By above-mentioned accompanying drawing, the embodiment that the present invention is clear and definite has been shown, will there is hereinafter more detailed description.These accompanying drawings and text description are not the scope in order to limit the present invention's design by any mode, but logicalCross with reference to specific embodiment for those skilled in the art illustrate concept of the present invention.
Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to thisBright being described in further detail, obviously, described embodiment is only a part of embodiment of the present invention,Instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not doingGo out all other embodiment that obtain under creative work prerequisite, all belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of display base plate 00, as Figure 1-1, comprising:
Underlay substrate 01;
On underlay substrate 01, be formed with multiple electrophoretic cells 02;
Be formed with on the underlay substrate 01 of electrophoretic cell 02 and be formed with black matrix 03;
Be formed with on the underlay substrate 01 of black matrix 03 and be formed with color filter layer 04;
Wherein, the orthographic projection of electrophoretic cell 02 on underlay substrate 01 is positioned at black matrix 03 at underlay substrate 01Orthographic projection in, can ensure that like this shape of electrophoretic cell and black matrix match, and avoid electrophoretic cell shadowRing the display performance of display base plate, optional, in order to ensure that multiple electrophoretic cells do not affect the aobvious of display floaterExpressivity energy, the region that need to make multiple electrophoretic cells block in black matrix, for example, multiple electrophoretic cellsOn underlay substrate, form the latticed region identical with black matrix shape; Or multiple electrophoretic cells are at liningOn substrate, form along data wire direction or along multiple bar-shaped zones of grid line scanning direction array arrangement.
As shown in Figure 1-2, electrophoretic cell 02 comprises: transparent enclosed construction 021, is wrapped in transparent sealing knotElectrophoresis liquid 022 in structure 021, and be arranged in the opposite polarity white electrophoretic particles 023 of electrophoresis liquid 022With black electrophoretic particles 024. White electrophoretic particles 023 in electrophoretic cell 02 and black electrophoretic particles 024Position can under applied voltage effect, change. Wherein, transparent enclosed construction is can deformation transparent capsule,Can be made by materials such as silica gel, avoid electrophoretic cell 02 fragmentation in the time being subject to ambient pressure, ensure electrophoresis listUnit is easy damaged not, and this transparent enclosed construction 021 is normally colourless, can be spherical, elliposoidal, cubeBody or rectangular structure, the embodiment of the present invention does not limit this, and electrophoresis liquid 022 refers to is carrying out electrophoresisTime the cushioning liquid that uses, can be water white liquid. Electrophoresis (electrophoresis) refers to bandElectricity particle, under electric field action, moves towards the electrode electrically contrary with it. In the embodiment of the present invention, electrophoresisThe principle that operation principle of unit adopts above-mentioned electrophoresis to produce.
In sum, the display base plate that the embodiment of the present invention provides, due between black matrix and underlay substrateForm multiple electrophoretic cells, and white electrophoretic particles in this electrophoretic cell and the position of black electrophoretic particlesCan under applied voltage effect, change,, in the time adopting this display base plate to carry out image demonstration, can pass throughThat applied voltage is controlled is black, the change in location of white electrophoresis particle, when white electrophoretic particles is during near underlay substrate,Can reflect ambient light, thus certain display brightness produced, share backlight (English: BackLightUnit; Be called for short: BLU) the required brightness providing, has therefore reduced the power consumption of backlight, thereby has reduced aobviousThe overall power of showing device.
Optionally, as Figure 1-3, on underlay substrate 01, can be formed with metal electrode 05, metal electrode05 for applied voltage is provided, so that effectively providing of applied voltage to be provided; Be formed with the lining of metal electrode 05On substrate 01, be formed with electrophoretic cell 02. White electrophoretic particles 023 in electrophoretic cell 02 and black electricityUnder the applied voltage effect that the position of swimming particle 024 can provide at metal electrode 05, change. For example white electricitySwimming particle electronegative, black electrophoretic particles band on schedule, by applying positive electricity to metal electrode, white electrophoresis grainSon gathers underlay substrate one side, and surround lighting that can reflective substrate outside increases the brightness of display base plate;By applying negative electricity to metal electrode, black electrophoretic particles gathers underlay substrate one side, with the work of black matrixWith identical, can promote black state display effect. It should be noted that, white electrophoretic particles also can positively charged,Black electrophoretic particles is electronegative, and the embodiment of the present invention does not limit this, as long as two kinds of electrophoresis particles of guaranteePolarity is contrary.
Optionally, this metal electrode 05 can be transparent metal electrode. As Figure 1-3, this transparent metalElectrode can be the metal electrode layer of intact, and as Figure 1-4, this transparent metal electrode also can formDefault metal electrode figure, this default metal electrode figure can be relevant to the shape of black matrix, for example electrophoresisThe orthographic projection of unit on underlay substrate is positioned at the orthographic projection of transparent metal electrode at underlay substrate, transparent goldBelong to the orthographic projection of electrode on underlay substrate and be positioned at the orthographic projection of black matrix at underlay substrate. Example, shouldTransparent metal electrode can be tin indium oxide (English: IndiumTinOxides; Be called for short: ITO).
Optionally, this metal electrode 05 can be non-transparent metals electrode, in order to ensure metal electrode and electrophoresisUnit does not affect the display performance of display floater, need to make metal electrode and electrophoretic cell hide in black matrixIn the region of gear, example, as Figure 1-4, the orthographic projection of electrophoretic cell on underlay substrate is positioned at metalElectrode is in the orthographic projection of underlay substrate, and the orthographic projection of metal electrode on underlay substrate is positioned at black matrix at liningIn the orthographic projection of substrate.
Optionally, in order to ensure that metal electrode 05 does not affect the display performance of display floater, need to make metalThe region that electrode 05 blocks in black matrix, on the one hand, metal electrode 05 can be formed directly into substrate-basedOn plate, but in order to reduce the thickness of display base plate, metal electrode can be arranged on to the groove of underlay substrateIn, as Figure 1-5, for example, on underlay substrate 01, be formed with multiple grooves 011, multiple grooves 011On underlay substrate, form the latticed region identical with black matrix 03 shape; Or multiple grooves 011 existOn underlay substrate 01, form along data wire direction or along multiple bar-shaped zones of grid line scanning direction array arrangement;Metal electrode 05 is formed in groove 011.
