Description

electronic device

The present invention relates to an electronic device, and in particular to an electronic device with a luminous effect.

In an electronic device that can emit light, a backlight module can be used to provide a backlight source to display a backlight pattern, and the main appearance pattern can be observed through ambient light illumination. However, when the backlight module provides backlight, the appearance pattern may cause uneven color or brightness.

In order to solve the above problems, the compensation pattern can be additionally configured to complement the color or transmittance of the appearance pattern. Among them, in the practice of color complementation, the purpose is to return the two patterns to a neutral color (grayscale between pure black and pure white, without any color to avoid interfering with the display content), such as the complementary color of red It's cyan, and the two add together to become a colorless gray. In addition, in the approach of complementary transmittance, the purpose is to prevent the display content from being affected by the depth of the pattern. When the complementary colors are completed, patterns with different shades of gray will be produced. However, in order to eliminate the problem of uneven depth, the light-colored positions can only be darkened to the same color as the dark-colored positions, thus resulting in a significant decrease in the overall penetration rate.

This new creation provides an electronic device that can increase the total transmittance, thereby improving the optical effect and appearance pattern uniformity.

An embodiment of the present invention provides an electronic device, including a light-emitting layer, a first pattern layer, a compensation pattern layer, an optical layer, a second pattern layer and a substrate. The luminescent layer is used to provide an illumination beam. The first pattern layer includes a first pattern. The compensation pattern layer includes a compensation pattern and a first hollow area. The optical layer is used to allow at least part of the illumination beam to pass through and to reflect at least part of the ambient light beam. The second pattern layer includes a second pattern and a second hollow area. The color of the second pattern and the color of the compensation pattern are complementary colors. The light-emitting layer, the first pattern layer, the compensation pattern layer, the optical layer, the second pattern layer and the substrate are arranged along a stacking direction, and in the stacking direction, the compensation pattern does not overlap the second pattern.

In an embodiment of the present invention, the orthographic projection of the above-mentioned compensation pattern on the reference plane is immediately adjacent to the orthographic projection of the second pattern on the reference plane, and the extending direction of the reference plane is perpendicular to the stacking direction.

In an embodiment of the present invention, at least a part of the first hollow area overlaps the second hollow area in the above-mentioned stacking direction.

In an embodiment of the present invention, the above-mentioned optical layer is a semi-transmissive and semi-reflective optical element.

In an embodiment of the present invention, the above-mentioned compensation pattern and the second pattern form an adjacent pattern, and the transmittance value of the adjacent pattern is the average value of the transmittance of the compensation pattern and the transmittance of the second pattern. .

In an embodiment of the present invention, the above-mentioned adjacent patterns have uniform transmittance on the appearance of the electronic device.

Another embodiment of the present invention provides an electronic device including a light-emitting layer, a first pattern layer, a compensation pattern layer, an optical layer, a second pattern layer and a substrate. The luminescent layer is used to provide an illumination beam. The first pattern layer includes a first pattern. The compensation pattern layer includes a compensation pattern and a first hollow area. The optical layer is used to allow at least part of the illumination beam to pass through and to reflect at least part of the ambient light beam. The second pattern layer includes a second pattern and a second hollow area. The color of the second pattern and the color of the compensation pattern are complementary colors. The light-emitting layer, the first pattern layer, the compensation pattern layer, the optical layer, the second pattern layer and the substrate are arranged along a stacking direction, and in the stacking direction, the compensation pattern completely overlaps the second pattern.

In an embodiment of the present invention, in the above-mentioned stacking direction, the first hollow area completely overlaps the second hollow area.

In an embodiment of the present invention, the above-mentioned optical layer is a semi-transmissive and semi-reflective optical element.

In an embodiment of the present invention, the above-mentioned compensation pattern and the second pattern form an overlay pattern, and the transmittance of the overlay pattern is the accumulation of the transmittance of the compensation pattern and the transmittance of the second pattern.

In an embodiment of the present invention, the above-mentioned overlay pattern has uniform transmittance on the appearance of the electronic device.

Based on the above, in the electronic device created by the present invention, the electronic device sequentially includes a light-emitting layer, a first pattern layer, a compensation pattern layer, an optical layer, a second pattern layer and a substrate along the stacking direction. Wherein, the compensation pattern layer includes a compensation pattern and a first hollow area, the second pattern layer includes a second pattern and a second hollow area, and the color of the second pattern and the color of the compensation pattern are complementary colors. In the stacking direction, the compensation pattern does not overlap or completely overlaps the second pattern. Therefore, through the blank design of the first hollow region and the second hollow region, the transmittance formed by the overlay pattern formed by the compensation pattern and the second pattern and its light mixing can be increased. In this way, the optical effect and appearance pattern uniformity can be improved.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, examples are given below and explained in detail with the accompanying drawings.

FIG. 1 is a schematic diagram of the appearance of an electronic device according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of an electronic device according to an embodiment of the present invention. Please refer to Figure 1 and Figure 2. This embodiment provides an electronic device 100 that sequentially includes a light-emitting layer 110, a first pattern layer 120, a compensation pattern layer 130, an optical layer 140, a second pattern layer 150 and a substrate 160 along a stacking direction A1. . The electronic device 100 is, for example, an electronic clock. An internal illumination beam L1 can be transmitted out of the electronic device 100 toward the user to display a backlight pattern (such as clock numbers), and an ambient light beam L2 can be used to illuminate the electronic device 100 To reflect the appearance pattern (such as surface texture and color). However, the present invention does not limit the type of the electronic device 100 . The substrate 160 is, for example, glass or plastic, used to cover the internal structure, but the invention is not limited thereto.

The light-emitting layer 110 is used to provide the illumination beam L1 toward the stacking direction A1. In this embodiment, the light-emitting layer 110 is, for example, a backlight module, but the invention is not limited thereto. When the light-emitting layer 110 is activated, the electronic device 100 exhibits a transmission mode, and the user obtains the backlight pattern and appearance pattern through the illumination beam L1 and the ambient light beam L2. When the light-emitting layer 110 is turned off, the electronic device 100 exhibits a reflection mode, and the user only obtains the appearance pattern through the ambient light beam L2.

The first pattern layer 120 includes a first pattern 122 . For example, in this embodiment, the first pattern layer 120 is the backlight pattern layer of the electronic device 100, and the first pattern 122 is the backlight pattern, such as electronic numbers of an electronic clock. Therefore, the first pattern layer 120 can change the first pattern 122 through electrical control. When the electronic device 100 is in the reflective mode, the user cannot obtain the first pattern 122 (ie, the aforementioned backlight pattern).

The optical layer 140 is used to allow at least a portion of the illumination beam L1 to pass through, and to reflect at least a portion of the ambient light beam L2. In other words, for the pattern structure located on the optical layer 140 facing the light-emitting layer 110, if the brightness of L1 is much greater than L2, the user cannot obtain its pattern through the ambient light beam L2, while for the pattern structure located on the optical layer 140 facing away from the light-emitting layer 110, The user can obtain its pattern through the ambient light beam L2. In this embodiment, the optical layer 140 is, for example, a semi-transmissive and semi-reflective optical element, but the invention is not limited thereto.

FIG. 3 is a schematic view of the second pattern of the electronic device of FIG. 2 in the front direction. FIG. 4 is a schematic diagram of the compensation pattern of the electronic device of FIG. 2 in the front direction. FIG. 5 is a schematic diagram of the second pattern and the compensation pattern of the electronic device of FIG. 2 in the front direction. FIG. 6 is a schematic diagram of adjacent patterns of the electronic device of FIG. 2 in the front direction. Please refer to Figure 2 to Figure 6. The second pattern layer 150 includes a second pattern 152 and a second hollow area 154 . In this embodiment, the second pattern layer 150 is the main pattern layer of the electronic device 100, and the second pattern 152 is the main appearance pattern of the electronic device 100, such as the appearance pattern of an electronic clock. The second hollow area 154 is a blank area suitable for allowing the light beam to completely pass through. Therefore, regardless of whether the electronic device 100 is in the transmission mode or the reflection mode, the user can obtain the second pattern 152 through the ambient light beam L2.

The compensation pattern layer 130 includes a compensation pattern 132 and a first hollow area 134 . In this embodiment, the compensation pattern layer 130 is a pattern layer used to compensate the color of the second pattern layer 150 in the electronic device 100. Therefore, the color of the compensation pattern 132 and the color of the second pattern 152 are complementary colors. The first hollow area 134 is similar to the second hollow area 154 and is a blank area suitable for allowing the light beam to completely pass through. Therefore, when the electronic device 100 is in the transmission mode, the user can obtain the adjacent pattern B1 mixed with the second pattern 152 and the compensation pattern 132 through the illumination beam L1, as shown in FIG. 6 .

In this embodiment, the compensation pattern 132 does not overlap the second pattern 152 in the stacking direction A1. Specifically, in this embodiment, the orthographic projection of the compensation pattern 132 on the reference plane C1 is immediately adjacent to the orthographic projection of the second pattern 152 on the reference plane C1, where the extending direction of the reference plane C1 is perpendicular to the stacking direction A1. Therefore, the compensation pattern 132 and the second pattern 152 will be closely adjacent to each other, as shown in FIG. 5 . In addition, in the stacking direction A1, at least a part of the first hollow area 134 overlaps the second hollow area 154. Therefore, the pattern layer of this embodiment has a blank area through which the illumination beam L1 can completely pass, thereby improving the overall transmittance.

In detail, the gray scale value of the adjacent pattern B1 may be defined by the addition of the gray scale value of the compensation pattern 132 and the gray scale value of the second pattern 152 . For example, in this embodiment, the second pattern 152 includes a first sub-pattern 152_1, a second sub-pattern 152_2, a third sub-pattern 152_3 and a fourth sub-pattern 152_4 in four different colors, which correspond to The grayscale values are, for example: (255,0,0), (0,255,0), (0,0,255), (255,0,255). The compensation pattern 132 includes four types of first sub-compensation pattern 132_1, second sub-compensation pattern 132_2, third sub-compensation pattern 132_3 and fourth sub-compensation pattern 132_4 that can compensate the colors of the first sub-pattern 152_1 to the fourth sub-pattern 152_4. The corresponding gray scale values are, for example: (0,255,255), (255,0,255), (255,255,0), (0,255,0). Since the compensation pattern 132 and the second pattern 152 are arranged closely, when the illumination beam L1 penetrates the second pattern 152 and the compensation pattern 132 respectively, the compensation pattern 132 and the second pattern 152 that are adjacent and corresponding to each other can be regarded as opposite. The corresponding grayscale values of adjacent pattern B1 are: (128,128,128). In other words, the adjacent pattern B1 has uniform transmittance in the appearance of the electronic device 100 . Then, through the blank design of the first hollow area 134 and the second hollow area 154, the gray scale value formed by the adjacent pattern B1 and its mixed light can be made higher. In this way, the total transmittance can be increased upward, thereby improving the optical effect and appearance pattern uniformity.

FIG. 7 is a schematic cross-sectional view of an electronic device according to another embodiment of the present invention. FIG. 8 is a schematic view of the second pattern of the electronic device of FIG. 7 in the front direction. FIG. 9 is a schematic diagram of the compensation pattern of the electronic device of FIG. 7 in the front direction. FIG. 10 is a schematic diagram of the overlay pattern of the electronic device of FIG. 7 in the front direction. Please refer to Figure 7 to Figure 10. The electronic device 100A of this embodiment is similar to the electronic device 100 shown in FIG. 2 . The difference between the two is that in this embodiment, the designs of the compensation pattern layer 130A and the second pattern layer 150A of the electronic device 100A are different. In this embodiment, in the stacking direction A1, the compensation pattern 132A of the compensation pattern layer 130A completely overlaps the second pattern 152A of the second pattern layer 150A. Specifically, in this embodiment, the orthographic projection of the compensation pattern 132A on the reference plane C1 completely overlaps the orthographic projection of the second pattern 152A on the reference plane C1. In other words, the first hollow area 134 of the compensation pattern layer 130A also completely overlaps the second hollow area 154 of the second pattern layer 150A.

Therefore, based on the above configuration design, the grayscale value of the superimposed pattern B2 can be defined by the grayscale value of the compensation pattern 132A and the accumulated grayscale value of the second pattern 152A. For example, in this embodiment, the second pattern 152A includes a first sub-pattern 152_1, a second sub-pattern 152_2, a third sub-pattern 152_3 and a fourth sub-pattern 152_4 in four different colors, which correspond to The grayscale values are, for example: (255,0,0), (0,255,0), (0,0,255), (255,0,255). The compensation pattern 132A includes four types of first sub-compensation pattern 132_1, second sub-compensation pattern 132_2, third sub-compensation pattern 132_3 and fourth sub-compensation pattern 132_4 that can compensate the colors of the first sub-pattern 152_1 to the fourth sub-pattern 152_4. The corresponding gray scale values are, for example: (0,255,255), (255,0,255), (255,255,0), (0,255,0). Since the compensation pattern 132A and the second pattern 152A are arranged in an overlapping manner, when the illumination beam L1 penetrates the second pattern 152A and the compensation pattern 132A respectively, the grayscale values of the overlay pattern B2 are: (0,0,0). In other words, the overlay pattern B2 has uniform transmittance in the appearance of the electronic device 100A. Then, through the blank design of the first hollow area 134 and the second hollow area 154, the gray scale value formed by the superimposed pattern B2 and its mixed light can be made higher. In this way, the total transmittance can be increased upward, thereby improving the optical effect and appearance pattern uniformity.

To sum up, in the electronic device created by the present invention, the electronic device includes a light-emitting layer, a first pattern layer, a compensation pattern layer, an optical layer, a second pattern layer and a substrate in order along the stacking direction. Wherein, the compensation pattern layer includes a compensation pattern and a first hollow area, the second pattern layer includes a second pattern and a second hollow area, and the color of the second pattern and the color of the compensation pattern are complementary colors. In the stacking direction, the compensation pattern does not overlap or completely overlaps the second pattern. Therefore, through the blank design of the first hollow region and the second hollow region, the transmittance formed by the overlay pattern formed by the compensation pattern and the second pattern and its light mixing can be increased. In this way, the optical effect and appearance pattern uniformity can be improved.

Although the embodiments of the present invention have been disclosed above, they are not intended to limit the invention. Anyone with ordinary knowledge in the technical field can make some modifications and changes without departing from the spirit and scope of the invention. Therefore, the scope of protection of this new creation shall be determined by the scope of the patent application attached.
