Below collocation Fig. 3 is described further the step details of the method for adjustment image display.
Fig. 3 is a kind of process flow diagram adjusting the method for image display of one embodiment of the invention.Please refer to Fig. 3, in the present embodiment, the method for adjustment image display such as can utilize the processor 230 of the electronic installation 100 in Fig. 2 A to perform, but the present invention is not as limit.The method of the adjustment image display of the present embodiment comprises the following steps.First, user can select image model according to actual demand, respectively with the driving intensity of correspondence first group of light source 210 of driving light source module 200 and second group of light source 220 independently.Then, perform step S110, receive image idsplay order.Afterwards, perform step S120, according to image idsplay order, change adjustment first group of light source 210 and second group of light source 220 distinguish corresponding driving intensity, wherein the luminous colour gamut of first group of light source 210 is extensively in the luminous colour gamut of second group of light source 220, and the luminescence efficiency of second group of light source 220 is higher than the luminescence efficiency of first group of light source 210.
In the method that the adjustment image of the present embodiment shows, select the method for image model also to comprise and judge display situation, and determine the luminescence performance that judges corresponding to light source module 210,220 according to display situation, wherein luminous show at least comprise light source module 210,220 output power, luminescence efficiency and luminous colour gamut one of them.Under different image models, processor 230 can determine power ratio according to luminescence performance, power ratio be the output intensity of first group of light source 210 to the ratio of the output intensity of second group of light source 220, and according to power ratio adjust first group of light source 210 and second group of light source 220 distinguish the ratio of corresponding driving intensity.More specifically, display situation can comprise high effective model and wide colour gamut pattern, when being judged as high effective model, reduces power ratio, and when being judged as wide colour gamut pattern, hoisting power ratio.For example, in the present embodiment, different image models can define in advance respectively according to different image function demands, on electronic installation 100, such as carry out its demand for the color saturation of image when photo is browsed higher, and when carrying out audio-visual browsing, then do not need too high color saturation, and can the luminescence efficiency of suitably raising group light source, to avoid too high power attenuation.
Furthermore, as shown in Figure 3, step S120 comprises sub-step S121, S122 and S123.
In the step 120, processor 230 can perform step S121 or S122 according to image idsplay order, close the one of first group of light source 210 and second group of light source 220 and only open the another one of first group of light source 210 and second group of light source 220, such as, close first group of light source 210 and only open second group of light source 220 (as shown in step S121) or close first group of light source 210 and only open second group of light source 220 (as shown in step S122).Or perform step S123, open first group of light source 210 and second group of light source 220 simultaneously, and adjust first group of light source 210 and second group of light source 220 distinguish corresponding driving intensity.In the present embodiment, processor 230 adjust first group of light source 210 and second group of light source 220 the method for corresponding respectively driving intensity be such as the size of current of control flow check through different groups of light sources, so can reach adjustment first group of light source 210 and second group of light source 220 distinguish the effect of corresponding driving intensity.
Fig. 4 is the luminescence efficiency of the light source module of Fig. 2 A, color saturation and the graph of a relation of current ratio flowing through different groups of light sources.Please refer to Fig. 2 A and Fig. 4, for example, the size of current flowing through first group of light source 210 and second group of light source 220 can be enumerated as shown in Table 1.But hereinafter cited data are also not used to limit the present invention, any those skilled in the art with reference to after the present invention, when suitable change can be done to its parameter or setting, precisely because must belong in category of the present invention.
| Size of current (mA) |
[0050]
| First group of light source 210 | 0 | 5 | 10 | 15 | 20 |
| Second group of light source 220 | 20 | 15 | 10 | 5 | 0 |
| Current ratio R | 0 | 0.33 | 0.5 | 3 | Infinitely great |
< table one >
In Table 1, the size of current summation of first group of light source 210 and second group of light source 220, be such as 20 milliamperes (mA), but it is different from the size of current of second group of light source 220 owing to flowing through first group of light source 210, therefore light source module 200 also can have different luminescence efficiencys, and also can have different color saturations.Please refer to table one and Fig. 4, in the present embodiment, current ratio R is defined as the ratio of the size of current flowing through first group of light source 210 and the size of current flowing through second group of light source 220, in other words, when current ratio is larger, the size of current that representative flows through first group of light source 210 can be greater than the size of current flowing through second group of light source 220, therefore the luminescence efficiency of light source module 200 better (as Fig. 4 the solid line trend that illustrates), but color saturation will decline (as Fig. 4 the dotted line trend that illustrates).Otherwise, when current ratio more hour, the luminescence efficiency of light source module 200 is poor, but can promote color saturation.Thus, user then can carry out the setting of image model according to actual demand, and adjust under different images pattern first group of light source 210 and second group of light source 220 distinguish corresponding driving intensity, with the luminescence efficiency of the display effect and light source module 200 of taking into account image.
Then, please referring again to Fig. 3, perform step S130, according to image idsplay order, change with the gamma curve of light source module 200 display panel 120 that is light source.For example, when the size of current flowing through second group of light source 220 is larger, electronic installation 100 can be made to provide the image frame of high color saturation.In this mode, the gamma curve of the image frame presented for display panel 120 by processor 230 adjusts, and carry out corresponding picture signal process (Image Signal Process), can be returned in the colour gamut of memory color (Memory Color) of system definition to make the colour of skin in people's cognition or particular color.So, the pixel color of image can be made to reach the effect improving saturation degree, the colour of skin in people's cognition or particular color also can be made to keep natural complexion simultaneously.
In addition, though the first white light emitting diode 211 of previous embodiment and the second white light emitting diode 221 are to be encapsulated in for illustrate in different light-emitting components, the present invention is not as limit.In another embodiment, the first white light emitting diode 211 and the second white light emitting diode 221 also can be packaged in same light-emitting component LE (as shown in Figure 5), are explained orally further by collocation Fig. 5 below.
