and the pixels 212C and 212D have other numbers or colors of sub-pixels, or the display panel 210 can only limit the pixels 212C and 212D to have only a single color. The sub-pixels, and the pixels 212A also have sub-pixels of a single color, are all within the scope of the present invention.

Since the illuminating area of the sub-pixel having the arc edge is smaller than the illuminating area of the sub-pixel located at the center of the display panel 210, in an embodiment of the present invention, the display 200 may further include a processing unit, when the processing unit receives the inclusion When the first signal of the gray scale data is displayed, the processing unit can control the driving circuit of the sub-pixel according to the first signal, and can adjust the actual brightness finally displayed on the display 200 according to the area of the light-emitting area of the sub-pixel. The actual brightness can be different from the original brightness represented only by the grayscale data. For example, each sub-pixel of the pixel 212A 212A _1, 212A _{2, 212A. 3} may be the actual brightness of each pixel of sub-pixels 212A 212A _1, 212A _{2, 212A. 3} is proportional to the original luminance, and each sub-pixel of the pixel 212A 212A _1, 212A _{2, 212A. 3} may be the actual brightness of each pixel of sub-pixels 212A 212A _1, 212A _{2, 212A. 3} the effective area is inversely proportional to the ratio of the sub-pixel 212A The effective area ratio of ₁ may be the ratio of the actual area to the standard area of the sub-pixel 212A ₁ . In an embodiment of the present invention, the actual luminance B' _{A1 of the} sub-pixel 212A ₁ may be as shown in Equation 1: B' _A1 = B _A1 × (S ₀ / S _A1 )

B _A1 may be the original brightness of the sub-pixel 212A ₁ , S _A1 may be the actual area of the sub-pixel 212A ₁ , and S ₀ may be the standard area of the sub-pixel 212A ₁ (eg, located in the center of the panel, not affected by the periphery) Pixel size). In the standard area in one embodiment of the invention, the actual area 212A ₁ sub-pixel may be a sub-pixel area of the light-emitting region 212A ₁ L212A _1, while sub-pixel 212A ₁ can display panel 210 is not located on the edge The area of the light-emitting area of the sub-pixel, for example, the area of the light-emitting area L212G ₁ of the sub-pixel 212G ₁ .

As a result, since the sub-pixel 212A ₁ is located at the edge of the display panel 210 and has an arc edge, the light-emitting area L212A _{1 of the} sub-pixel 212A ₁ is smaller than the light-emitting area of the sub-pixel 212G _{1 located} at the center of the display panel 210. The area L212G ₁ , so if the image is directly presented according to the original brightness of the neutron pixel 212A ₁ of the picture data source, it may be because the area of the light-emitting area L212A ₁ of the sub-pixel 212A ₁ is small, resulting in an image that is more expected than expected. the darker, so sub-pixel 200 may display the actual luminance B 212A ₁ 'of the effective area _{A1 of} the sub-pixel _{212A. 1} ratio S _A1 / S ₀ is inversely proportional way, to avoid sub-pixel 212A ₁ because of the smaller area of light emitting region L212A ₁ caused the problem of insufficient brightness. For example, if the original picture source lines represent luminance pixel to be rendered in the grayscale values, and the original picture Source neutron pixel gray scale value of 20 212A _1, since the sub-pixels of the actual 212A ₁ The area S _{A1 is} only half of the standard area S ₀ , so the gray scale value of the sub-pixel 212A ₁ can be adjusted to 40 so that the actual brightness B′ _{A1 of} the sub-pixel 212A ₁ can still meet the needs of the image frame, but the present invention Not limited to this.

Figure 5 is a schematic illustration of a display 500 in accordance with one embodiment of the present invention. The display 500 includes a display panel 210, a bezel 220, and a controller 530. The control unit 530 can be electrically coupled to each sub-pixel in the display panel 210, so the control unit 230 can be used to receive the data of the image frame, and can be controlled according to the grayscale value of each sub-pixel in the data of the image frame. The brightness of each sub-pixel. For example, after the computer or the processor generates the picture data, the control unit 530 can receive the signal transmitted by the computer or the processor and control the brightness of the pixel according to the gray scale value indicated by the received signal.

In an embodiment of the present invention, when the control unit 530 receives the first signal corresponding to the sub-pixel 212A _{1 and} the second signal corresponding to the sub-pixel 212G ₁ , the control unit 530 can display the sub-picture according to the first signal. The gray scale value of the prime 212A ₁ causes the pixel 212A _{1 to} emit a color light corresponding to the brightness, and the pixel 212G ₁ emits a color light corresponding to the brightness according to the gray scale value of the subpixel 212G ₁ indicated by the second signal, so that the display panel 210 can present a complete image. The illuminating area of the sub-pixel 212A ₁ is smaller than the illuminating area of the sub-pixel 212G ₁ . Therefore, if the gray level value corresponding to the first signal is the same as the gray level value corresponding to the second signal, the control unit 530 according to the effective area ratio of sub-pixels 212A _1, the actual luminance of the sub-pixel 212A ₁ greater than the actual luminance of the sub-pixel 212G _1. Luminance detail, the control unit 230 may be based on the effective area ratio of sub-pixels 212A ₁ of the visible region 212A ₁ sub-pixel unit area is larger than the sub-pixel 212G ₁ visible region per unit area. To compensate for the reduced brightness because the pixel design is small or because the pixels are obscured by the border 220. Specifically, the control unit 530 (for example, the timing controller) can adjust the signal for driving the pixels, and compensate the variation due to the size of the light-emitting area by adjusting the voltage of the written pixels.

In an embodiment of the present invention, the control unit 530 can also adjust the brightness of the sub-pixel 212C _x according to the brightness of the pixels 212A and 212B. In this way, the display panel 210 of the display 500 can have a smooth arc edge, and the brightness can be adjusted according to the effective area ratio of the sub-pixels through the control unit 530, so that the sub-pixel located at the periphery of the frame 220 is not caused by the light. The area of the light-emitting area of the area is small, resulting in a problem of lower actual brightness.

Through the displays 200 and 500, the prior art, the curved display panel can be avoided. The edges are jagged, resulting in poor visual performance and more efficient rendering of images than prior art displays. Although the display panels of the displays 500 and 200 are the same, the invention is not limited thereto. In other embodiments of the present invention, the display 500 can also be applied to other display panels. For example, the display panel of the display 500 can also set all the pixels located at the periphery of the frame 220 to have only a single color sub-pixel or both. The sub-pixels of the three colors, the display panel of the display 500 can also adjust the sub-pixels of the pixels located at the periphery of the frame 220 and their colors according to different standards, or the display panel of the display 500 can have only a single pixel. Sub-pixels, and the illuminating area of each pixel is the illuminating area of its sub-pixels. In detail, as long as the control unit 530 of the display 500 can still adjust the brightness according to the effective area ratio of the sub-pixel or pixel, the sub-pixel or pixel located at the periphery of the frame 220 can be avoided because the area of the light-emitting area is small. This leads to the problem of lower actual brightness, and the image can be rendered more efficiently than the prior art display with a smooth arc edge.

In summary, the display according to the embodiment of the present invention can be adjusted on the display surface. The brightness of the pixels on the edge of the board complements the prior art, where the edges of the curved display panel are jagged and cause poor visual effects.

The above description is only a preferred embodiment of the present invention, and the scope of the patent application according to the present invention is Equal variations and modifications are intended to be within the scope of the present invention.
