Description
Technical field
The present invention relates to a kind of flat-panel screens technology, the reflective liquid-crystal display device of particularly a kind of integration front optical module (front light module).
Background technology
Because the characteristic of thin thickness, in light weight and low power consumption, LCD is widely used in the electronic installation, for example luggable computer, PDA(Personal Digital Assistant), and mobile phone etc.Usually LCD is divided into penetration and reflective two types.The former utilizes backlight module (back light module) as light source, and the latter then utilizes surround lighting as light source.Penetrating LCD can present high contrast ratio and good color saturation.Yet, because the electricity needs of backlight module makes the LCD of penetration be difficult to effectively reduce the loss of electric power.
The LCD that is different from penetration, reflective liquid-crystal display can utilize surround lighting to have the advantage of power saving as light source under bright surround lighting.In order to operate reflective liquid-crystal display under dim surround lighting, reflective liquid-crystal display also needs extra assembling front optical module usually, thereby as penetrating LCD, can't effectively reduce the display integral thickness and reduce manufacturing cost.
Yet, along with the upwards development of electronic product, the thickness of above-mentioned LCD, weight, and power consumption do not met current requirements.Therefore, be necessary to seek a kind of new liquid crystal indicator structure, it can improve thickness, weight and the power consumption of display itself.
Summary of the invention
One embodiment of the invention provides a kind of image display system, comprising: reflective LCD device, it comprises: first substrate, second substrate, liquid crystal layer, a plurality of first electrode, second electrode, and organic luminous layer.First substrate has pixel unit array.Second substrate is arranged at first substrate top and liquid crystal layer is arranged between first substrate and second substrate.First electrode is arranged between second substrate and the liquid crystal layer and corresponding to each pixel cell of pixel unit array, wherein pixel cell comprises reflecting electrode.Second electrode is arranged between first electrode and the liquid crystal layer, with the public electrode as the control liquid crystal layer.Organic luminous layer is arranged between first electrode and second electrode, wherein first electrode, second electrode, and organic luminous layer constitute light-emitting device, to provide light source to reflecting electrode.

Embodiment
The below making and the use of the explanation embodiment of the invention.Yet, can understand embodiment provided by the present invention easily and only be used for explanation with ad hoc approach making and use the present invention, be not in order to limit to scope of the present invention.
The image display system of the embodiment of the invention below is described.Fig. 1 shows the image display system diagrammatic cross-section with reflective LCD device 200 according to the embodiment of the invention.In the present embodiment, reflective LCD device 200 comprises first substrate 100, second substrate 116, liquid crystal layer 104, reaches the light-emitting device as front located light source (front light source).
Please refer to Fig. 2, it shows pixel cell 102a diagrammatic cross-section among Fig. 1.In one embodiment, pixel cell 102a can comprise: and two thin film transistor (TFT)s (thin film transistor, TFT) 20 and 30, storage capacitors 40 and pixel electrode 80.Thin film transistor (TFT) 20 and 30 and storage capacitors 40 be attached on first substrate 100 by cushion 10 usually.First middle layer 50, second middle layer 60 and protective seam 70 are stacked in thin film transistor (TFT) 20 and 30 and storage capacitors 40 tops in regular turn.Pixel electrode 80 is arranged at protective seam 70 tops in order to the reflecting electrode as reflective LCD device 200, and it comprises nontransparent reflecting material, for example metal.In other embodiments, pixel electrode 80 can comprise nontransparent reflecting material and transparent conductive material, for example indium tin oxide (indium tin oxide, ITO).Moreover, pixel electrode 80 by be formed in first middle layer 50 and second middle layer 60 conductive plungers 55 and with thin film transistor (TFT) 20 and 30 and storage capacitors 40 electrically connect.
Have the first electrode wiring 110a and the second electrode wiring 106a on second substrate 116 corresponding to non-display area II, in order to first substrate 100 on different metal line 118 electrically connect.In one embodiment, the first electrode wiring 110a and the second electrode wiring 106a can pass through metal lotion (metal paste) 120 and metal line 118 electric connections.In another embodiment, the first electrode wiring 110a and the second electrode wiring 106a can utilize anisotropic conductive film (anisotropic conductive film ACF) electrically connects with metal line 118.
Organic luminous layer 108 is arranged between first electrode 110 and second electrode 106.In other embodiments, can replace single organic luminous layer 108 corresponding to a plurality of organic light emission patterned layer (not illustrating) of each first electrode 110.
