Abstract
A display with dual-surface display function is composed of the mutually opposite two display panels and a back light plate between them.
Description
(1) technical field
The relevant a kind of display of the present invention, and particularly relevant a kind of display with double-sided display function.
(2) background technology
In recent years, Thin Film Transistor-LCD (TFT-LCD) is widely used gradually because of having advantages such as thin, the in light weight and low electromagnetic of volume.General Thin Film Transistor-LCD mainly comprises a display panel and a backlight assembly, has the function that single face shows.The backlight assembly that utilization has a plurality of light sources provides display panel to show required uniform light, and with the difference of its light source configuration mode of backlight assembly and the difference of principle of luminosity thereof, generally is divided into two kinds of side formula backlight assembly and direct type backlight assemblies.
Please be simultaneously with reference to Figure 1A and Figure 1B, Figure 1A is the decomposing schematic representation of conventional liquid crystal, and Figure 1B is the diagrammatic cross-section according to the LCD of Figure 1A.Traditional LCD 100 includes a display panel 110 and a direct type backlight assembly (direct back light module) 120.Backlight assembly 120 comprises blooming 123, reflector plate 124, a plurality of light source 122 and lamp socket 121.Lamp socket 121 be in order to putting a plurality of light sources 122, and light source 122 for example is several cold-cathode tubes, in order to provide display panel 110 even and sufficient light, to show preferable image display quality.On lamp socket 121, dispose a reflector plate 124,, leak outside to prevent light in order to reflection ray.Blooming 123 is to be disposed between backlight assembly 120 and the display panel 110, in order to will spread and be directed to display panel 110 equably from the light that light source 122 is dispersed.Blooming 123 is the structure of a multilayer, includes diffusion sheet (diffusing sheet) and prismatic lens (prism sheet).In addition, a display panel 110 and a control circuit board 125 electrically connect, and the orientation of the liquid crystal molecule in each pixel of the control circuit may command display panel 110 on the control circuit board 125 when treating that light passes through display panel 110, will show corresponding picture.
Yet along with making rapid progress of science and technology, single LCD with single face Presentation Function of only making has been not enough to adapt to the fast changing market demand, so there's no one who doesn't or isn't endeavour to innovate and the function and the usefulness of promoting LCD for the practitioner of LCD.Making a LCD with double-sided display function is one of numerous reform and development directions, because of LCD with double-sided display function has not only been Duoed the Presentation Function on another plane than general single face LCD, light and handy fuselage design is compared with two independent themselves one-sided displays, having more excellent portability, is the advantageous feature in numerous innovation reforms.
(3) summary of the invention
In view of this, purpose of the present invention just provides a kind of display with double-sided display function, comprises that two relative to each other display panels and are disposed at the direct type backlight assembly between two display panels.Can disperse equably toward the both sides of backlight assembly by the light that backlight assembly penetrates, the required light of two display panels is provided respectively and reaches the effect of double-sided display.
According to purpose of the present invention, a kind of display with double-sided display function is proposed, comprise one first display panel, one second display panel and be disposed at a direct type backlight assembly between two display panels.Backlight assembly comprises a plurality of light sources and a lamp socket, and lamp socket is in order to the storing light source, and light source is in order to provide two display panels to show required light.Dispose the side of a control circuit board in first display panel and second control circuit plate respectively, two bloomings then are disposed at respectively between backlight assembly and two display panels.Light source is a plurality of cold-cathode tubes, and linear pattern is arranged in the lamp socket, and can dispose a reflector plate between adjacent two light sources in addition, to increase the service efficiency of light source.The material of reflector plate is one to have the material of high reflectance, and this material with high reflectance is formed this reflector plate in the mode of sputter.When light when light source is dispersed toward the both sides of backlight assembly, penetrate the blooming of both sides, after diffuse to two display panels equably, and make display reach the effect of double-sided display.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
