The backlight source component consists of a lattice light conducting plate and light emitting diodes; the lower plane of the lattice light conducting plate is glued with a reflecting sheet and the upper plane is glued with a light pervious dodging sheet; the front and back sides and the left, light ends of the lattice light conducting plate are all provided with light sweeping strip; the left and the right sides are both correspondingly provided with connection plates; the two connection plates are respectively fixed light emitting diodes; the two sides of the light conducting plate are both provided with arc notches which are corresponding to the light emitting diodes and the light emitting diodes stretch into the arc notches. The utility model has the advantages of even radiation, high brightness and service life, low cost and error rate.
Description
Technical field
The utility model relates to the motorcycle instrument technical field of liquid crystal display, particularly a kind of motorcycle instrument LCDs that adopts the LED-backlit source.
Background technology
In the lcd technology of using on motorcycle instrument, conventional art is ordinary light source to be set as back illumination at the liquid crystal display top; At present, advanced lcd technology is the EL cold light film to be set as back-illumination source below liquid crystal display.Conventional art liquid crystal display back-illumination source power consumption height, the backlight part easily breaks down, and its back-illumination source also has the shortcoming that can't illuminate whole screen equably owing to be line source all.With the EL cold light source as liquid crystal screen back light source, be have luminous evenly soft, anti-seismic performance is good, advantages such as no intensification phenomenon, but the EL cold light source is an alternating current die mould device, needs higher alternating voltage to drive during work, in order to convert the DC voltage on the motorcycle to working volts alternating current, need to add the voltage inverter circuit, be furnished with transformer.Therefore, its backlight departmental cost and failure rate are all higher, and brightness and life-span are also lower.
Summary of the invention
The utility model provides a kind of motorcycle instrument LCDs that adopts the LED-backlit source for solving the problem that above-mentioned liquid crystal screen back light source exists, and makes all higher, cost of its brightness and life-span and failure rate all lower.
A kind of motorcycle instrument LCDs described in the utility model comprises liquid crystal board and is located at backlight device below the liquid crystal board that it is characterized in that: described backlight device is made up of dot matrix light guide plate and LED light emitting diode; Described dot matrix light guide plate lower plane posts reflecting piece, the even mating plate of printing opacity is posted on last plane, two sides, front and back and left and right sides edges at two ends peripheric surface are equipped with the band that is in the light, the all corresponding terminal block that is provided with of left and right sides face, be fixed with the LED light emitting diode in two terminal blocks respectively, and the light guide plate left and right sides is equipped with the arc-shaped notch corresponding with the LED light emitting diode, and the LED light emitting diode is stretched in this arc-shaped notch.
Described reflecting piece can be iridescent paper, and even mating plate can be the dry sanding paper of printing opacity, and the band that is in the light can be aluminum foil and adhesive tape.
The utility model is owing to adopted the LED-backlit source device of being made up of dot matrix light guide plate and LED light emitting diode, and LED brightness and life-span are all high, and provides area source by the dot matrix light guide plate for liquid crystal display, and luminous evenly soft, become clear; Whole LED backlight device cost and failure rate are all lower.Therefore, the utlity model has advantages such as all higher, cost of brightness and life-span and failure rate be all lower.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is for dot matrix light guide plate among Fig. 1 and the reflecting piece of joining, even mating plate, the band synoptic diagram is in the light.
Embodiment
As shown in Figure 1 and Figure 2, a kind of motorcycle instrument LCDs comprises liquid crystal board 5 and is located at backlight device below the liquid crystal board 5 that described backlight device is made up of dot matrix light guide plate 4 and LED light emitting diode 3; Described dot matrix light guide plate 4 lower planes post reflecting piece 4f, the even mating plate 4b of printing opacity is posted on last plane, the two sides, front and back are provided be in the light band 4a, 4d, left and right sides edges at two ends peripheric surface is equipped be in the light band 4c, the 4e that can surround circle, the all corresponding terminal block 2 that is provided with of left and right sides face, be provided with wiring perforation 1 in the terminal block 2, be fixed with two LED light emitting diodes in each terminal block respectively, the light guide plate left and right sides is respectively equipped with and corresponding two arc-shaped notch 6 of LED light emitting diode, and each LED light emitting diode 3 is all stretched in corresponding arc-shaped notch.
Described band 4c, the 4e of being in the light is aluminum foil and adhesive tape, and sticks on dot matrix light guide plate 4 left and right sides edges at two ends peripheric surfaces; And reflecting piece 4f is an iridescent paper, and even mating plate 4b is the dry sanding paper of printing opacity, and reflecting piece 4f and two ends, the even mating plate 4b left and right sides all are attached on be in the light band 4c, the 4e.
Described dot matrix light guide plate 4 is printed to the site of regular distribution for adopting the printing net-point technology on the light guide plate face, make backlight become area source, and sends evenly soft, bright light.
It is light source that the utility model has adopted all higher LED light emitting diode of brightness and life-span, and is combined as liquid crystal display with the dot matrix light guide plate area source is provided, and it is luminous evenly soft, bright; Whole LED backlight device cost and failure rate are all lower, brightness and life-span are all higher.
Claims (2)
