The specific embodiment
Below will clearly demonstrate spirit of the present invention with accompanying drawing and detailed description, as the person skilled in the art after understanding embodiments of the invention, when can be by the technology of teachings of the present invention, change and modification, it does not break away from spirit of the present invention and scope.
See also Fig. 1, Fig. 1 is a sorting gamut of chromaticities district figure of light emitting diode.The light emitting diode that arbitrary batch is given birth to can be distinguished the gamut of chromaticities district (for example A-I gamut of chromaticities district) of multiple grade after the sorting of chromatic value specification.Generally speaking, and the gamut of chromaticities district in centre position (E gamut of chromaticities district for example, Cx is about 0.3-0.4, Cy is about 0.3-0.4) and be an average chrominance scope, the luminescent chromaticity that this average chrominance scope is presented is essentially white light.To belong to cool colour be colourity to the gamut of chromaticities district in centre position (for example E gamut of chromaticities district) luminescent chromaticity of being presented towards the gamut of chromaticities district (for example E-A gamut of chromaticities district) of a direction Q1 institute warp thus, the luminescent chromaticity that it changed transfers Bai Pianlan (cold) light (for example D gamut of chromaticities district), light blue (cold) light (for example C, B gamut of chromaticities district) to gradually by white light (for example E gamut of chromaticities district), finally transfer indigo plant (cold) light (A gamut of chromaticities district for example to, Cx is about 0.1-0.2, and Cy is about 0.05-0.1); Otherwise, to belong to warm colour be colourity to the luminescent chromaticity that presented towards the gamut of chromaticities district (for example E-I gamut of chromaticities district) of a direction Q2 institute warp of the gamut of chromaticities district in centre position thus, the luminescent chromaticity that it changed transfers Bai Pianhong (warming up) light (for example F gamut of chromaticities district), pale red (warming up) light (for example G, H gamut of chromaticities district) to gradually by white light (for example E gamut of chromaticities district), finally transfer red (warming up) light (I gamut of chromaticities district for example to, Cx is about 0.55-0.65, and Cy is about 0.3-0.4).
Moreover, the gamut of chromaticities district in above-mentioned centre position, thus the gamut of chromaticities district in centre position towards the gamut of chromaticities district of a direction Q1 institute warp and thus the gamut of chromaticities district in centre position be general general introduction towards the gamut of chromaticities district of a direction Q2 institute warp.If segment the purposes of display floater again, then above-mentioned gamut of chromaticities district will change.For example: when display floater be large scale (for example: in the time of TV etc.), (E gamut of chromaticities district for example, the gamut of chromaticities district in centre position, Cx is about 0.25-0.27, Cy is about 0.22-0.24), and when display floater is small-medium size (for example: the screen of mobile computer, mobile phone screen or the like), the gamut of chromaticities district in centre position (E gamut of chromaticities district for example, Cx is about 0.28-0.31, Cy is about 0.28-0.30).Therefore, the display floater purposes is different with size, then thus the gamut of chromaticities district in centre position towards a direction Q1 and Q2 respectively the gamut of chromaticities district of warp will change respectively, for example: (Cx in A gamut of chromaticities district is about 0.22-0.24 towards the gamut of chromaticities district of a direction Q1 institute warp, Cy is about 0.19-0.21), and towards the gamut of chromaticities district (Cx in I gamut of chromaticities district is about 0.27-0.29, and Cy is about 0.26-0.28) of a direction Q2 institute warp.
But inference like this, if with the gamut of chromaticities district (for example E gamut of chromaticities district) in centre position be intermediate point, both sides, the gamut of chromaticities district in centre position (for example E gamut of chromaticities district) the luminescent chromaticity of symmetrical gamut of chromaticities district (for example A gamut of chromaticities district and I gamut of chromaticities district) representative can be mixed into the white light in the gamut of chromaticities district (for example E gamut of chromaticities district) that is similar to the centre position in fact mutually.
See also Fig. 2 and Fig. 3 A.Fig. 2 is the schematic diagram of display of the present invention in an embodiment.Fig. 3 A is that backlight module of the present invention is in the schematic diagram of an embodiment.
The present invention is a kind of electrooptical device, display 100 and backlight module 300.Display 100 comprises a backlight module 300 and a display floater 200.
See also Fig. 3 A and Fig. 3 B.Fig. 3 B is the arrangement mode schematic diagram of the light-emitting component 530 of Fig. 3 A in an embodiment.
These light-emitting components 530 all are distributed in the above-mentioned multiple gamut of chromaticities district, and be arranged on first circuit substrate 510 and the second circuit substrate 520 with mixing, the luminescent chromaticity that makes all light-emitting components 530 on the circuit substrate 510 of winning presents the white light in the above-mentioned average chrominance scope after mixing, the luminescent chromaticity of all light-emitting components 530 on the second circuit substrate 520 presents the white light in the above-mentioned average chrominance scope after mixing, simultaneously, be arranged on first circuit substrate 510 and the second circuit substrate 520 in these light-emitting components 530 and the luminescent chromaticity of several contiguous light-emitting components 530 also presents above-mentioned average chrominance scope in the same manner mutually white light.
Therefore, because be positioned in these light-emitting components 530 on first circuit substrate 510 and the second circuit substrate 520 and the luminescent chromaticity of the light-emitting component 530 that is close to mutually identical in fact with other light-emitting component 530 on first circuit substrate 510 and the second circuit substrate 520 through mixed luminescent chromaticity, so, light emitting module 500 just can present uniform white light on equal finish 400, avoid producing light and mix uneven situation, to improve the light quality that of backlight module 300.Moreover present embodiment can also 55 o'clock following display floaters 200 be an example.Therefore, when adopting a side incident of equal finish 400, light emitting module 500 is the long limits that are arranged at equal finish 400.When above, light emitting module 500 also optionally is arranged at the minor face of equal finish 400 when display floater is 55.
Below will expose several embodiment of the arrangement mode of light-emitting component 530, further to illustrate invention spirit of the present invention according to foregoing description.Yet these arrangement modes only are explanation in specification example hereinafter, and the present invention is not limited to this, and the designer can select suitable arrangement mode according to each above-mentioned principle.
See also Fig. 1 and Fig. 3 B again.In the first embodiment of the present invention, these light-emitting components 530 can be divided into a plurality of first light emitting diodes 531 and a plurality of second light emitting diode 532.Each first light emitting diode 531 all has one first luminescent chromaticity, and (for example cool colour is a colourity, preferably be white colder colour system colourity), each second light emitting diode 532 all has second luminescent chromaticity, and (for example warm colour is a colourity, be colourity preferably for white warm colour partially), first luminescent chromaticity and second luminescent chromaticity are the luminescent chromaticity of symmetrical gamut of chromaticities district, the both sides, gamut of chromaticities district (for example E gamut of chromaticities district) in centre position (for example A gamut of chromaticities district and I gamut of chromaticities district) representative.
Wherein Yi Bufen first light emitting diode 531 and second light emitting diode 532 are arranged on first circuit substrate 510 with being staggered in turn one to one each other; First light emitting diode 531 of remainder and second light emitting diode 532 are arranged on the second circuit substrate 520 with being staggered in turn one to one each other, and shown in the frame of broken lines of Fig. 3 B, a light-emitting component of the most adjacent second circuit substrate 520 is first light emitting diode 531 on first circuit substrate 510, and a light-emitting component of the most adjacent first circuit substrate 510 is second light emitting diode 532 on the second circuit substrate 520.
The gamut of chromaticities district under second luminescent chromaticity that is different in essence, gamut of chromaticities district under first luminescent chromaticity, and the gamut of chromaticities district in above-mentioned centre position (for example E gamut of chromaticities district) is between the gamut of chromaticities district and the gamut of chromaticities district under second luminescent chromaticity under first luminescent chromaticity, and, first luminescent chromaticity and the white light that presents the gamut of chromaticities district in above-mentioned centre position after second luminescent chromaticity mixes mutually.
For example, when first luminescent chromaticity belongs to the gamut of chromaticities district (for example A gamut of chromaticities district) of the direction Q1 least significant end of Fig. 1 and presents indigo plant (cold) light time, second luminescent chromaticity then belongs to the gamut of chromaticities district (for example I gamut of chromaticities district) of the direction Q2 least significant end of Fig. 1 and presents red (warming up) light, therefore, shown in the frame of broken lines of Fig. 3 B, present white light on first circuit substrate 510 near first light emitting diode 531 of second circuit substrate 520 can mix mutually with adjacent second light emitting diode 532 on first circuit substrate 510, also can with second circuit substrate 520 on adjacent 532 mutual mixing of second light emitting diode and present white light.
Again for example, when on first luminescent chromaticity belongs to the direction Q1 of Fig. 1, presenting the gamut of chromaticities district (for example D gamut of chromaticities district) of Bai Pianlan (cold) light, second luminescent chromaticity then belongs to the gamut of chromaticities district (for example F gamut of chromaticities district) that presents Bai Pianhong (warming up) light on the direction Q2 of Fig. 1, therefore, shown in the frame of broken lines of Fig. 3 B, on first circuit substrate 510 near first light emitting diode 531 of second circuit substrate 520 can with first circuit substrate 510 on adjacent second light emitting diode 532 mix mutually and present white light, also can with second circuit substrate 520 on adjacent 532 mutual mixing of second light emitting diode and present white light.
See also Fig. 1 and Fig. 3 C.Fig. 3 C is the arrangement mode schematic diagram of another embodiment of the light-emitting component of Fig. 3 A.In the above-described embodiment, these first light emitting diodes 531 also can change into each other with these second light emitting diodes 532, and two pairs two ground are arranged on first circuit substrate 510 and the second circuit substrate 520 with being staggered in turn, and shown in the frame of broken lines of Fig. 3 C, two light-emitting components of the most adjacent second circuit substrate 520 are second light emitting diode 532 on first circuit substrate 510, and two light-emitting components of the most adjacent first circuit substrate 510 are first light emitting diode 531 on the second circuit substrate 520.Therefore, on first circuit substrate 510 near two second light emitting diodes 532 of second circuit substrate 520 can with first circuit substrate 510 on adjacent two first light emitting diodes 531 mix mutually and present white light, also can with second circuit substrate 520 on adjacent 531 mutual mixing of two first light emitting diodes and present white light.
See also Fig. 1 and Fig. 3 D.Fig. 3 D is the arrangement mode schematic diagram of another embodiment of the light-emitting component of Fig. 3 A.In the second embodiment of the present invention, these light-emitting components can be divided into a plurality of the 3rd light emitting diodes 533, a plurality of the 4th light emitting diode 534 and a plurality of the 5th light emitting diode 535.Each the 3rd light emitting diode 533 all has one the 3rd luminescent chromaticity.Each the 4th light emitting diode 534 all has the 4th luminescent chromaticity.Each the 5th light emitting diode 535 all has the 5th luminescent chromaticity.
The 3rd light emitting diode 533, the 4th light emitting diode 534 and the 5th light emitting diode 535 are arranged in turn in order and are arranged on first circuit substrate 510 and the second circuit substrate 520, and the 3rd light emitting diode 533, the order that the 4th light emitting diode 534 and the 5th light emitting diode 535 are arranged in regular turn in turn can be connected on adjacent first circuit substrate 510 and second circuit substrate 520, that is to say, shown in the frame of broken lines of Fig. 3 D, be positioned on first circuit substrate 510 and the second circuit substrate 520 in these light-emitting components and three contiguous mutually light-emitting components are the 3rd light emitting diode 533, the 4th light emitting diode 534 and the 5th light emitting diode 535.
For example a light-emitting component of the most adjacent second circuit substrate 520 is the 3rd light emitting diode 533 on first circuit substrate 510, and two light-emitting components of the most adjacent first circuit substrate 510 just are the 4th light emitting diode 534 and the 5th light emitting diode 535 in regular turn on the second circuit substrate 520.Perhaps, for example a light-emitting component of the most adjacent second circuit substrate 520 is the 4th light emitting diode 534 on first circuit substrate 510, and two light-emitting components of the most adjacent first circuit substrate 510 just are the 5th light emitting diode 535 and the 3rd light emitting diode 533 in regular turn on the second circuit substrate 520.
Above-mentioned the 3rd luminescent chromaticity can be for example for cool colour be colourity, above-mentioned the 4th luminescent chromaticity can be for example for warm colour is that colourity and above-mentioned the 5th luminescent chromaticity can be for example for white light colourities or for cool colour is that colourity and warm colour are the colourity alternative, make the 3rd luminescent chromaticity, the 4th luminescent chromaticity and can present the white light in the gamut of chromaticities district in above-mentioned centre position after the 5th luminescent chromaticity mixes mutually.Therefore, on first circuit substrate 510 near the light-emitting component (for example the 3rd light emitting diode 533) of second circuit substrate 520 can with first circuit substrate 510 on adjacent two light-emitting components (the 4th light emitting diode 534 and the 5th light emitting diode 535) mix mutually and present white light, also can with second circuit substrate 520 on adjacent two light-emitting components (the 4th light emitting diode 534 and the 5th light emitting diode 535) mix mutually and present white light.
For example, when the 3rd luminescent chromaticity belongs to the gamut of chromaticities district (for example A gamut of chromaticities district) of the direction Q1 least significant end of Fig. 1 and presents indigo plant (cold) light, and the 4th luminescent chromaticity then belong to the gamut of chromaticities district (for example I gamut of chromaticities district) of the direction Q2 least significant end of Fig. 1 and present red (warming up) light time, then the 5th luminescent chromaticity then can belong to the gamut of chromaticities district (for example E gamut of chromaticities district) in the centre position of Fig. 1 and present white light, therefore, the 3rd light emitting diode 533, the 4th light emitting diode 534 and the 5th light emitting diode 535 just can mix the back mutually and present white light.
For example working as the 3rd luminescent chromaticity again belongs to the gamut of chromaticities district (for example A gamut of chromaticities district) of the direction Q1 least significant end of Fig. 1 and presents indigo plant (cold) light time, the 4th luminescent chromaticity belongs to the gamut of chromaticities district (for example F gamut of chromaticities district) that presents Bai Pianhong (warming up) light on the direction Q2 of Fig. 1, and the 5th luminescent chromaticity belong to the gamut of chromaticities district (for example H gamut of chromaticities district) that presents pale red (warming up) light on the direction Q2 of Fig. 1, therefore, the 3rd light emitting diode 533, the 4th light emitting diode 534 and the 5th light emitting diode 535 just can mix the back mutually and present white light.
See also Fig. 1 and Fig. 3 E.Fig. 3 E is the arrangement mode schematic diagram of another embodiment of the light-emitting component of Fig. 3 A.In the third embodiment of the present invention, these light-emitting components can be divided into a plurality of first light emitting diodes 531 and a plurality of second light emitting diode 532 and at least two the 6th light emitting diodes 536.Each first light emitting diode, 531 equal tool first luminescent chromaticities (for example cool colour is a colourity), above-mentioned each second light emitting diode, 532 equal tool second luminescent chromaticities (for example warm colour is a colourity).The 6th light emitting diode 536 equal tool white light colourities.Wherein Yi Bufen first light emitting diode 531 and second light emitting diode 532 are arranged on first circuit substrate 510 with being staggered in turn one to one each other; First light emitting diode 531 of remainder and second light emitting diode 532 are arranged on the second circuit substrate 520 with being staggered in turn one to one each other, but shown in the frame of broken lines of Fig. 3 E, on first circuit substrate 510 and the second circuit substrate 520 and two contiguous mutually light-emitting components then be the 6th light emitting diode 536.
For example, when first luminescent chromaticity belongs to the gamut of chromaticities district (for example A gamut of chromaticities district) of the direction Q1 least significant end of Fig. 1 and presents indigo plant (cold) light time, second luminescent chromaticity then belongs to the gamut of chromaticities district (for example I gamut of chromaticities district) of the direction Q2 least significant end of Fig. 1 and presents red (warming up) light.Because the 6th light emitting diode 536 has white light colourity, therefore all first light emitting diodes 531, second light emitting diode 532 present white light with 536 mutual mixing of the 6th light emitting diode on first circuit substrate 510.All first light emitting diodes 531, second light emitting diode 532 present white light with 536 mutual mixing of the 6th light emitting diode on the second circuit substrate 520.
