Embodiment
At first, see also Fig. 1, be used for illustrating the structure of double-sided display LCD of the present invention.As shown in Figure 1, this LCD structure has:
One first substrate 100 is thin film transistor (TFT) array substrate of glass (TFTs array glasssubstrate);
One transparent insulating layer 110 can be formed on the inboard of above-mentioned first substrate 100, and its material can be an organic material;
One reflecting electrode pattern (reflective electrode pattern), 120 and one transparent electrode pattern (transparent electrode pattern) 125, be formed on the above-mentioned transparent insulating layer 110, wherein above-mentioned reflecting electrode pattern 120 can be according to traditional deposition and lithography program with the generation type of transparent electrode pattern 125, because of generation type is not this pattern characteristics emphasis, no longer given unnecessary details at this.Then, just construct, reflecting electrode pattern 120 is to be positioned among above-mentioned first screen area 101, and transparent electrode pattern 125 then is to be positioned among second screen area 102.In addition, the material of reflecting electrode pattern 120 can be aluminium or silver, and the material of transparent electrode pattern 125 can be to plug with molten metal tin-oxide (ITO) or plug with molten metal zinc oxide (IZO).
One second substrate 190, this second substrate 190 be subtend in above-mentioned first substrate 100, and its material can be glass, or other material that is fit to;
One optical filter 180 is formed on second substrate 190, and wherein optical filter 180 optionally uses colored filter or black and white optical filter, in this preferred embodiment, is to use colored filter;
One common electrode (common electrode) 170 is formed on the optical filter 180, and wherein the material of common electrode 170 can be to plug with molten metal tin-oxide (ITO) or plug with molten metal zinc oxide (IZO);
One liquid crystal layer 160 is formed between above-mentioned first substrate 100 and second substrate 190, and its generation type is directly liquid crystal material to be injected between first substrate 100 and this second substrate 190, and forms the liquid crystal layer of being wanted 160;
One reflecting plate 150, optionally be formed at the outside or the inboard of position in second substrate 190 of second screen area 102, in the present embodiment, be that reflecting plate 150 is formed at the outside of position in second substrate 190 of second screen area 102, wherein the material of reflecting plate 150 can be aluminium or silver, or the direct casing inboard that scribbles the reflection horizon of LCD is used as is reflecting plate 150.
One light-emitting device 200 can be arranged between above-mentioned second substrate 190 and the reflecting plate 150.Wherein, if light-emitting device 200 is when being out state (ON state), then to be taken as be the front light-source (frontlight) of first screen area 101 and the backlight (backlight) of second screen area 102 to this light-emitting device 200.If when light-emitting device 200 is when being off status (OFF state), then first screen area 101 and second screen area 102 are that to be used as be reflection source to the employing surround lighting.In a preferred embodiment, this light-emitting device 200 includes the illuminating module of a cold-cathode tube (cold cathode fluorescenttube) and a light guide plate (light guide panel).
Liquid crystal display device structure according to the disclosed double-sided display type of the present invention, see also Fig. 1, the liquid crystal display device structure of its meta in first screen area 101 is to be that a reflective liquid-crystal display structure (symbol 201 is expression reflected light), the liquid crystal display device structure of its meta in second screen area 102 then are a penetrating LCD structure (symbol 202 is that expression penetrates light) or a reflective liquid-crystal display structure (symbol 203 is expression reflected light).Wanting ben in addition is that first screen area 101 and second screen area 102 can be adjacent one another are or non-conterminous according to considering of this LCD mechanism design.
Via the disclosed LCD structure of the present invention, can use same set of LCD to show the data on positive and negative two sides, therefore only need a cover electronic installation to drive the LCD of above-mentioned double-sided display, the result not only makes cost reduce, also make the thickness that reduces product, and meet frivolous weak point, little product trend.
