Embodiment
Now further understand and understanding for the auditor is had technical characterictic of the present invention and the effect reached,, the display device according to preferred embodiment of the present invention is described hereinafter with reference to relevant drawings.
See also Fig. 1, be the synoptic diagram of the light-emitting device of one embodiment of the invention.Among the figure, light-emitting device 12 comprises sign 121, one a power supply module 122 and an illuminating module 123, and is applicable to the display device 11 with a backboard 111 and a module 112 backlight.Wherein, sign 121 is arranged on the backboard 111, and identifies 121 and can be an at least one character or a pattern.Power supply module 122 is arranged between backboard 111 and the module backlight 112, is used to absorb a backlight 1121 of module 112 backlight, to produce a power supply.One illuminating module 123 is arranged at sign 121 and 122 of power supply modules, receives power supply and produces a light source, identifies 121 to be projected to.
See also Fig. 2, be the synoptic diagram of sign of the present invention.As shown in the figure, a sign is set 121 on backboard 111, and identifies 121 and can be at least one character or at least one pattern, and this figure will to identify 121 be example with the character.
See also Fig. 3, be the synoptic diagram of light-emitting device of the present invention.As shown in the figure, light-emitting device 12 is applicable to display device 11.Wherein, display device 11 has a module 112 backlight, and light-emitting device 12 comprises sign 121, one a power supply module 122 and an illuminating module 123.Module 112 backlight provides a backlight 1121.Power supply module 122 comprises a light collecting plate 31 and a photoelectric cell 32, and light collecting plate 31 is in order to absorbing backlight 1121, and backlight 1121 is converted to a power supply 33, and 32 on photoelectric cell is in order to store power supply 33.Illuminating module 123 comprises a plurality of light emitting diodes 34 and a control module 35, and electrically connects 36 in power supply module 122, so that a power supply 33 of illuminating module 123 to be provided.After control module 35 receives power supply 33, give those light emitting diodes 34 by control module 35 power supplies, produce a light source 37 to be projected to sign 121.
