Embodiment
In order to more clearly understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not by the restriction of following public specific embodiment.
As shown in Figure 3 and Figure 4, display panel according to an embodiment of the invention, comprise the pixel cell of multiple array arrangement, each pixel cell with a line comprises the regional transmission 1 and reflector space 2 that arrange along column direction, and the transitional region 3 between regional transmission 1 and reflector space 2, the reflector space 2 of two pixel cells adjacent in the pixel cell of adjacent lines is adjacent or regional transmission 1 is adjacent.
According to the present embodiment, the quantity of transitional region in viewing area can be reduced.Such as in the display panel of the prior art shown in Fig. 2, in all pixel cells, reflector space is sequentially all identical with arranging of regional transmission, in adjacent pixel unit reflector space and regional transmission non-conterminous, the viewing area of 4 pixel cells is taken advantage of for 4, just need between adjacent reflector space and regional transmission to arrange a transitional region, so need to arrange 28 transitional regions.
And according to the present embodiment, because the reflector space of two pixel cells adjacent in the pixel cell of adjacent lines is adjacent, or projected area is adjacent, therefore can make between the pixel cell of adjacent lines without the need to arranging transitional region.So as shown in Figure 3, the reflector space of two pixel cells adjacent in the pixel cell of adjacent lines is adjacent, taking advantage of in the viewing area of 4 pixel cells 4 only need reflector space in pixel cell and arrange transitional region between regional transmission, also i.e. only needs 16 transitional regions.
Visible, when not affecting transition effect between adjacent transmissive region and reflector space, the quantity of transitional region in viewing area can be reduced significantly according to the present embodiment, thus improve aperture opening ratio.
Preferably, display panel comprises the capable pixel cell of n, padded layer 4 is provided with in the reflector space of each pixel cell, wherein, 2i is capable with the capable pixel cell of 2i+1 or 2i-1 is capable is connected (as shown in Figure 4) with the padded layer 4 of two pixel cells adjacent in 2i capable pixel element unit, 0<i<n/2, i and n are integer.
According to the present embodiment, because the padded layer of two pixel cells adjacent in adjacent lines is connected, therefore there is not gap, the liquid crystal that is filled on two padded layers can be made more smooth.
Preferably, the padded layer be connected is structure as a whole.By one-time process, padded layer can be set in two row pixel cells, be of value to simplification Making programme.
Preferably, display panel comprises:
Upper substrate and infrabasal plate,
Wherein, padded layer to be arranged on infrabasal plate or under upper substrate (in this case, reflection horizon is arranged on infrabasal plate, light in echo area can be more through the padded layer of layer of transparent than the light in transmission area, but because padded layer can not produce modulating action to light, so display effect can not be affected).Padded layer wherein can be made up of transparent material.
Set-up mode need be carried can select according to actual needs.
As shown in Figure 5, preferably, pixel cell also comprises:
Thin film transistor (TFT) 5;
When padded layer 4 is arranged on infrabasal plate, in reflector space 1, reflection horizon 11 is positioned at above thin film transistor (TFT) 5.
According to the present embodiment, thin film transistor (TFT) can be blocked by reflection horizon, thus block without the need to arranging black matrix (BM) in upper substrate, viewing area can be made to have more light to penetrate, thus improve aperture opening ratio.
Preferably, pixel cell also comprises:
Pixel electrode 6, on the padded layer 4 being arranged on regional transmission 2, transitional region 3 and reflector space 1.
Pixel electrode in the present embodiment can also be arranged on padded layer 4, thus can drive the liquid crystal on reflector space 1, and then improves the area of effective light-emitting zone, thus improves aperture opening ratio.Such as shown in Fig. 6, can realize by arranging layer of transparent conductive layer 7 on pixel electrode 5 and reflection horizon 11.
As shown in Figure 7, preferably, the pixel electrode 5 one-tenth be arranged on transitional region 3 is stepped.
Pixel electrode in the present embodiment on transitional region 3 becomes stepped, such as can by the transparency conducting layer 7 on transitional region 3 is set to stepped realization.According to the present embodiment, the pixel electrode in transitional region 3 has a part of horizontal area, therefore also can play the effect of driven liquid crystal deflection, thus reduces the impact of transitional region 3 on Liquid Crystal Molecules Alignment and driving, improves the printing opacity brightness in this region.
Preferably, order is set with the regional transmission in a line pixel cell and reflector space identical.Be convenient to arrange, thus Simplified flowsheet.
Preferably, order is set with the regional transmission in a line pixel cell and reflector space different.
According to the present embodiment, the regional transmission in same a line pixel cell can be avoided to be positioned at same a line and reflector space is positioned at same a line, thus avoid reflector space brightness and regional transmission luminance difference larger time, the regional transmission with a line and the reflector space with a line form light and shade striped.
Preferably, often row pixel cell comprises multiple pixel cell group, and in same pixel cell group, the regional transmission of pixel cell arranges sequentially identical with reflector space, and in adjacent pixel unit group, the regional transmission of pixel cell arranges sequentially different with reflector space,
Wherein, each pixel cell group comprises at least one pixel cell.
By the present embodiment, that can put upside down primary event region and regional transmission every one or more pixel cells arranges order.As shown in Figure 8, each pixel cell group comprises a pixel cell, and as shown in Figure 9, each pixel cell group comprises two pixel cells, and the pixel cell quantity that concrete each pixel cell group comprises can be arranged as required.
As shown in Figure 10, preferably, regional transmission is different with the area of reflector space.
Because transitional region still can form dark space, if regional transmission is identical with reflector space area, be so positioned on straight line with the transitional region in a line pixel cell, be easily observed comparatively significantly dark line.According to the present embodiment, transitional region in same a line pixel cell can be made not to be positioned on straight line, thus reduce the obvious degree that user watches the dark line of transitional region, and then improve viewing effect.
The invention allows for a kind of display device, comprise above-mentioned display panel.
It should be noted that, the display device in the present embodiment can be: any product or parts with Presentation Function such as Electronic Paper, mobile phone, panel computer, televisor, notebook computer, digital album (digital photo frame), navigating instrument.
More than be described with reference to the accompanying drawings technical scheme of the present invention, considered in prior art, the transitional region between regional transmission and reflector space can reduce aperture opening ratio.By technical scheme of the present invention, when not affecting transition effect between adjacent transmissive region and reflector space, the quantity of transitional region in viewing area can be reduced, thus improve aperture opening ratio.
