Abstract
The utility model provides a double-side LED backlight liquid crystal display, which is provided with two display surfaces with the cost lower than that of two displays. The double-side LED backlight liquid crystal display comprises a first LCD screen on the front side and a second LCD screen positioned on the backside; a first LCD screen light guide device is arranged on the backside of the first LCD screen, and comprises a first light guide plate; a second LCD screen light guide device is arranged on the backside of the second LCD screen, and comprises a second light guide plate; the first light guide plate and the second light guide plate are combined together, and an optical fiber luminous source is embedded therebetween; the optical fiber luminous source is a peeled light penetrable optical fiber core with at least one end connected with an LED luminous source. The backlight of the double-side LED backlight liquid crystal display emits light uniformly, the display effect is stable, and the heat dissipation of LEDs positioned at the two ends is convenient to realize by installing a radiator, thereby ensuring a simple structure of the whole double-side display; the volume of the display can be made small , thereby having low cost.
Description
Technical field
The utility model relates to a kind of LCD of LED-backlit.
Background technology
LCD can only be seen one side usually.If want to allow the equal display image of front and back direction of LCD, then common way is that two LCD are settled back-to-back.This mode widespread use on a lot of trains of settling LCD back-to-back as China.
The mode of above-mentioned double-sided display needs two LCD, and its shortcoming is the cost height.
The utility model content
Technical problem to be solved in the utility model is: a kind of dual surface LED backlight liquid crystal display is provided, and two display surfaces of this displaying appliance, and cost is lower than two displays.
In order to solve the problems of the technologies described above, the utility model proposes a kind of dual surface LED backlight liquid crystal display, this display comprises the first positive liquid crystal display and is positioned at second liquid crystal display at the back side;
Be provided with the first liquid crystal display guiding device in the first liquid crystal display back, the first liquid crystal display guiding device comprises first light guide plate;
Be provided with the second liquid crystal display guiding device in the second liquid crystal display back, the second liquid crystal display guiding device comprises second light guide plate;
Described first light guide plate and second light guide plate combine, and are embedded with the optical fiber light emitting source between them;
The optical fiber light emitting source is the fiber cores of peeling printing opacity, and at least one end of fiber cores connects the LED light emitting source.
Preferably: described LED light emitting source comprises the coupling mechanism that is connected with fiber cores and the LED lamp on coupling mechanism of ining succession.
Preferably: the two ends of described fiber cores all are connected with the LED light emitting source.
Preferably: an end of described fiber cores connects reflective membrane.
Preferably: described first light guide plate and described second light guide plate are linked to be a light guide plate community, are provided with the through hole that a described fiber cores of confession is inserted in the middle of light guide plate community.
Preferably: be equipped with the groove of ccontaining described fiber cores on the surface of described first light guide plate and described second light guide plate, the second groove amalgamation on first groove on first light guide plate and second light guide plate together just can ccontaining described fiber cores.
Preferably: described LED lamp synthesizes for three-primary colours LED.
Compared to existing technology, the utility model is by a kind of guiding device of symmetry, in conjunction with the characteristics of the parallel light conducting of optical fiber, make full use of the highlighted characteristic of LED, realized integrated double end display screen on same display, and backlight luminescence is even, display effect is stable, and the LED that is positioned at two ends is also convenient to dispel the heat by heating radiator is installed, and this makes that whole display with double faces is simple in structure, volume can be done very for a short time, and is with low cost.
