Description
Technical field
The invention belongs to flat panel display technology, more particularly to one kind to have high aperture and high-resolution pixel arrangement knot
Structure and apply its organic electroluminescence display panel.
Background technology
Organic electroluminescence display panel (English full name is Organic Light-Emitting Display, abbreviation OLED) has
Have actively that luminous, frivolous, visual angle is big, fast response time, energy-conservation, temperature tolerance range are big, Flexible Displays can be achieved and transparent show
The advantages that showing, it is considered to be most potential novel flat-plate Display Technique of future generation.
In existing organic electroluminescence display panel true color method, red, green, blueness (three primary colours Red, Green,
Blue, abbreviation RGB) pixel juxtaposition method and colored filter (English full name is color filter, referred to as CF) method be current
The most ripe two methods of development.Rgb pixel juxtaposition method needs high-precision metal mask to realize high-resolution, and cost is very
Height, and the uniform preparation of large area is difficult to, therefore the colored filter method of the full-color display of similar liquid crystal panel field obtains
The attention of industry is arrived, i.e., white organic LED plays backlight and liquid crystal molecule in liquid crystal panel as backlight
Effect, it is subject to optical filter again above with real red, green, blue subpixels, so can be good at solving resolution ratio and big
The problem of prepared by area.
However, because light is by having larger energy loss after colored filter, display panel power consumption is caused to increase,
In order to effectively reduce the power consumption of display panel, it will usually using RGBW (i.e. four primary Red, Green, Blue, white, abbreviation
RGBW) four color pixel arrangement.But due to adding a white light sub-pixel in each pixel cell, it result in again point
The reduction of resolution, have impact on using effect.
Chinese patent literature CN102636894A discloses a kind of display device, as shown in figure 1, each pixel is by R, G, B
Formed with three sub-pixels in W sub-pixel, and the pixel comprising white pixel is public adjacent thereto in multiple pixels
The monochrome sub-pixels included in pixel.Although the pixel arrangement structure can improve resolution ratio to a certain extent, phase
Adjacent pixel cell largely borrows sub-pixel, and picture edge display effect can be caused poor, and drives the problem of complicated, has a strong impact on picture
Face quality and product service life.
The content of the invention
It is that image quality is poor, driving is complicated in existing RGBW pixel arrangement structures therefore, to be solved by this invention to ask
Topic, a kind of image quality is clear, the simple high resolution R GBW pixel arrangement structures of driving so as to providing, and applies its organic light emission
Display panel.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of pixel arrangement structure of the present invention, including m rows, the pixel cell of n row first, often go adjacent described first

Unit includes the white sub-pixels, and two neighboring second pixel cell is not only white sub-pixels entirely；Two neighboring
One pixel cell shares the second pixel cell between the two；M is non-zero natural number, and n is the natural number not less than 2.
A kind of pixel arrangement structure of the present invention, including m rows, the pixel cell of n row first, often in odd-numbered line, part
The second pixel cell is provided between adjacent first pixel cell；First pixel cell includes coplanar juxtaposed red
Sub-pixels, green sub-pixels and blue subpixels, second pixel cell are white sub-pixels；Second pixel cell
Shared by two first pixel cells adjacent thereto；M is non-zero natural number, and n is the even number not less than 2.
The white sub-pixels, the blue subpixels are in bar shaped, and its length direction is vertical with line direction.
The red sub-pixel and the green sub-pixels are in bar shaped, and its length direction is vertical with line direction, along row
Direction is set up in parallel.
The red sub-pixel is set up in parallel with the green sub-pixels along column direction, both length in a column direction it
With the length less than the white sub-pixels or the blue subpixels in a column direction.
Along column direction, adjacent rows pixel arrangement structure is in mutually mirror.
The white sub-pixels aperture area is more than or equal to the aperture area of the blue subpixels；The sub- picture of blueness
The aperture area of element is more than or equal to the area of the red sub-pixel；The aperture area of the blue subpixels is more than or equal to
The area of the green sub-pixels.
A kind of organic electroluminescence display panel of the present invention, including white organic LED array, and set
Colored filter on the white organic LED array exiting surface, the colored filter have described pixel
Arrangement.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art：
Pixel arrangement structure provided by the invention, each first pixel cell include coplanar juxtaposed red sub-pixel
And green sub-pixels, two neighboring first pixel cell of going together, which shares one, includes white sub-pixels and/or blue subpixels
Second pixel cell.At least one second pixel cell includes the white sub-pixels, two neighboring second pixel
Unit is not only white sub-pixels entirely, and adjacent two first pixel cells share second pixel cell；Adjacent
One pixel cell shares that monochrome sub-pixels are few even without shared sub-pixel, and image quality is clear, drive system is simple, avoid due to
Caused by the sub-pixel of a large amount of shared different colours the problem of driving algorithm complexity, and then avoid resulting driving chip
The rising of cost, service life length；Meanwhile only adjacent first pixel cell in part shares white sub-pixels and blue subpixels,
Pixel openings area is big, high resolution.Moreover, being provided with white sub-pixels, display brightness, softening display effect can be effectively improved
Fruit, so as to reduce power consumption, improve using effect.
Another pixel arrangement structure provided by the invention, first pixel cell include coplanar juxtaposed red son
Pixel, green sub-pixels and blue subpixels, second pixel cell are white sub-pixels；Adjacent the first pixel list
Member shares second pixel cell；Each first pixel cell includes RGB three primary colours, only shares adjacent white light picture
Element, avoid due to the problem of driving algorithm complexity caused by a large amount of sub-pixels for sharing different colours, and then avoid thus
The rising of caused driving chip cost, and still have and improve display brightness, the effect that softening is shown.
