Description

Technical Field

[0001] The utility model relates to an electronic device, and particularly to an electronic device with a light-emitting effect. Background Art

[0002] In a light-emitting electronic device, a backlight module can be used to provide a backlight source to display a backlight pattern, and the main appearance pattern can be observed by irradiating with ambient light. However, when the backlight module provides the backlight source, the appearance pattern will cause uneven color or brightness.

[0003] To solve the above problems, a compensation pattern can be additionally configured to complement the color or transmittance of the appearance pattern. Among them, in the method of color complementation, the purpose is to make the two patterns return to a neutral color (the gray scale between pure black and pure white, without any color to avoid interfering with the display content) after being added together. For example, the complementary color of red is cyan, and the two added together become a colorless gray. In addition, in the method of transmittance complementation, the purpose is to make the display content not affected by the depth of the pattern. When the color complementation is completed, patterns with different gray scale depths will be generated. However, in order to eliminate the problem of uneven depth, only the color of the light position can be deepened to the same as that of the dark position, resulting in a significant decrease in the overall transmittance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an electronic device, which can improve the total transmittance, and further improve the optical effect and the uniformity of the appearance pattern.

[0005] An embodiment of the utility model 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 light-emitting 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 a part of the illumination beam to pass through and reflect at least a part of the ambient beam. The second pattern layer includes a second pattern and a second hollow area. The color of the second pattern is complementary to the color of the compensation pattern. 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. In the stacking direction, the compensation pattern does not overlap with the second pattern.

[0006] In an embodiment of the utility model, the orthographic projection of the above-mentioned compensation pattern on the reference plane is 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.

[0007] In an embodiment of the utility model, in the above-mentioned stacking direction, at least a part of the first hollow area overlaps with the second hollow area.

[0008] In an embodiment of the present utility model, the above-mentioned optical layer is a semi-transmissive and semi-reflective optical element.

[0009] In an embodiment of the present utility model, the above-mentioned compensation pattern and the second pattern form an adjacent pattern, and the transmittance value of the adjacent pattern is the average of the transmittance of the compensation pattern and the transmittance of the second pattern.

[0010] In an embodiment of the present utility model, the above-mentioned adjacent pattern has a uniform transmittance on the appearance of the electronic device.

[0011] Another embodiment of the present utility model 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 light-emitting 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 a part of the illumination beam to pass through and reflect at least a part of the ambient beam. The second pattern layer includes a second pattern and a second hollow area. The color of the second pattern is complementary to the color of the compensation pattern. Wherein 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.

[0012] In an embodiment of the present utility model, in the above-mentioned stacking direction, the first hollow area completely overlaps the second hollow area.

[0013] In an embodiment of the present utility model, the above-mentioned optical layer is a semi-transmissive and semi-reflective optical element.

[0014] In an embodiment of the present utility model, the above-mentioned compensation pattern and the second pattern form a superimposed pattern, and the transmittance of the superimposed pattern is the sum of the transmittance of the compensation pattern and the transmittance of the second pattern.

[0015] In an embodiment of the present utility model, the above-mentioned superimposed pattern has a uniform transmittance on the appearance of the electronic device.

[0016] Based on the above, in the electronic device of the present utility model, 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. Among them, 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 is complementary to the color of the compensation pattern. 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 area and the second hollow area, the transmittance of the superimposed pattern formed by the compensation pattern and the second pattern and the mixed light thereof can be increased. In this way, the optical effect and the uniformity of the appearance pattern can be improved.

[0028] Figure 1 It is a schematic external view of an electronic device according to an embodiment of the present utility model. Figure 2 It is a schematic cross-sectional view of an electronic device according to an embodiment of the present utility model. Please refer to Figure 1 and Figure 2。This embodiment provides an electronic device 100, which 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, and can transmit the electronic device 100 toward the user direction through an internal illumination beam L1 to display a backlight pattern (such as the numbers of the clock), and irradiate the electronic device 100 through an ambient beam L2 to reflect an appearance pattern (such as the external 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, and is used to cover the internal structure, but the present invention is not limited thereto.

[0029] The light-emitting layer 110 is used to provide the illumination beam L1 along the stacking direction A1. In this embodiment, the light-emitting layer 110 is, for example, a backlight module, but the present invention is not limited thereto. When the light-emitting layer 110 is activated, the electronic device 100 presents a transmissive mode, and the user obtains the backlight pattern and the appearance pattern through the illumination beam L1 and the ambient beam L2. When the light-emitting layer 110 is turned off, the electronic device 100 presents a reflective mode, and the user only obtains the appearance pattern through the ambient beam L2.

[0030] 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 the 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 presents a reflective mode, the user cannot obtain the first pattern 122 (i.e., the aforementioned backlight pattern).

[0031] The optical layer 140 is used to allow at least a part of the illumination beam L1 to pass through and reflect at least a part of the ambient beam L2. In other words, for the pattern structure of the optical layer 140 facing the light-emitting layer 110, if the brightness of L1 is much greater than that of L2, the user cannot obtain its pattern through the ambient beam L2, and for the pattern structure of the optical layer 140 facing away from the light-emitting layer 110, the user can obtain its pattern through the ambient beam L2. In this embodiment, the optical layer 140 is, for example, a transflective optical element, but the present invention is not limited thereto.

[0032] Figure 3 is Figure 2 A schematic diagram of the second pattern of the electronic device in the front view direction. Figure 4 is Figure 2 A schematic diagram of the compensation pattern of the electronic device in the front view direction. Figure 5 is Figure 2 A schematic diagram of the second pattern and the compensation pattern of the electronic device in the front view direction. Figure 6 is Figure 2Schematic diagram of adjacent patterns of the electronic device in the front view direction. Please refer to Figures 2 to 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 outer texture of an electronic clock. The second hollow area 154 is a blank area suitable for allowing the light beam to pass through completely. Therefore, regardless of whether the electronic device 100 presents a transmissive mode or a reflective mode, the user can obtain the second pattern 152 through the ambient light beam L2.

[0033] 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 is complementary to the color of the second pattern 152. 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 pass through completely. Therefore, when the electronic device 100 presents a transmissive mode, the user can obtain the adjacent pattern B1 formed by mixing the second pattern 152 and the compensation pattern 132 through the illumination light beam L1, as Figure 6 shown.

[0034] In this embodiment, in the stacking direction A1, the compensation pattern 132 does not overlap the second pattern 152. Specifically, in this embodiment, the orthographic projection of the compensation pattern 132 on the reference plane C1 is adjacent to the orthographic projection of the second pattern 152 on the reference plane C1, where the extension 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 arranged adjacently, as Figure 5 shown. 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 in this embodiment has a blank area that allows the illumination light beam L1 to pass through completely, thereby improving the overall transmittance.

[0035] Specifically, the gray scale value of the adjacent pattern B1 can 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 with four different colors, and their corresponding gray scale values are respectively: (255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 0, 255). The compensation pattern 132 includes a first sub-compensation pattern 132_1, a second sub-compensation pattern 132_2, a third sub-compensation pattern 132_3, and a fourth sub-compensation pattern 132_4 that can compensate for the colors of the first sub-pattern 152_1 to the fourth sub-pattern 152_4, and their corresponding gray scale values are respectively: (0, 255, 255), (255, 0, 255), (255, 255, 0), (0, 255, 0). Since the compensation pattern 132 and the second pattern 152 are arranged adjacent to each other, when the illumination beam L1 penetrates the second pattern 152 and the compensation pattern 132 respectively, the adjacent and mutually corresponding complementary compensation pattern 132 and the second pattern 152 can be regarded as the adjacent pattern B1, and their corresponding gray scale values are both: (128, 128, 128). In other words, the adjacent pattern B1 has a uniform transmittance on the appearance of the electronic device 100. Through the blank design of the first hollow area 134 and the second hollow area 154, the gray scale value formed after mixing the adjacent pattern B1 with it can be increased. In this way, its total transmittance can be improved upward, thereby improving the optical effect and the uniformity of the appearance pattern.

[0036] Figure 7 A cross-sectional schematic diagram of an electronic device according to another embodiment of the present invention. Figure 8 is Figure 7 A schematic diagram of the second pattern of the electronic device in the front view direction. Figure 9 is Figure 7 A schematic diagram of the compensation pattern of the electronic device in the front view direction. Figure 10 is Figure 7 A schematic diagram of the superimposed pattern of the electronic device in the front view direction. Please refer to Figures 7 to 10 . The electronic device 100A of this embodiment is similar to Figure 2The displayed electronic device 100. The difference between the two is that in this embodiment, the design of the compensation pattern layer 130A and the second pattern layer 150A of the electronic device 100A is 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 region 134 of the compensation pattern layer 130A also completely overlaps the second hollow region 154 of the second pattern layer 150A.

[0037] Therefore, based on the above configuration design, the gray scale value of the superimposed pattern B2 can be defined by the gray scale value of the compensation pattern 132A and the cumulative gray scale 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 with four different colors, and their corresponding gray scale values are, for example: (255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 0, 255). The compensation pattern 132A includes a first sub-compensation pattern 132_1, a second sub-compensation pattern 132_2, a third sub-compensation pattern 132_3, and a fourth sub-compensation pattern 132_4 that can compensate for the colors of the first sub-pattern 152_1 to the fourth sub-pattern 152_4, and their 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, the gray scale value of the superimposed pattern B2 when the illumination beam L1 penetrates the second pattern 152A and the compensation pattern 132A respectively is: (0, 0, 0). In other words, the superimposed pattern B2 has a uniform transmittance on the appearance of the electronic device 100A. Through the blank design of the first hollow region 134 and the second hollow region 154, the gray scale value formed after mixing with the superimposed pattern B2 can be increased. In this way, the total transmittance can be improved, thereby improving the optical effect and the uniformity of the appearance pattern.

[0038] In summary, in the electronic device of the present utility model, 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. Among them, 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 is complementary to the color of the compensation pattern. In the stacking direction, the compensation pattern does not overlap or completely overlaps with the second pattern. Therefore, through the blank design of the first hollow area and the second hollow area, the transmittance of the superimposed pattern formed by the compensation pattern and the second pattern and the mixed light thereof can be increased. In this way, the optical effect and the uniformity of the appearance pattern can be improved.

[0039] Although the present utility model has been disclosed as above by way of examples, it is not intended to limit the present utility model. Those skilled in the art can make some changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the appended claims.
