Referring to FIG. 2B to FIG. 2D , the light guide plate 250 has a light incident side LS. The first white light emitting diodes 211 and the second white light emitting diodes 221 are alternately arranged on the flexible circuit board 240 and located on the light incident side LS. (As shown in Figure 2B).

The details of the steps of the method of adjusting the image display will be further described below in conjunction with FIG.

FIG. 3 is a flow chart of a method for adjusting image display according to an embodiment of the invention. Referring to FIG. 3, in the embodiment, the method for adjusting the image display may be performed by, for example, the processor 230 of the electronic device 100 in FIG. 2A, but the invention is not limited thereto. The method for adjusting image display of this embodiment includes the following steps. First, the user can select an image mode according to actual needs, and independently drive a first group of light sources 210 and a second group of light sources 220 of a light source module 200 with corresponding driving strengths. Next, step S110 is executed to receive an image display instruction. Then, in step S120, according to the image display instruction, the driving strengths corresponding to the first group of light sources 210 and the second group of light sources 220 are respectively adjusted, wherein the illuminating color gamut of the first group of light sources 210 is wider than the illuminating color of the second group of light sources 220. In the color gamut, the luminous efficiency of the second group of light sources 220 is higher than the luminous efficiency of the first group of light sources 210.

In the method for adjusting the image display of the embodiment, the method for selecting the image mode may further include determining a display context, and determining, according to the display context, a lighting performance corresponding to the light source module 210, 220, wherein the lighting performance includes at least the light source. One of the output power, the luminous efficiency, and the illuminating color gamut of the modules 210, 220. In different image modes, the processor 230 can determine a power ratio according to the illuminance performance, and the power ratio is a ratio of the output intensity of the first group of light sources 210 to the output intensity of the second group of light sources 220, and adjust the first group according to the power ratio. The ratio of the driving strength of the light source 210 and the second group of light sources 220, respectively. In more detail, the display context can include one The high efficiency mode and the wide color gamut mode reduce the power ratio when judged to be the high efficiency mode, and increase the power ratio when it is judged to be the wide color gamut mode. For example, in this embodiment, different image modes may be separately defined in advance according to different image function requirements. For example, when the photo browsing is performed on the electronic device 100, the color saturation of the image is required to be high. When viewing video and audio, there is no need for too high color saturation, and the luminous efficiency of the group light source can be appropriately increased to avoid excessive power loss.

Further, as shown in FIG. 3, step S120 includes sub-steps S121, S122, and S123.

In step 120, the processor 230 can perform step S121 or S122 according to the image display instruction, and turn off one of the first group of light sources 210 and the second group of light sources 220 to turn on only the first group of light sources 210 and the second group of light sources 220. For example, the first group of light sources 210 are turned off and only the second group of light sources 220 are turned on (as shown in step S121) or the second group of light sources 220 are turned off to turn on only the first group of light sources 210 (as shown in step S122). Or step S123 is performed to simultaneously turn on the first group of light sources 210 and the second group of light sources 220, and adjust the driving intensity ratios of the first group of light sources 210 and the second group of light sources 220 respectively. In this embodiment, the method for the processor 230 to adjust the ratio of the driving intensity corresponding to the first group of the light source 210 and the second group of the light sources 220 is, for example, controlling the current flowing through the different groups of light sources, so that the first group can be adjusted. The effect of the driving intensity corresponding to the light source 210 and the second group of light sources 220, respectively.

4 is a graph showing the relationship between the luminous efficiency, color saturation, and current ratio of different light sources flowing through the light source module of FIG. 2A. Referring to FIG. 2A and FIG. 4 , for example, the current flowing through the first group of light sources 210 and the second group of light sources 220 can be enumerated as shown in Table 1. Shown. However, the data listed below is not intended to limit the invention, and any person having ordinary skill in the art can appropriately change its parameters or settings after referring to the present invention, but it should still fall within the scope of the present invention. Inside.

In Table 1, the sum of currents of the first group of light sources 210 and the second group of light sources 220 is, for example, 20 milliamps (mA), but due to the difference in current flowing through the first group of light sources 210 and the second group of light sources 220, Therefore, the light source module 200 also has different luminous efficiencies and also has different color saturations. Referring to Table 1 and FIG. 4, in the present embodiment, the current ratio R is defined as the ratio of the magnitude of the current flowing through the first group of light sources 210 to the magnitude of the current flowing through the second group of light sources 220. In other words, when the current ratio is higher When large, the current flowing through the first group of light sources 210 is greater than the current flowing through the second group of light sources 220, so the light emitting efficiency of the light source module 200 is worse (as shown by the solid line trend in FIG. 4), However, the color saturation will be better (as shown by the dotted line trend in Figure 4). On the contrary, when the current ratio is smaller, the light-emitting efficiency of the light source module 200 is better, but the color saturation is lowered. In this way, the user can set the image mode according to actual needs, and adjust the driving strengths of the first group of light sources 210 and the second group of light sources 220 in different image modes to take into account the image display effect and the light source. The luminous efficiency of the module 200.

Next, referring again to FIG. 3, step S130 is performed to display according to the image. Instructing to change a gamma curve of the display panel 120 with the light source module 200 as a light source. For example, when the magnitude of the current flowing through the first group of light sources 210 is larger, the electronic device 100 can be made to provide an image picture of high color saturation. In this mode, the gamma curve of the image frame presented by the display panel 120 can be adjusted by the processor 230, and the corresponding image signal processing (Image Signal Process) can be performed to make the perceived skin color or specific. The color can be restored to the color gamut of the system-defined Memory Color. In this way, the pixel color of the image can be improved to achieve saturation, and at the same time, the perceived skin color or specific color can be maintained in a natural appearance.

In addition, the first white light emitting diode 211 and the second white light emitting diode 221 of the foregoing embodiment are illustrated as being packaged in different light emitting elements, but the invention is not limited thereto.

In the present embodiment, the first white light-emitting diode 511 is, for example, a light-emitting diode wafer LC1 on which a phosphor PH is coated. For example, when the light emitting diode chip LC1 is a blue light emitting diode chip, the phosphor body PH may be a red light phosphor and a green light phosphor, and when the light emitting diode chip LC1 is a red light emitting diode. When the wafer and the blue light emitting diode chip are used, the phosphor PH is green light body. On the other hand, the second white light emitting diode 521 comprises a yttrium aluminum garnet YAG and a light emitting diode chip LC2, wherein the light emitting diode chip LC2 is a blue light emitting diode chip, and can be provided with the first white light emitting light The polar body 511 has different illuminating color gamuts and has higher luminous efficiency. . When the light-emitting element LE is applied to the light source module 200, the processor 230 can also adjust the driving strength corresponding to the first group of the light source 210 and the second group of the light sources 220 in different image modes, and the light source mode is The group 200 and the electronic device 100 achieve the previously described functions and advantages, and will not be described herein.

In addition, the first white light-emitting diode 211 of the foregoing embodiment is exemplified by the use of different light-emitting diode chips with different phosphor materials, but the invention is not limited thereto. In other embodiments, the first white light emitting diode 211 can also be used with a light emitting diode chip in combination with different phosphor materials or quantum dot elements. The following will be further explained in conjunction with FIGS. 6A and 6B.

Referring to FIGS. 6A and 6B, the light source modules 600a, 600b are similar to the light source module 200 of FIG. 1, and the differences are as follows.

For example, in the present embodiment, the red light quantum dot element 611Ra and the green light quantum dot element 611G are, for example, quantum dot fluorescent materials, which can be encapsulated in the glass and located in the blue light emitting diode wafer 611B and the light guide plate 250. Between the light side LS. In other words, the red light quantum dot element 611Ra and the green light quantum dot element 611G are located in the blue light. The photodiode wafer 611B is provided on the light transmission path, and can be used to provide white light of a wide color gamut and high color saturation into the display panel 120. In this manner, when the first white light emitting diode 611a is applied to the light source module 600a, the light source module 600a can also adjust the first group of light sources 610a and the second group of light sources 220 by the processor 230 in different image modes.
