Detailed Description
The present specification provides a display apparatus and an ambient light generating method thereof, which can reduce the burden of eyes of a user without affecting visual effect and viewing quality while eliminating ambient glare and provide illumination on the back or around of the display apparatus. The above embodiments and other objects, features and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings.
Referring to fig. 1A to 1B, fig. 1A is a schematic diagram illustrating a front configuration of a display device 10 according to an embodiment of the invention, and fig. 1B is a schematic diagram illustrating a back configuration of the display device 10 of fig. 1A.
The display device 10 includes a screen 11 and a light supplementing 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 image signal 11s played by the display controller 11a and displaying the same in the display area 110. Wherein the display pixel units 111 are dispersed among a plurality of different areas in the display area 110; each display pixel unit 111 can emit a specific image color light L1 according to the received image signal 11s, so as to display an image 13 in the display area 110.
In some embodiments of the present specification, the screen 11 may be, but is not limited to, any one of a Liquid crystal display (Liquid CRYSTAL DISPLAY, LCD) panel, an Organic Light-Emitting Diode (OLED) panel, a Micro Light-Emitting Diode (Micro LED) panel, an Electronic paper display (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) that may emit different colors of light, such as red/green/blue (RGB) light, respectively, and each of the pixel sub-units may emit different colors (specific color temperature) of image light L1 in response to the received image signal 11s, and after mixing, display the image 13 in the display area 110.
For example, in the present embodiment, the displayed image 13 may be roughly divided into an intermediate image block 130 and peripheral image blocks 131, 132, 133 and 134. Each of the middle image block 130 and the peripheral image blocks 131, 132, 133 and 134 includes a plurality of display pixel units 111, respectively, and generates respective image color light L1 according to the image signal 11s played by the display controller 11a, and the middle image block 130 and the peripheral image blocks 131, 132, 133 and 134 are formed respectively after mixing, and then the image 13 is synthesized.
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 apart from the center point 110p of the display area 110 by a distance H1; the left edge 110c and the right edge 110d of the display area 110 are each spaced apart from the center point 110p of the display area 110 by a distance H2. The peripheral image blocks 131 and 132 may be areas extending from 1/10 to 1/5 of the distance H1 from the upper edge 110a and the lower edge 110b of the display area 110, respectively, toward the center point 110 p. The peripheral image areas 133 and 134 may be areas extending from 1/10 to 1/5 of the distance H2 from the left edge 110c and the right edge 110d of the display area 110, respectively, toward the center point 110 p. In practice, the image blocks 131, 132, 133 and 134 are 1/10 to 1/5 of the first distance from at least one edge (the upper edge 110a, the lower edge 110b, the left edge 110c or the right edge 110 d) of the display area 110.
Since the size of the image signal 11s played by the display controller 11a may be different from that of the screen 11, when the display pixel unit 111 of the display area 110 displays the image 13 in response to the image signal 11s played by the display controller 11a, non-luminous black edges (Letterboxing) may be formed on the outer side of the image 13 to the two sides of the upper edge 110a and the lower edge 110b or 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, black edges may be formed between the upper and lower edges 110a and 110b of the display area 110 and the peripheral image blocks 131 and 132. In other embodiments of the present disclosure, black edges may be formed between the left and right edges 110c and 110d of the display area 110 and the peripheral image blocks 133 and 134. In other embodiments of the present disclosure, black sides may be formed between four edges (upper edge 110a, lower edge 110b, left edge 110c, and right edge 110 d) of the display area 110 and the peripheral image blocks 131, 132, 133, and 134.
In the present embodiment, the black edge is formed as two black blocks located between the peripheral image blocks 131 and 132 and the upper and lower edges 110a and 110b, respectively. 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 plurality of display pixel units 111 located in the edge area 110t of the display area 110 will not emit light.
The light supplementing component 12 is located at the back surface 110k or the periphery of the display area 110, and is used for acquiring color information of peripheral image blocks 131, 132, 133 and 134 displayed in the display area 110, and generating a light LC1 with complementary color to illuminate the back surface 110k or the periphery of the display area 110 according to the acquired color information. The light compensating component 12 can generate a plurality of complementary colors of light LC1, which respectively form a color complementary relationship with a plurality of image color lights L1 of the display pixel unit 111 for displaying the peripheral image blocks 131, 132, 133 and 134 in the display area 110.
In some embodiments of the present disclosure, the light supplementing component 12 may include a light supplementing controller 120 and a plurality of light supplementing pixel units 121, 122, 123 and 124 respectively corresponding to the peripheral image blocks 131, 132, 133 and 134 in the image 13. The light compensating controller 120 generates a plurality of simulated color light information 141, 142, 143, and 144 according to the color information acquired from the respective peripheral image blocks 131, 132, 133, and 134, and supplies the simulated color light information to the corresponding light compensating pixel units 121, 122, 123, and 124 in the light compensating assembly 12, respectively, to generate a plurality of light compensating lights LC1 corresponding to the respective peripheral image blocks 130, 131, 132, and 133.
For example, in the present embodiment, the light compensation controller 120 directly receives the image signal 11s played by the display controller 11a, obtains the color information in each of the peripheral image blocks 131, 132, 133 and 134 from the image signal 11s, and generates a plurality of simulated color light information 141, 142, 143 and 144 according to the obtained color information, and provides the simulated color light information to the corresponding light compensation pixel units 121, 122, 123 and 124 of the light compensation component 12. Each of the light-compensating 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 different colors, such as red/green/blue (RGB) three colors, and may generate a plurality of light-compensating lights LC1 corresponding to the respective image blocks 131, 132, 133 and 134 according to the simulated color light information 140, 141, 142 and 143 provided by the light-compensating controller 120.
In some embodiments of the present disclosure, the plurality of light-compensating light LC1 generated by the light-compensating pixel units 121, 122, 123 and 124 can illuminate the back surface 110k or the periphery of the display area 110 synchronously with the image light L1 generated by the display pixel unit 111 at the respective image areas 131, 132, 133 and 134. When the display pixel unit 111 of the display area 110 generates 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 simultaneously illuminates the back surface 110k or the periphery of the display area 110 (as shown in fig. 1A and 1B).
In other embodiments, the light-compensating light LC1 generated by the light-compensating pixel units 121, 122, 123 and 124 and the image light L1 generated by the display pixel unit 111 can be used to illuminate the back surface 110k or the periphery of the display area 110 in a switching manner. When the display pixel unit 111 receives the switching signal, the illumination of the image color light L1 is stopped, and the light-compensating pixel units 121, 122, 123 and 124 are driven by the light-compensating controller 120 to generate the light-compensating light LC1 to illuminate the back surface 110k or the periphery of the display area 110.
Since the complementary color light LC1 generated by the light-compensating pixel units 121, 122, 123 and 124 can be used to illuminate the back surface 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 the 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 light, so that the content of the image 13 displayed in the display area 110 can be highlighted, the eyes of the user can be automatically focused on the display area 110, the brightness of the image color light L1 can be properly reduced, and the eye burden of the user can be reduced without affecting the ornamental quality.
However, the configuration of the display device 20 is not limited thereto. Referring to fig. 2A and 2B, fig. 2A is a schematic diagram illustrating a front configuration of a display device 20 according to another embodiment of the invention, and fig. 2B is a schematic diagram illustrating a back configuration of the display device 20 of fig. 2A. The configuration of display device 20 is generally similar to display device 10, with the primary difference being the manner in which display device 20 is used to obtain color information to generate a plurality of simulated color light information 241, 242, 243, and 244.
In this embodiment, the display device 20 further includes an emulator 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 display area 110 for displaying the peripheral image blocks 131, 132, 133 and 134, for obtaining the color information displayed by the peripheral image blocks 131, 132, 133 and 134, and generating a plurality of emulated color light information 241, 242, 243 and 244 by the emulator 25. Each of the light-compensating pixel units 121, 122, 123 and 124 can generate a plurality of light-compensating lights LC2 corresponding to the respective image blocks 131, 132, 133 and 134 according to the simulated 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 includes at least one photoelectric conversion device, such as a photodiode (photodiode), a charge-coupled device (CCD) c oupled device or an enhanced charge-coupled device (ICCD, intensified CCD), which can be used to capture optical information such as brightness, gray scale, color (RGB) and the like displayed by the peripheral image blocks 131, 132, 133 and 134, and convert the optical information into simulated color light information 241, 242, 243 and 244 by the simulator 25, which is provided to the respective light supplementing pixel units 221, 222, 223 and 224 corresponding to the respective image blocks 131, 132, 133 and 134, respectively, and emits multiple complementary lights LC2 of different colors (specific color temperatures) in response to the received simulated color light information 241, 242, 243 and 244.
Since the complementary color light LC2 generated by the light-compensating pixel units 221, 222, 223 and 224 can be used to illuminate the back surface 110k or the periphery of the display area 110, an additional backlight source is generated, so as to reduce the light contrast difference between the screen 11 and the surrounding environment, and achieve 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 light, so that the content of the image 13 displayed in the display area 110 can be highlighted, the eyes of the user can be automatically focused on the display area 110, the brightness of the image color light L1 can be properly reduced, and the eye burden of the user can be reduced without affecting the ornamental quality.
Referring to fig. 3, fig. 3 is a schematic view showing a partial cross-sectional structure of a display device 30 according to still 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 supplementing component 32 of the display device 30 is configured differently from the light supplementing component 12 of the display device 10.
The display device 30 includes a back surface 310k of the back plate 36 facing the display area 310 of the screen 31; and the light supplementing component 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 36b. The opening 36a of the back plate 36 is larger in size than the screen 31; the screen 31 is partially sleeved in the back plate 36, so that the back surface 310k of the display area 310 faces the bottom surface 36b of the back plate 36, and a gap or hole 37 is reserved between the opening 36a of the back plate 36 and the screen 31.
The light supplementing component 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 supplementing light LC3 by the same method as the aforementioned light supplementing component 12 and/or the aforementioned light supplementing component 22. The bottom surface 36b of the back plate 36 has a light reflecting function, and can reflect the complementary color light LC3 emitted by the light supplementing component 32, and the complementary color light LC3 is emitted 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 disclosure, a light-transmitting structure 38 may be disposed 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-transmitting structure 38 and exits from the edge 310a of the display area 310.
Because the complementary color light LC3 generated by the light supplementing component 32 can be used to illuminate the back surface 310k or the periphery of the display area 310, an additional backlight source is generated, so as to reduce the light contrast difference between the screen 31 and the surrounding environment, and achieve 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, so that the content of the image 33 displayed in the display area 310 can be highlighted, the eyes of the user can be automatically focused on the display area 310, the brightness of the image color light L3 can be properly reduced, and the eyes 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 capable of illuminating the back surface or the periphery of a display area by obtaining color information of an image area located in the display area and generating complementary color light with brightness corresponding to the display area according to the color information. Because the color lights generated on the back or around the display area are complementary with the display contents, the display contents 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 moderately reduced, the eye burden of a user is reduced under the condition that the ornamental quality is not affected, the environment glare is eliminated, and the back or periphery of the display device is illuminated.
