Description
Technical field
The present invention is relevant for a kind of image element circuit structure, and particularly relevant for a kind of image element circuit structure that is applied to display panels.
Background technology
Because consumption electronic products, and even as personal digital assistant, mobile phone, notebook computer, the large-sized flat-surface television of projector, grow up fast in its consumption market, the demand that also drives display panels (Liqiuid Crystal Display panel, LCD panel) increases.And along with the maturation and the development of technology in market, the consumer has more and more high requirement for the display effect of display panels.
Display panels can be divided into transmission-type (transmissive), reflective (reflective) and three kinds of fundamental types of semi-penetrating trans (tranflective) according to the source reflection mode.The transmissive liquid crystal display panel utilizes backlight module to provide the light transmission to reach transmission-type by display panels to show that its advantage is that display effect is good under ordinary ray and half-light line, but out of doors under the daylight, then is difficult for the identification displaying contents.The reflection type liquid crystal display screen does not need to add light source, but utilize reflect ambient light as light source with display frame, therefore out of doors or well-lightedly indoor good display effect is arranged, and power consumption low than the transmissive liquid crystal display screen.Yet reflecting type liquid crystal display panel is dim indoor, and the occasion of perhaps not having ambient light just can't display frame.Semi-penetrating trans liquid crystal display panel then combines transmission-type and reflective both advantage, therefore becomes one of important research and development direction of industry at present.
Please refer to Fig. 1, it represents the synoptic diagram of the single pixel of traditional transflective liquid crystal display panel.At present traditional transflective liquid crystal display panel 10 comprise a upper substrate 14, an infrabasal plate 11 and be filled in upper substrate 14 and infrabasal plate 11 between liquid crystal layer 15, and have a transmission area a1 and an echo area a2 in the single pixel of transflective liquid crystal display panel 10.Position corresponding to echo area a2 on infrabasal plate 11 also comprises an organic layer 16.Surperficial tool one transparency electrode 12 and a reflecting electrode 17 of infrabasal plate 11, this transparency electrode 12 is corresponding to transmission area a1, reflecting electrode 1 should be in echo area a2, and wherein transparency electrode 12 is electrically connected with reflecting electrode 17, and the surface of upper substrate 14 has community electrode 13.Utilization puts on transparency electrode 12 and reflecting electrode 17 voltage swing corresponding to common electrode 13, to change the orientation of liquid crystal molecule in the liquid crystal layer 15.The source light e1 that backlight module 20 is provided enters transflective liquid crystal display panel 10 by transmission area a1 transmission by infrabasal plate 11 and transparency electrode 12, and then passes through liquid crystal layer 15, common electrode 13 and upper substrate 14 with display frame.Ambient light e2 transmission enters in the transflective liquid crystal display panel 10 by upper substrate 14 and common electrode 13, and via reflecting electrode 17 reflections, transmission is left transflective liquid crystal display panel 10 by upper substrate 14 and common electrode 13 once more.
The optical transmission rate changes along with the difference of Liquid Crystal Molecules Alignment mode in the liquid crystal layer 15, and by the voltage swing that control is applied corresponding to common electrode 13 transparency electrode 12 and reflecting electrode 17, display element can demonstrate the brightness of different gray scales.Organic layer 16 has a thickness, makes between the a2 of echo area crack d2 less than crack d1 between the transmission area a1, allows the interior ambient light e2 of source light e1 and echo area a2 in the transmission area a1 have identical optical path difference, to improve the optical efficiency of liquid crystal.The design of right this kind double gap (dualgap) can make that the complexity of making increases, yield reduces, and production cost also improves relatively.And easily the organic layer thickness inequality because of the double gap structure causes the uniformity coefficient of contrast, color and the transmissivity of transflective liquid crystal display panel 10 integral body to reduce.
