Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, fig. 2A and fig. 2B, fig. 1 is a schematic diagram of a display device 100 according to an embodiment of the invention, fig. 2A is a schematic diagram of a color sensor 131 of the color corrector 130 of fig. 1 detecting artificial light color information M2 of analog light L2, and fig. 2B is a schematic diagram of a color sensor 131 of the color corrector 130 of fig. 1 detecting picture light color information M1 of picture light L1.
The display apparatus 100 includes a display 110, a color correction auxiliary module 120, a color corrector 130, and a controller 140. The display 100 is configured to display a picture light L1, the color correction assistant module 120 is detachably disposed on the display 110, when the color correction assistant module 120 is not disposed on the display 110, the color corrector 130 is configured to detect mixed light color information M3' of mixed light L3 ' of the picture light L1 and the ambient light L3, and the controller 140 is configured to obtain picture light color difference information Δ M1 between the mixed light color information M3' and the selected artificial light color information M2; the difference value between the picture color difference information Δ M1 and the picture color difference information M1 is obtained, and the color of the picture light L1 of the display 110 is corrected according to the difference value.
Next, the structure and the position relationship of the display 110, the color correction auxiliary module 120, the color corrector 130 and the controller 140 will be specifically described.
As shown in fig. 1, 2A and 2B, the display 110 has a display surface 110s, wherein the display surface 110s can emit the picture light L1. The color correction assistant module 120 is detachably disposed on the display 110. The color correction auxiliary module 120 includes a light shielding plate 121 and at least one light source, and the embodiment of the invention takes three light sources, i.e., a first light source 122, a second light source 123 and a third light source 124 as an example, but the embodiment of the invention does not limit the number of the light sources. The first light source 122, the second light source 123 and the third light source 124 may be disposed on the light shielding plate 121 and configured to emit the analog light L2 to irradiate the accommodating space SP 1. The shielding plate 121 is disposed around the display surface 110s, and forms an accommodating space SP1 opposite to the display surface 110 s.
The first light source 122, the second light source 123 and the third light source 124 may surround the display surface 110s, so that the light emitting patterns of the first light source 122, the second light source 123 and the third light source 124 may simulate (or approach) the ambient light pattern. The ambient light pattern herein is, for example, an illumination pattern of the display 110 by sunlight, indoor light, light emission of peripheral electronic devices, or light other than the picture light L1. In one embodiment, the first light source 122, the second light source 123 and the third light source 124 can be arranged in n-shape. For example, the first and second light sources 122 and 123 are disposed adjacent to the first and second sides 121e1 and 121e2 of the light shielding plate 121, respectively, and the third light source 124 is disposed adjacent to the third side 121e3 of the light shielding plate 121. The third side 121e3 extends between the first side 121e1 and the second side 121e2, for example, the third side 121e3 may be substantially perpendicular to the first side 121e1 and/or the second side 121e 2. In another embodiment, at least one of the second light source 123 and the third light source 124 may be omitted from the color correction auxiliary module 120, and the first light source 122 may be disposed on the second side 121e2 or the third side 121e3 instead. The embodiment of the invention does not limit the number and/or configuration mode of the light sources, as long as the light sources can simulate the irradiation mode of the ambient light. In addition, although not shown, the first light source 122, the second light source 123 and the third light source 124 may be connected to a port (for example, a USB port) of the display 110 through at least one connection line, wherein the port may be electrically connected to the controller 140 through an internal circuit of the display 110.
In the present embodiment, the color corrector 130 may be configured on the display 110. In another embodiment, however, the color corrector 130 may be disposed on the mask 121, in which case the color corrector 130 becomes a sub-component of the color correction assistance module 120. As shown in fig. 2A, the color corrector 130 includes a color sensor 131 and has an incident surface 130s, the incident surface 130s faces the display surface 110s, the incident surface 130s can selectively receive at least one of the light ray analog light L2 and the picture light L1, and the color sensor 131 detects the color information of the received light rays accordingly.
The controller 140 is disposed in the display 110, for example. In another embodiment, the controller 140 may be configured on the color correction assistance module 120. The controller 140 is electrically connected to the display 110, the first light source 122, the second light source 123, the third light source 124 and the color corrector 130, and is configured to: (1) control the display 110 to emit or not emit the picture light L1; (2) controlling the light color of the picture light L1; (3) controlling the light source to emit or not to emit the analog light L2; and (4) storing the light color information detected by the color corrector 130.
When the color correction assistant module 120 is disposed on the display 110, the color corrector 130 can detect the color information of the image light L1 and the color information of the simulated light L2 for later color correction. As further illustrated in fig. 3 below.
Referring to fig. 3, fig. 3 is a flowchart illustrating a process of collecting color information by using the color correction assistant module 120 and the color corrector 130 of fig. 1. The steps S110 and S120 are completed by controlling the light emitting mode of the display 110 and the light emitting mode of the light source by the controller 140, for example.
In step S110, as shown in fig. 2A, when the display 110 does not emit the screen light L1 and the light source (at least one of the first light source 122, the second light source 123 and the third light source 124) emits the analog light L2, the color sensor 131 of the color corrector 130 detects the analog light color information M2 of the analog light L2.
In step S120, the color sensor 131 of the color corrector 130 detects the picture light color information M1 of the picture light L1 when the display 110 emits the picture light L1 and the light sources (the first light source 122, the second light source 123 and the third light source 124) do not emit the analog light L2. In the embodiment, the color of the simulated light L2 in step S110 is identical to the color of the picture light L1 in step S120. In the embodiment, the color of the analog light L2 and the color of the picture light L1 are the color of the primary color of the color system, such as red, green or blue, but the embodiment of the invention is not limited to the RGB color system.
Steps S110 and S120 in fig. 3 are a process for collecting a light color (e.g., a light color of a color coordinate point on a color system). In another embodiment, steps S110 and S120 of fig. 3 may be repeated to collect color information of a plurality of different colors (e.g., colors of a plurality of color coordinate points on a color system). For example, in step S110, under a plurality of simulated lights L2 with different colors, the color sensor 131 detects a plurality of corresponding simulated light color information M2; in step S120, under the plurality of picture lights L1 with different light colors, the color sensor 131 detects the corresponding plurality of picture light color information M1, and then the controller 130 stores the plurality of picture light color information M1 and the plurality of simulated light color information M2. For example, the red, green and blue (RGB) color system may repeat steps S110 and S120 of fig. 3, and the artificial light color information M2 and the picture light color information M1 are collected for all combinations of a plurality of gray scale values (e.g., 256 levels) of red light, a plurality of gray scale values (e.g., 256 levels) of green light, and a plurality of gray scale values (e.g., 256 levels) of blue light.
In step S130, the controller 140 stores the collected artificial light color information M2 and the picture light color information M1 for later color correction. In addition, the simulation light color information M2 and the picture light color information M1 may be stored in the controller 140, or stored in a memory (not shown) electrically connected to the controller 140.
The process of FIG. 3 can be executed in the initial stage of the display 110 (e.g., the first time the display 110 is newly purchased, or the first few times the display 110 is newly purchased and used after being powered on). The process of fig. 3 may be performed before entering the consumer market, or after entering the consumer market and being purchased by the consumer, but the embodiment of the present invention is not limited thereto. In another embodiment, the process of FIG. 3 may also be performed after a period of use of the display 110 (e.g., days, weeks, months, or years).
Referring to fig. 4, fig. 5 and fig. 6, fig. 4 is a schematic diagram of the display apparatus 100 of fig. 1 with the light shielding plate 121 and the light source removed, fig. 5 is a schematic diagram of the color sensor 131 of the color corrector 130 of fig. 1 detecting mixed light color information M3' of the mixed light L3 ' of the picture light L1 ' and the ambient light L3, and fig. 6 is a flowchart of correcting picture colors by using the display apparatus 100 of fig. 4.
After the display 110 is used for a period of time or due to some factors, the color of the picture light L1 'emitted from the display surface 110s of the display 110 is different from the color information of the picture light L1 collected in fig. 3, for example, various display picture quality changes or degradations such as color shift or color difference of the picture light L1' occur compared with the picture light L1. The color correction method of the embodiment of the invention can improve the problem of the change of the quality of the display picture, and the corrected display quality can be recovered to the color information collected based on the flow of the figure 3 as far as possible. Please refer to the following description.
The color correction flow of FIG. 6 may be performed when the color correction assistance module 120 is not configured on the display 110; in other words, the color correction auxiliary module 120 is not needed when the color correction flow of fig. 6 is executed.
In step S210, the color sensor 131 of the color corrector 130 detects mixed light color information M3 'of the mixed light of the picture light L1' and the ambient light L3. The ambient light L3 is, for example, sunlight, indoor lighting, light emitted from peripheral electronic devices, or light other than the screen light L1'.
In step S220, the controller 140 obtains the picture light color difference information M1 between the mixed light color information M3' and the selected artificial light color information M2 a. In an embodiment, the controller 140 selects the simulated light color information M2 closest to and greater than the mixed light color information M3' from the plurality of stored simulated light color information M2 as the selected simulated light color information M2 a.
In step S230, the controller 140 calculates the picture color difference information M1 and the picture color difference information M1 to obtain a difference value between the picture color difference information M1 and the picture color difference information M1.
In step S240, the controller 140 corrects the color of the picture light L1' of the display 110 according to the difference value. For example, the controller 140 adds or subtracts the difference value to or from the color information of the picture light L1 'so that the color information of the picture light L1' compensated for the difference value approaches the color information of the picture light L1.
As can be seen from steps S210, S230, and S240, the light shielding plate 121 and the light sources (the first light source 122, the second light source 123, and the third light source 124) are not needed in the color correction process, and the controller 140 performs the color correction on the image light L1 according to the mixed light color information M3 'detected by the color corrector 130, the simulation light color information M2 stored in the controller 140, and the image light color information M1, so that the image light L1' returns/approaches the color information collected based on the process of fig. 3. That is, the color information of the corrected picture light L1' is returned to/approximated to the color information of the picture light L1. In the color correction process, the light shielding plate 121 and the light sources (the first light source 122, the second light source 123 and the third light source 124) are not required to be additionally arranged on the display 110, and the color correction can be rapidly realized through computer operation.
In the color information collection process of the above embodiment, the 1 st stored simulation light color information M2 and the picture light color information M1 are used as the reference for correction. However, in other embodiments, the color information of the display 110 (the simulated light color information M2 and the picture light color information M1) can be collected at different times by using the color information collection process of fig. 3, and the controller 140 can replace the previously stored color information with the latest collected color information (the simulated light color information M2 and the picture light color information M1) and use the latest collected color information as the reference for correcting the picture color of the display 110 at a later date.
In summary, the color correction auxiliary module, the display device and the color correction method provided by the invention are characterized in that the color correction auxiliary module is detachably disposed on the display, the display has a display surface, the color correction auxiliary module includes a light shielding plate and a first light source, the light shielding plate is disposed around the display surface and forms an accommodating space relative to the display surface, and the first light source is disposed on the light shielding plate and is used for emitting the analog light to irradiate the accommodating space, so that the display color of the display can be adjusted and the accuracy of color correction can be prevented from being influenced by the ambient light.
