Summary of the invention
The objective of the invention is to overcome above-mentioned existing touch-type remote controller and adopt a large amount of light emitting diodes just can reach the shortcoming of purpose backlight, a kind of backlight device of touch remote controller is provided.
The present invention solves its technical problem, the technical scheme that adopts is, backlight device of touch remote controller, comprise pcb board, described pcb board front is provided with at least one touch-type key area, described touch-type key area with cells arranged in matrix on pcb board, it is characterized in that, also comprise at least one leaded light groove, at least two light emitting diodes, each touch-type key area is provided with at least one light hole, the two ends of described each leaded light groove respectively are provided with a light emitting diode, and the leaded light groove is arranged on row or delegation touch-type key area is corresponding with the light hole of these row or this row touch-type key area down.
Concrete, also comprising title stock, described title stock is arranged on the touch-type key area corresponding with the light hole of this touch-type key area.
Further, described each touch-type key area is provided with two light holes, and it is corresponding with two light holes of these row or this row touch-type key area respectively that each row or each row touch-type key area are arranged with two leaded light grooves.
Concrete, two light emitting diodes at described leaded light groove two ends adopt red light-emitting diode, and two light emitting diodes at another leaded light groove two ends adopt blue light-emitting diode.
The invention has the beneficial effects as follows, the leaded light groove is joined in the touch-type remote controller, adopt a small amount of light emitting diode can reach purpose backlight, save cost, add title stock, on title stock, set and the corresponding indicating graphic of this touch key-press, can make the user get information about the function of this touch key-press, two light holes are set on each touch-type key area, two respectively corresponding two leaded light grooves of light hole, two leaded light grooves adopt the light emitting diode of different colours that light source is provided, promptly adopt two leaded light grooves that per two light holes difference on the touch-type key area of these row or delegation is come, promptly have two relatively independent leaded light grooves under a touch-type key area, then can make the touch-type button behind multiplexing functions, also still make things convenient for the user to observe use.
Description of drawings
Fig. 1 is the schematic diagram of embodiment;
Wherein, 1 is pcb board, and 2 is the touch-type key area, and 3 is light hole, and 4 is the first leaded light groove, and 5 is the second leaded light groove, and 6 is title stock, and X, O represent two kinds of function indicating graphics being provided with on the title stock.
The specific embodiment
Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.
The invention provides a kind of backlight device of touch remote controller, it comprises pcb board 1, pcb board 1 front is provided with at least one touch-type key area 2, these touch-type key areas 2 with cells arranged in matrix on pcb board 1, each touch-type key area 2 is provided with at least one light hole 3, also comprise at least one leaded light groove and at least two light emitting diodes, wherein the two ends of each leaded light groove respectively are provided with a light emitting diode, and the leaded light groove is arranged on row or delegation touch-type key area 2 times is corresponding with the light hole 3 of these row or this capable touch-type key area 2.
Embodiment
Each touch-type key area 2 of this example is provided with two light holes 3, it is corresponding with two light holes 3 of these row or this row touch-type key area 2 respectively that each row or each row touch-type key area 2 are arranged with two leaded light grooves, with four touch-type key areas of row 2 wherein is example, its schematic diagram such as Fig. 1.
At first in these four touch-type key areas 2, two light holes 3 arranging about being provided with respectively on each touch-type key area 2, then possess eight light holes 3 in this row touch-type key area 2, form two row light holes 3, four light holes 3 of every row, two leaded light grooves under this row touch-type key area are named with the first leaded light groove 4 and the second leaded light groove 5 respectively, then the first leaded light groove 4 is corresponding with a row light hole 3, the second leaded light groove 5 is corresponding with another row light hole 3, the light emitting diode at the first leaded light groove, 4 two ends adopts red light-emitting diode, the light emitting diode at the second leaded light groove, 5 two ends adopts blue light-emitting diode, on each touch-type key area 2, title stock 6 is set again, title stock 6 and two light hole 3 corresponding places set respectively and the corresponding two kinds of indicating graphics of the touch key-press of this multiplexing functions, two kinds of function indicating graphics promptly are set on title stock 6, and (diagram is with X, O represents), each function indicating graphic is corresponding with a light hole, then have two groups of function indicating graphics on this row touch-type key area, and two groups of respectively corresponding leaded light grooves of function indicating graphic, promptly two groups of function indicating graphics are respectively by different backlight indicating, this moment is if the touch-type button of this touch-type remote controller possesses multiplexing functions, then when the user selects wherein one group of function key, the lumination of light emitting diode at the first leaded light groove 4 or the second leaded light groove, 5 two ends, be that one group of function indicating graphic and light hole 3 carry out backlight, another group function indicating graphic and light hole 3 are still not backlight, the user can be had the function of this touch-type button by function indicating graphic backlight get information about, make things convenient for the user that household electrical appliance are operated.
