Embodiment
The present invention is divided into two zones at least with the viewing area of display panels, and is used for wherein showing that the zone of information commonly used has higher reflectivity.When the user need read the information commonly used in this zone, do not need to open backlight, as long as utilize external surround lighting, can learn these information, and then reach the purpose of saving product power.
Below, be the detailed description that application product is made embodiments of the invention with a mobile phone.Yet the applicable product of the present invention is numerous, does not use with mobile phone and exceeds.In addition, diagram is omitted unnecessary element, with the clear embodiments of the invention that show.
Please refer to Fig. 1, it illustrates the synoptic diagram according to the display panels of one embodiment of the present invention.The display panels 1 of mobile phone comprises a pixel region 12 and one drive circuit zone 14, and pixel region 12 is electrically connected with drive circuit area 14.Wherein, pixel region 12 also comprises one first viewing area 121 and one second viewing area 122, and first reflectivity of first viewing area 121 is greater than second reflectivity of second viewing area 122.The information commonly used of mobile phone then is shown in first viewing area 121, do not needing to open under the situation backlight, as long as the user utilizes external surround lighting, can read these information commonly used of first viewing area 121 that is positioned at high reflectance, and then reach the purpose of saving product power.When practical application, first area of first viewing area 121 is less than the second area of second viewing area 122.
Display panels can be divided into three types of penetration (transmissive), reflective (reflective) and Transflectives (transflective) etc. according to the reflection mode.Penetrate through type liquid crystal display board reaches penetration with back light and shows 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.Reflecting type liquid crystal display panel does not need to add light source, and is to use the light of surrounding environment, therefore out of doors or the well-lighted indoor good display effect that has, and power consumption low than penetrate through type liquid crystal display board.Half-penetration half-reflection liquid crystal display panel then combines penetration and reflective both advantage, is applied to products such as mobile phone or personal digital assistant at present more.In addition, micro-reflection type (micro-reflective) display panels is wherein of half-penetration half-reflection liquid crystal display panel, the advantage that not only has Transflective, can solve in the sun and can't identification to show the problem of information because surface reflection is crossed strong, and do not need extra adding technology, can in general penetration display panel, make little reflecting element, can save manufacturing cost.Therefore, one of them selects a micro-reflection type dot structure first viewing area 121 of the present invention and second viewing area 122, and another then is penetration dot structure, reflective pixel structure or general Transflective dot structure.
For example: when the first higher viewing area 121 of reflectivity had the micro-reflection type dot structure, second viewing area 122 can make the penetration dot structure.If when the micro-reflection type dot structure was formed at lower second viewing area 122 of reflectivity, 121 of first viewing areas can have half penetrated dot structure or reflective pixel structure.
Because penetration (transmissive), reflective (reflective) and Transflective (transflective) display panels are the existing technology of correlative technology field person, below only the micro-reflection type dot structure is elaborated.And the voltage of its echo area of micro-reflection type dot structure that is proposed and the relation curve of reflectivity (V-R) are matched with the voltage of penetrating region and the relation curve of penetrance (V-T).
