Background
When a general user is watching a television program or a movie, the indoor lighting device is usually turned off to eliminate glare caused by ambient light. However, the brightness of the display image is too high for human eyes in an unlit environment, and fatigue and acerbity of eyes are easily caused by long-term watching. Therefore, in the prior art, a backlight source is additionally installed behind a display screen to reduce the light contrast difference between the display screen and the surrounding environment, so as to reduce screen glare, maintain sufficient indoor visibility, and enable the eyes of a user to focus more easily to improve the definition of an image.
However, the backlight source applied to the back of the current display screen is usually a single color or is only an extension of the display screen and has a lower brightness relative to the display screen itself. Since the human eye tends to adapt to the brightness of the light around the display screen rather than the display screen itself, the user still cannot comfortably focus his or her eyes on the display screen for a long period of time.
Therefore, there is a need to design a new display device and an ambient light generating method thereof to overcome the above-mentioned drawbacks.

Detailed Description
The present specification is to provide a display device and an ambient light generating method thereof, which can reduce the eye burden of a user without affecting the visual effect and the viewing quality, simultaneously eliminate ambient glare, and provide illumination on the back or the periphery of the display device. In order to make the aforementioned embodiments, as well as other objects, features, and advantages of the present invention comprehensible, several preferred embodiments accompanied with figures are described in detail below.
Referring to fig. 1A to fig. 1B, fig. 1A is a schematic front configuration diagram of a display device 10 according to an embodiment of the invention, and fig. 1B is a schematic back configuration diagram of the display device 10 of fig. 1A.
The display device 10 includes a screen 11 and a fill light assembly 12. The screen 11 has a display controller 11a and a display area 110. The display area 110 includes a plurality of display pixel units 111 for responding to the video signal 11s played by the display controller 11a and displaying the video signal in the display area 110. The display pixel units 111 are dispersed in different areas of the display region 110; each display pixel unit 111 can emit a specific color light L1 according to the received image signal 11s, so as to display the image 13 in the display area 110.
In some embodiments of the present description, the screen 11 may be, but is not limited to, any one of a Liquid Crystal Display (LCD) panel, an Organic Light-Emitting Diode (OLED) panel, a Micro LED (Micro LED) panel, an Electronic Paper Display (EPD) panel, or an Electronic Ink (E-Ink) Display panel. Each display pixel unit 111 in the display area 110 may be, but is not limited to, a plurality of pixel sub-units (not shown) capable of emitting different color lights, such as red/green/blue (RGB) three color lights, and respectively emitting image color lights L1 with different colors (specific color temperatures) in response to the received image signal 11s, and after mixing, the image 13 is displayed in the display area 110.
For example, in the present embodiment, the displayed image 13 can be roughly divided into the middle image area 130 and the peripheral image areas 131, 132, 133 and 134. Each of the middle image block 130 and the peripheral image blocks 131, 132, 133 and 134 respectively includes a plurality of display pixel units 111, generates respective image color light L1 according to the image signal 11s played by the display controller 11a, mixes the light to form the middle image block 130 and the peripheral image blocks 131, 132, 133 and 134 respectively, and synthesizes the image 13.
In some embodiments of the present description, the display area 110 may be, for example, a rectangular area. The upper edge 110a and the lower edge 110b of the display area 110 are respectively spaced from the center point 110p of the display area 110 by a distance H1; the left and right edges 110c and 110d of the display area 110 are respectively spaced apart from the center point 110p of the display area 110 by a distance H2. The peripheral image areas 131 and 132 may be areas extending 1/10 to 1/5 from the center point 110p to the distance H1 from the upper edge 110a and the lower edge 110b of the display area 110, respectively. The peripheral image areas 133 and 134 may be areas extending 1/10 to 1/5 from the left edge 110c and the right edge 110d of the display area 110 to the center point 110p by a distance H2, respectively. In one implementation, image blocks 131, 132, 133, and 134 are a first distance 1/10-1/5 from at least one edge (top edge 110a, bottom edge 110b, left edge 110c, or right edge 110d) of display area 110.
Since the video signal 11s played by the display controller 11a and the screen 11 may have different sizes, when the display pixel units 111 of the display area 110 display the image 13 in response to the video signal 11s played by the display controller 11a, non-luminous black edges (lebttering) may be formed in the areas outside the image 13 to both sides of the upper edge 110a and the lower edge 110b or around the upper edge 110a, the lower edge 110b, the left edge 110c and the right edge 110d of the display area 110.
For example, in some embodiments of the present disclosure, a black border may be formed between the upper edge 110a and the lower edge 110b of the display area 110 and the peripheral image areas 131 and 132. In other embodiments of the present disclosure, the black border may be formed between the left edge 110c and the right edge 110d of the display area 110 and the peripheral image areas 133 and 134. In other embodiments of the present disclosure, black borders may be formed between four edges (the upper edge 110a, the lower edge 110b, the left edge 110c, and the right edge 110d) of the display area 110 and the peripheral image blocks 131, 132, 133, and 134.
In the present embodiment, the black border is formed by two black blocks respectively located between the peripheral image blocks 131 and 132 and the upper edge 110a and the lower edge 110 b. When the display pixel units 111 of the display area 110 generate the color image light L1 in response to the image signal 11s played by the display controller 11a to synthesize the image 13, the display pixel units 111 in the edge region 110t of the display area 110 do not emit light.
The light supplement component 12 is located on the back surface 110k or around the display area 110, and is configured to obtain color information of the peripheral image blocks 131, 132, 133, and 134 displayed in the display area 110, and generate a light supplement light LC1 to illuminate the back surface 110k or around the display area 110 according to the obtained color information. The light supplement component 12 can generate a plurality of complementary color lights LC1, which respectively form a color complementary relationship with the plurality of image color lights L1 of the display pixel unit 111 in the display area 110 for displaying the peripheral image blocks 131, 132, 133, and 134.
In some embodiments of the present disclosure, the fill-in light assembly 12 may include a fill-in light controller 120 and a plurality of fill-in light pixel units 121, 122, 123 and 124 respectively corresponding to the peripheral image blocks 131, 132, 133 and 134 in the image 13. The fill-in controller 120 generates a plurality of simulated color light information 141, 142, 143, and 144 according to the color information obtained from each of the peripheral image blocks 131, 132, 133, and 134, and provides the simulated color light information to the corresponding fill-in pixel units 121, 122, 123, and 124 of the fill-in module 12, respectively, so as to generate a plurality of fill-in light LC1 corresponding to each of the peripheral image blocks 130, 131, 132, and 133.
For example, in the present embodiment, the fill-in controller 120 directly receives the video signal 11s played by the display controller 11a, acquires the color information in each of the peripheral image blocks 131, 132, 133 and 134 from the video signal 11s, and generates a plurality of pieces of simulated color light information 141, 142, 143 and 144 according to the acquired color information, and provides the plurality of pieces of simulated color light information to the fill-in pixel units 121, 122, 123 and 124 corresponding to the fill-in device 12. Each of the fill-in pixel units 121, 122, 123 and 124 may be a pixel sub-unit (not shown) composed of a plurality of led dies capable of emitting light of different colors, such as red/green/blue (RGB) three-color light, and may generate a plurality of fill-in light LC1 corresponding to each of the image blocks 131, 132, 133 and 134 according to the emulated color light information 140, 141, 142 and 143 provided by the fill-in controller 120.
In some embodiments of the present disclosure, the light supplementing light LC1 generated by the light supplementing pixel units 121, 122, 123 and 124 and the image color light L1 generated by the display pixel unit 111 in each of the image blocks 131, 132, 133 and 134 can illuminate the back surface 110k or the periphery of the display area 110 synchronously. When the display pixel units 111 of the display area 110 generate the image color light L1 in response to the image signal 11s played by the display controller 11A to synthesize the image 13, the image color light L1 illuminates the back surface 110k or the periphery of the display area 110 (as shown in fig. 1A and fig. 1B).
In other embodiments, the light supplementing pixel units 121, 122, 123, and 124 generate the plurality of light supplementing colors LC1 and the display pixel unit 111 generates the image color light L1, which can illuminate the back surface 110k or the periphery of the display area 110 in a switchable manner. When the display pixel unit 111 receives the switching signal, the illumination of the image color light L1 is stopped, and the fill-in light controller 120 drives the fill-in pixel units 121, 122, 123, and 124 to generate a fill-in light LC1 to illuminate the back 110k or the periphery of the display area 110.
The complementary color light LC1 generated by the light supplementing pixel units 121, 122, 123, and 124 can be used to illuminate the back 110k or the periphery of the display area 110 to generate an additional backlight source, so as to reduce the light contrast difference between the screen 11 and its surrounding environment, and achieve the purposes of reducing screen glare and maintaining sufficient indoor visibility. The complementary color light LC1 and the image color light L1 generated by the peripheral image blocks 131, 132, 133 and 134 of the display area 110 are complementary color lights, and thus, the content of the image 13 displayed in the display area 110 can be highlighted, so that the eyes of the user can automatically focus on the display area 110, the brightness of the image color light L1 can be appropriately reduced, and the eye burden of the user can be reduced without affecting the viewing quality.
However, the configuration of the display device 20 is not limited thereto. Referring to fig. 2A and fig. 2B, fig. 2A is a schematic front configuration diagram of a display device 20 according to another embodiment of the invention, and fig. 2B is a schematic back configuration diagram of the display device 20 of fig. 2A. The configuration of the display device 20 is generally similar to the display device 10, with the primary difference being the manner in which the display device 20 is used to obtain color information to produce the plurality of emulated color light information 241, 242, 243, and 244.
In this embodiment, the display device 20 further includes a simulator 25 having a plurality of light sensing units 251, 252, 253, and 254, respectively disposed on the back surface 110k or the periphery of the display area 110, corresponding to the positions of the peripheral image blocks 131, 132, 133, and 134 displayed by the display area 110, for obtaining the color information displayed by the peripheral image blocks 131, 132, 133, and 134, and generating a plurality of simulated color light information 241, 242, 243, and 244 by the simulator 25. Each of the light compensation pixel units 121, 122, 123 and 124 can generate a plurality of complementary color lights LC2 corresponding to each of the image blocks 131, 132, 133 and 134 according to the simulation color light information 241, 242, 243 and 244 provided by the simulator 25.
In detail, each of the light sensing units 251, 252, 253, and 254 at least includes, but is not limited to, a photoelectric conversion device, such as a photodiode (photodiode), a charge-coupled device (CCD), or an enhanced CCD (ICCD), for capturing optical information such as brightness, gray scale, color (RGB) displayed by the peripheral image blocks 131, 132, 133, and 134, and converting the optical information into artificial color light information 241, 242, 243, and 244 by the emulator 25, which is provided to the light compensation pixel units 221, 222, 223, and 224 corresponding to the image blocks 131, 132, 133, and 134, respectively, and emits a plurality of complementary color lights LC2 with different colors (specific color temperatures) in response to the received artificial color light information 241, 242, 243, and 244.
The complementary color light LC2 generated by the light supplementing pixel units 221, 222, 223, and 224 can be used to illuminate the back 110k or the periphery of the display area 110, and an additional backlight source is generated to reduce the contrast difference between the screen 11 and its surrounding environment, thereby achieving the purposes of reducing screen glare and maintaining sufficient indoor visibility. The complementary color light LC2 and the image color light L1 generated by the peripheral image blocks 131, 132, 133 and 134 of the display area 110 are complementary color lights, and thus, the content of the image 13 displayed in the display area 110 can be highlighted, so that the eyes of the user can automatically focus on the display area 110, the brightness of the image color light L1 can be appropriately reduced, and the eye burden of the user can be reduced without affecting the viewing quality.
Referring to fig. 3, fig. 3 is a schematic cross-sectional view of a display device 30 according to another embodiment of the present invention. The configuration of the display device 30 is substantially similar to that of the display device 10, and the main difference is that the light supplement assembly 32 of the display device 30 is configured differently from the light supplement assembly 12 of the display device 10.
The display device 30 includes a back panel 36 facing the display area 310k of the screen 31; and the fill-in light assembly 32 is located between the back surface 310k of the display area 310 and the back plate 36. In this embodiment, the back plate 36 may be a housing structure including an opening 36a and a bottom surface 36 b. The opening 36a of the back plate 36 is larger in size than the screen 31; the screen 31 is partially received in the back plate 36 such that the back surface 310k of the display area 310 faces the bottom surface 36b of the back plate 36 and a gap or aperture 37 is left between the opening 36a of the back plate 36 and the screen 31.
The light supplement assembly 32 is disposed on the back surface 310k of the display area 310 and faces the bottom surface 36b of the back plate 36, and generates the light supplement light LC3 by the same method as the light supplement assembly 12 and/or the light supplement assembly 22. The bottom surface 36b of the back plate 36 has a light reflecting function, and can reflect the complementary color light LC3 emitted from the complementary light assembly 32, and emit the complementary color light LC3 from the gap 37 between the opening 36a of the back plate 36 and the screen 31 to the outside from the edge 310a of the display area 310. In some embodiments of the present description, a light-transmissive structure 38 may be provided in the gap 37 between the opening 36a of the back plate 36 and the screen 31, so that the complementary color light LC3 reflected by the bottom surface 36b passes through the light-transmissive structure 38 and exits from the edge 310a of the display region 310.
The complementary color light LC3 generated by the light supplement component 32 can be used to illuminate the back 310k or the periphery of the display area 310 to generate an additional backlight source, so as to reduce the light contrast difference between the screen 31 and its surrounding environment, thereby achieving the purposes of reducing screen glare and maintaining sufficient indoor visibility. The complementary color light LC3 and the image color light L3 generated by the peripheral image blocks (e.g., the peripheral image blocks 331 and 332) of the display area 310 are complementary color lights, and the content of the image 33 displayed in the display area 310 can be highlighted, so that the eyes of the user can automatically focus on the display area 310, the brightness of the image color light L3 can be appropriately reduced, and the eye burden of the user can be reduced without affecting the viewing quality.
In summary, the present invention provides a display device and an ambient light generating method thereof, which are configured to obtain color information of an image block located in a display area, and generate complementary color light having a brightness equivalent to that of the display area according to the color information to illuminate a back or a periphery of the display area. Because the color lights generated on the back or around the display area are complementary with the display content, the display content in the display area can be highlighted, and the eyes of the user can automatically focus on the display area. Meanwhile, the display brightness can be properly reduced, the eye burden of a user is reduced under the condition of not influencing the viewing quality, simultaneously the environment glare is eliminated, and the back or the periphery of the display equipment is illuminated.
