[0028] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic diagram of a first light L1 of a light emitting panel 10 passing through an optical film 20 according to an embodiment of the present invention. Figure 2FIG. 1 is a schematic diagram showing the positions of the first coordinate (x1, y1) and the second coordinate (x2, y2) on the CIE1931 color space chromaticity diagram according to an embodiment of the present invention. Figure 1 As shown, the present invention provides an electronic device 1, which includes a light-emitting panel 10 and an optical film 20. The optical film 20 is disposed on the light-emitting panel 10. The light-emitting panel 10 emits a first light L1. The first light L1 has at least one corresponding position DP1 in the CIE 1931 color space (see Figure 2 The modulated color point (not otherwise labeled) of the optical film 20 has at least one corresponding position DP2 in the CIE 1931 color space (see Figure 2 ). In the CIE 1931 color space, the at least one corresponding position DP1 of the first light L1 has a corresponding first coordinate (x1, y1), the at least one corresponding position DP2 of the modulation color point has a corresponding second coordinate (x2, y2), and the first coordinate (x1, y1) and the second coordinate (x2, y2) satisfy the following relationship relative to the equation y(x)=-2.48x^2+2.52x-0.22: when (y1-y(x1))>0, (y2-y(x2))<0, or when (y1-y(x1))<0, (y2-y(x2))>0; 0.1≤x1≤0.6; and 0.1≤x2≤0.6.

[0029] Figure 1 In order to illustrate the first light L1, a gap is arranged between the light emitting panel 10 and the optical film 20. However, in fact, the light emitting panel 10 and the optical film 20 can be arranged close to each other, or there is only a small gap between them, or there is an adhesive layer (such as Fig. 8A The adhesive layer 30) is connected, but the present invention is not limited to this.

[0030] The electronic device 1 may be, for example, a self-luminous electronic device or a non-self-luminous electronic device. When the electronic device 1 is a self-luminous electronic device, the light-emitting panel 10 may be, but is not limited to, a micro-millimeter light-emitting diode panel or an organic light-emitting diode panel. When the electronic device 1 is a non-self-luminous electronic device, the light-emitting panel 10 may be a liquid crystal panel, in which case the electronic device 1 may further include a backlight module (not shown). For other details about the light-emitting panel 10, please refer to Fig. 8A , Figure 8B Related instructions.

[0031] The optical film 20 may be a transparent or translucent decorative film layer, for example, a decorative film layer, and may selectively include colors, patterns, lines, other suitable patterns, or a combination thereof, but not limited thereto. The transparency, color, and pattern at different positions on the optical film 20 may be the same or different. Therefore, different regions of the optical film 20 may be regarded as having respective corresponding modulation color points. Therefore, the optical film 20 has a set of multiple modulation color points, and each modulation color point has a corresponding position or multiple corresponding positions in the CIE 1931 color space, for example Figure 2 In another embodiment, the modulated color point measured at the geometric center of the optical film 20 may be regarded as the modulated color point of the optical film 20, but the present invention is not limited thereto. In another embodiment, the modulated color points measured at multiple locations of the optical film 20 may be averaged and regarded as the modulated color point of the optical film 20, but the present invention is not limited thereto. The aforementioned modulated color point has a corresponding second coordinate at a corresponding position or at least one of multiple corresponding positions in the CIE 1931 color space, for example Figure 2 The second coordinate (x2, y2) in the image. For example, the aforementioned modulated color point can be measured by a film color point measurement method to obtain the light transmittance chromaticity coordinates of the aforementioned optical film 20: This measurement method uses a reference light source to illuminate any point on the optical film 20, and the reference light emitted by the reference light source has an intensity value at each wavelength, thereby forming a first spectral intensity distribution. After penetrating the optical film 20, the reference light will emit a transmitted light, and the transmitted light has another intensity value at each wavelength, thereby forming a second spectral intensity distribution. The second spectral intensity distribution of the transmitted light is divided by the first spectral intensity distribution of the reference light (that is, starting from the shortest wavelength, and gradually calculating the intensity ratio of the transmitted light and the reference light at the same wavelength until the longest wavelength), to obtain a third spectral intensity distribution. Finally, based on the third spectral intensity distribution, the modulated color point of the optical film 20 is calculated. For other details about the optical film 20, please refer to Fig. 8A , Figure 8B Related instructions.

[0032] Figure 1 In the embodiment, the light emitting panel 10 emits a first light L1, and the first light L1 passes through the optical film 20 to emit a second light L2. In other words, the first light L1 of the light emitting panel 10 is affected by the modulation color point of the optical film 20 and is transformed from the first light L1 to the second light L2. In this embodiment, the second light L2 is the light emitted by the light emitting panel 10 (such as the first light L1) and is adjusted after passing through the optical film 20, that is, the light emitted by the electronic device 1. The electronic device 1 has a normal direction N, and the light emitting panel 10 has a light emitting surface 11. The normal direction N of the electronic device 1 is perpendicular to the light emitting surface 11 of the light emitting panel 10.

[0033] Figure 2Among them, the CIE 1931 color space chromaticity diagram includes a color block CB in the shape of a horseshoe, Figure 2 Only the outline of the color block CB is shown in it without presenting colors. However, it should be understood that the color block CB represents all colors visible to the naked eye. For example, the boundary point BP1 represents a greenish color, the boundary point BP2 represents a bluish color, and the boundary point BP3 represents a reddish color. The numbers around the color block CB range from 380 to 700, representing the wavelengths of visible light in nanometers (nm). The curve CV1 is the blackbody color temperature curve, which can also be called the absolute color temperature curve. The short straight lines intersecting with the curve CV1 are the sets of points representing the same color temperature. For example, the straight line PT1 represents the set of points with a color temperature of 10000K, and the straight line PT2 represents the set of points with a color temperature of 6000K, and so on.

[0034] The curve CV2 represents the equation y(x) = -2.48x^2 + 2.52x - 0.22. The curve CV2 is an analog curve of CV1, but the present invention is not limited thereto. The first light ray L1 emitted by the light-emitting panel 10 has a corresponding position DP1 in the CIE 1931 color space, and the position DP1 has a corresponding first coordinate (x1, y1) in the CIE 1931 color space. The modulated color point of the optical film 20 has a corresponding position DP2 in the CIE 1931 color space, and the position DP2 has a corresponding second coordinate (x2, y2) in the CIE 1931 color space. When the x-coordinate of the curve CV2 is x1, the y-coordinate is y(x1), and when the x-coordinate of the curve CV2 is x2, the y-coordinate is y(x2). Figure 2 Among them, taking y(x1) < y1 and y(x2) > y2 as examples, that is, (y1 - y(x1)) > 0, and (y2 - y(x2)) < 0. In other ways, it can be configured as y(x1) > y1 and y(x2) < y2, that is, (y1 - y(x1)) < 0, and (y2 - y(x2)) > 0. In this way, one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the upper side of the curve CV2, and the other of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the lower side of the curve CV2, so that the first light ray L1 and the modulated color point cooperate with each other in color, and the light emitted by the electronic device 1, such as Figure 1 The second light ray L2 in it, its color can meet the requirements. For example, it can improve the problem of color distortion, or it can provide a color temperature range that is more comfortable for the human eye.

[0035] Please refer to Figure 3 , which is a schematic diagram of the positions of the first coordinate (x1, y1) and the second coordinate (x2, y2) in the CIE 1931 color space chromaticity diagram according to another embodiment of the present invention. The straight line ST1 represents the equation x = W x, where 0.25≤W x ≤0.35. Figure 3 In x1 <W x 、x2>W x As an example, (W x -x1)>0, and (W x -x2)<0, in other modes, it can be configured as x1>W x , x2 <W x , that is (W x -x1)<0, and (W x -x2)>0. Thus, one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the left side of the straight line ST1, and the other of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the right side of the straight line ST1, so that the first light L1 and the modulated color point match each other in color. Figure 3 In the example, the shortest distance between the position DP1 and the straight line ST1 is SG1, which is illustrated as |W x -x1|, the shortest distance between position DP2 and straight line ST1 is SG2, SG2 is illustrated here as |x2-W x |, which can satisfy the following condition: |SG2–SG1|≤0.2, that is, |2W x -x2-x1|≤0.2or|x2+x1-2W x |≤0.2; and 0.5≤|SG1| / |SG2|≤1.5, that is, 0.5≤|W x -x1| / |x2-W x |≤1.5, thus, the distance difference between the first coordinate (x1, y1) and the second coordinate (x2, y2) and the straight line ST1 is small, which can improve the problem of color distortion, or provide a color temperature range that is more comfortable for the human eye.

[0036] Please refer to Figure 4 , which is a schematic diagram of the positions of the first coordinate (x1, y1) and the second coordinate (x2, y2) on the CIE 1931 color space chromaticity diagram according to another embodiment of the present invention. Straight line ST2 represents the equation y=W y , where 0.27≤W y ≤0.37. Figure 4 In the <W y 、y2>W y As an example, (W y -y1)>0, and (W y –y2)<0, in other modes, it can be configured as y1>W y ,y2 <W y , that is (W y -y1)<0, and (Wy -y2)>0. Thus, one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located above the straight line ST2, and the other one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located below the straight line ST2, so that the modulation color points of the first light ray L1 and the optical film 20 match each other in color.

[0037] Figure 5 is a schematic diagram of the positions of the first coordinate (x1, y1) and the second coordinate (x2, y2) in the CIE 1931 chromaticity diagram according to another embodiment of the present invention. The straight line ST3 represents the equation y(x)= -1.824x + 0.9. When the x coordinate of the straight line ST3 is x1, the y coordinate is y(x1), and when the x coordinate of the straight line ST3 is x2, the y coordinate is y(x2). Figure 5 Taking y(x1)>y1, y(x2)<y2 as an example, that is, (y1 - y(x1))<0, and (y2 - y(x2))>0. In addition, 0.25≤x1≤0.35, 0.27≤y1≤0.37, and 0.25≤x2≤0.35, 0.27≤y2≤0.37. In other ways, it can be configured as y(x1)<y1, y(x2)>y2, that is, (y1 - y(x1))>0, and (y2 - y(x2))<0. In addition, 0.25≤x1≤0.35, 0.27≤y1≤0.37, and 0.25≤x2≤0.35, 0.27≤y2≤0.37. Thus, one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located above the straight line ST3, and the other one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located below the straight line ST3, so that the modulation color points of the first light ray L1 and the optical film 20 match each other in color.

[0038] Please refer to Figure 1 and Figure 6 , Figure 6It is a schematic diagram of the position of the third coordinate (x3, y3) on the CIE1931 color space chromaticity diagram according to another embodiment of the present invention. The first light L1 passes through the optical film 20 to emit the second light L2. The second light L2 has at least one corresponding position DP3 in the CIE 1931 color space. At least one corresponding position DP3 of the second light L2 has a corresponding third coordinate (x3, y3) in the CIE 1931 color space. Curve CV3 represents the equation y(x) = -2.48x^2 + 2.52x-0.17, and curve CV4 represents the equation y(x) = -2.62x^2 + 2.52x-0.27. The third coordinate (x3, y3) is located between curve CV3 and curve CV4, and 0.2≤x3≤0.5, or, 0.25≤x3≤0.35. In this way, the light emitted by the electronic device 1, for example Figure 1 The color of the second light L2 in the image may meet the requirements, for example, the problem of color distortion may be improved, or a color temperature range that is more comfortable for the human eye may be provided.

[0039] Please refer to Figure 7 Schematic diagram of the positions of the first coordinate (x1, y1) and the second coordinate (x2, y2) on the CIE 1931 color space chromaticity diagram according to another embodiment of the present invention. The straight line PT2 represents a set of points with a color temperature of 6000K. The first coordinate (x1, y1) corresponds to a first relative color temperature value Wt1 (not shown in the figure), and the second coordinate (x2, y2) corresponds to a second relative color temperature value Wt2. The first relative color temperature value Wt1 and the second relative color temperature value Wt2 satisfy the following relationship: 0.1≤Wt1 / Wt2≤10. The white point corresponds to a reference relative color temperature value Wt, Figure 7 Taking the reference relative color temperature value Wt as 6000K as an example, but not limited thereto, in some embodiments, the reference relative color temperature value Wt of the white point may satisfy the following relationship: 4000K≤Wt≤10000K. Figure 7In the embodiment, the first relative color temperature value Wt1 of the first coordinate (x1, y1) is greater than the reference relative color temperature value Wt of the white point and the second relative color temperature value Wt2 of the second coordinate (x2, y2) is less than the reference relative color temperature value Wt of the white point, that is, when (Wt1-Wt)>0, (Wt2-Wt)<0. In other embodiments, the first relative color temperature value Wt1 of the first coordinate (x1, y1) may be less than the reference relative color temperature value Wt of the white point and the second relative color temperature value Wt2 of the second coordinate (x2, y2) may be greater than the reference relative color temperature value Wt of the white point, that is, when (Wt1-Wt)<0, (Wt2-Wt)>0. Thus, one of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the left side of the straight line representing the reference relative color temperature value Wt (herein, the straight line PT2 representing the color temperature of 6000K is exemplified), and the other of the first coordinate (x1, y1) and the second coordinate (x2, y2) is located on the right side of the straight line representing the reference relative color temperature value Wt (herein, the straight line PT2 representing the color temperature of 6000K is exemplified), so that the first light L1 and the modulated color point are coordinated with each other in color. In some embodiments, the absolute value of the difference between the first relative color temperature value Wt1 and the reference relative color temperature value Wt of the white point may be less than 6000K, that is, |Wt1-Wt|<6000K, and the absolute value of the difference between the second relative color temperature value Wt2 and the reference relative color temperature value Wt of the white point may be less than 6000K, that is, |Wt2-Wt|<6000K. In some embodiments, the absolute value of the difference between the first relative color temperature value Wt1 and the reference relative color temperature value Wt of the white point subtracted from the difference between the second relative color temperature value Wt2 and the reference relative color temperature value Wt of the white point may be less than or equal to 6000K, ie |Wt1+W2-2Wt|≤6000K.

[0040] Figure 7 , the shortest distance between position DP1 and the straight line representing the reference relative color temperature value Wt (herein, the straight line PT2 representing the color temperature of 6000k is exemplified) is DG1, and the shortest distance between position DP2 and the straight line representing the reference relative color temperature value Wt (herein, the straight line PT2 representing the color temperature of 6000k is exemplified) is DG2. The shortest distance DG1 and the shortest distance DG2 satisfy the following relationship: |DG1-DG2|≤0.2. In this way, the distance difference between the first coordinate (x1, y1) and the second coordinate (x2, y2) and the straight line representing the reference relative color temperature value Wt is small. The method for calculating the shortest distance from a point to a straight line is well known in the art and will not be described in detail here. In addition, the shortest distance DG1 and the shortest distance DG2 can also be calculated using a scale to obtain the difference.
