And the LCD panel can implement reflective and transmission display. And the invention also relates to a LCD device using it.
Description
[technical field]
The present invention relates to a kind of display panels and liquid crystal indicator of realizing reflecting and penetrating demonstration.
[background technology]
Advantage such as that liquid crystal indicator has is frivolous, little power consumption, radiation are low is widely used in electronic display units such as notebook computer, mobile phone, electronic dictionary, LCD TV.In recent years along with the continuous development and the popularization of lcd technology, variation has also taken place in its environment for use, time in outdoor application constantly increases, and industry has now been developed a kind of display panels that can use in any environment be semi-reflecting liquid-crystal displaying panel.Semi-reflecting liquid-crystal displaying panel is the main element of power saving type portability type display device, has reflective-mode concurrently and penetrates two kinds of display modes of pattern.When external environment light is sufficient, can utilize surround lighting with reflective-mode work; When external environment light is not enough, can open backlight to penetrate pattern work.
A kind of prior art display panels, as shown in Figure 1.This display panels 10 from up to down comprises polaroid 1 on, one first polarizer 2, one second polarizer 3, one first substrate 4, colored filter 5, one first electrode layer 6, one first alignment film 7, a liquid crystal layer 8, one second alignment film 17, a second electrode lay 16, one second substrate 14, polaroid 11 once successively, and this second electrode lay 16 comprises reflector space 161 and penetration region 162.
This display panels 10 mainly utilizes the reflector space 161 of this second electrode lay 16 and penetration region 162 to realize reflection and penetrate demonstration.When reflection shows, can obtain to penetrate this colored filter 5 after 161 reflections of this reflector space coloured light, be somebody's turn to do coloured light and also need penetrating this colored filter 5 again and realize that the high brightness coloured image shows.Penetrating when showing, obtain to penetrate this colored filter 5 coloured light through this first substrate 4 directly from these display panels 10 outgoing, show with the coloured image of realizing high-contrast.
This display panels 10 need penetrate this colored filter 5 twice when reflection shows, the display color degree was higher when its reflection showed, only penetrate colored filter 5 once and penetrate when showing, therefore, this display panels 10 display color degree when penetrating demonstration is greatly diminished, and causes the difficult allotment of display color of this display panels 10.Again because this display panels 10 need penetrate this colored filter 5 twice when reflection shows, optical loss is bigger, and reflectivity is lower, when external environment light is strong, its visuality reduces greatly, and this problem also is the common defects of present common liquid crystals display panel.
[summary of the invention]
For overcoming the difficult allotment of prior art display panels display color, shortcoming that reflectivity is low, be necessary to provide that a kind of display color is easily allocated, the reflectivity height, and, can realize reflecting and penetrating the display panels of demonstration.
For overcoming the difficult allotment of prior art display panels display color, shortcoming that reflectivity is low, be necessary to provide that a kind of display color is easily allocated, the reflectivity height, and, can realize reflecting and penetrating the liquid crystal indicator of demonstration.
A kind of display panels, comprise first substrate that is oppositely arranged and second substrate, the liquid crystal layer between this first substrate and second substrate, with the electrode layer and the colored filter of the adjacent setting of this first substrate, this electrode layer comprises reflector space and penetration region.When bright and clear, light penetrates this second substrate and this liquid crystal layer earlier successively, arrives this electrode layer in the external world, after the reflector space reflection through this electrode layer, penetrates this liquid crystal layer and this second substrate more successively, display image; When extraneous insufficient light, light penetrates penetration region, this liquid crystal layer and this second substrate of this colored filter, this electrode layer, display image successively.
A kind of liquid crystal indicator, comprise first substrate and second substrate that are oppositely arranged, liquid crystal layer between this first substrate and second substrate, one with the electrode layer and the colored filter of the adjacent setting of this first substrate, one is arranged at the module backlight of this first substrate below, this electrode layer comprises reflector space and penetration region, it is characterized in that: in the external world when bright and clear, extraneous light penetrates earlier this second substrate and this liquid crystal layer successively, arrive this electrode layer, after the reflector space reflection through this electrode layer, penetrate this liquid crystal layer and this second substrate more successively, display image; When extraneous insufficient light, the light that this module backlight sends penetrates penetration region, this liquid crystal layer and this second substrate of this colored filter, this electrode layer, display image successively.
Compared with prior art, above-mentioned display panels is when extraneous surround lighting is sufficient, and it is painted that light does not pass through this colored filter, conducts with non-staining light, shows black white image from this display panels outgoing at last, with reflective-mode work.Light need not pass through colored filter when this display panels was worked with reflective-mode, had improved reflectivity greatly, reduced optical loss, had improved display brightness.Simultaneously, because it shows black white image,, improved the visuality under high light even its image is still high-visible when extraneous ambient light is strong.
This display panels is when extraneous surround lighting is not enough, can add a module backlight is its additional light, light is painted and forming coloured light through this colored filter, is being somebody's turn to do coloured light at last from this display panels outgoing color display, to penetrate pattern work.When working with reflective-mode, this display panels shows black white image, high and the problem that the display color degree reduces greatly when working with the pattern that penetrates of its display color degree when work with reflective-mode to penetrate pattern when work color display, can solve the prior art display panels.Display color when this display panels is worked with the reflection and the pattern that penetrates is very easily allocated.
