Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
First the present invention provides a kind of display panel, and structure as shown in Figure 1, comprising:
Array base palte 102, is positioned at the colour filter 101 of array base palte light emission side; Described colour filter 101 comprises multiple micro mirror unit 1011, pixel cell arranged with each pixel cell 1021 one_to_one corresponding on array base palte 102 and comprises three sub-pixel unit 1021; Described micro mirror unit 1011 for filtering the white light through array base palte 102, be separated, obtain respectively with described three sub-pixs 1021 three primary colours light one to one.
The present invention adopts colour filter to substitute in display panel for generation of monochromatic color membrane substrates, the white light of incidence carries out filtering, being separated the multiple monochromatic light of formation by colour filter, this process is an optical imaging procedures, the colourity of colour filter can not be caused to weaken because of the increase of service time, the phenomenon that also can not be deteriorated because of the increase brightness of displaying time.And micro mirror unit is small optical frames assembly simultaneously, manufacturing process is simple, and without the need to exposing separately the sub-pix of different colours, develop, manufacture process have also been obtained simplification, and production efficiency is improved, and display effect can not be adversely affected.
In prior art, when making color membrane substrates, first make black matrix, then successively form red sub-pixel, green sub-pixels, blue subpixels successively by negative photoresist deposition, exposure imaging, finally sputter, thus form color membrane substrates.And micro mirror unit provided by the present invention, multiple monochromatic light can be produced, comprise ruddiness, green glow, blue light, its effect is identical with a pixel cell of color membrane substrates, but without the need to manufacturing respectively each monochromatic part of generation, only need the optical filtering of micro mirror unit and/or reflective mirror to carry out assembling.Thus, the manufacturing time significantly reduces, and manufacture difficulty is also reduced.
In the specific embodiment of the invention, described micro mirror unit comprises multiple optical frames, can be specifically lens, reflective mirror, reflecting coating, light-absorbing layer etc.Described colour filter be not limited only to literal meaning indication for filtering monochromatic light mirror, also can comprise reflective mirror etc.
Described multiple micro mirror unit is arranged in array at described colour filter.
In the specific embodiment of the invention, described three primary colours light is the monochromatic light of RGB three kinds of colors.
The color membrane substrates of prior art is formed with black matrix, as the cut-off rule of the sub-pix of RGB three kinds of colors, avoids colour contamination between different sub-pix.And be parallel to each other at the monochromatic light light that the exiting surface of micro mirror unit of the present invention sends, and the monochromatic light of different colours can be made by specific reflective mirror or optical filtering injection micro mirror unit, thus can not mix with other monochromatic light at the light that different reflective mirrors or optical filtering place finally shine beyond micro mirror unit.Thus by rationally arranging reflective mirror or optical filtering or other optical device in micro mirror unit, can allow display panel that black matrix is no longer set, thus further simplify the manufacturing process of display panel, and then improve yields and the turnout of display panel making.Display panel provided by the invention can be applied and LCD (LiquidCrystalDisplay, liquid crystal display), LED (LightEmittingDiode, light emitting diode), AMOLED (Active-matrixorganiclightemittingdiode, active matrix organic light-emitting diode or active-matrix organic light emitting diode), TN (twistednematic distortion arranges in detail) display, ADS (AdvancedSuperDimensionSwitch, senior super Wei Chang conversion) display, SLOC (singlelayeroncell, glass shows single layer pattern) application in the display such as display field.
In most of the cases, no matter be color membrane substrates or colour filter provided by the present invention, be generally used for and utilize incident white light to produce red, green, blue three kinds of basic monochromatic light.
