Abstract

The present invention relates to a kind of LED array display part for having and sharing individual redundant sub-pixel point, the LED array display part includes the red, green, blue sub-pixel point of dense arrangement, wherein, a red sub-pixel point, a green sub-pixels point and a blue subpixels point form a light emitting pixel unit；Several light emitting pixel units surround an individual redundant sub-pixel point, form a pixel-array unit；And then the densely arranged composition LED array display part of several pixel-array units.The advantage of the invention is that：The present invention both can extend the life-span of array of display by compensation of the individual redundant sub-pixel point to the abnormal sub-pixel point of surrounding, again can be preferably minimized influence of the individual redundant sub-pixel point to array of display resolution ratio；Further, since the area compared with short life sub-pixel point and individual redundant sub-pixel point slightly becomes big, the power of corresponding unit area luminescent material reduces, and further extends the life-span of the sub-pixel point so that the life-span of sub-pixel point further uniforms.

Description

It is a kind of that there is the LED array display part for sharing individual redundant sub-pixel point
Technical field
The invention belongs to display technology field, is related to a kind of LED array of display individual redundant sub-pixel point alignment technology, especially relates to A kind of and LED array display part with shared individual redundant sub-pixel point.
Background technology
LED gets most of the attention the advantages that long lifespan because with efficient, energy-conservation, size is small, extensive in display field at present Using, such as outdoor large area LED array display screen, small area OLED ultrathin flexible display screens, micro-LED array display devices It is also regarded as another frivolous and savings advantage the Display Technique of tool after OLED display screen.But regardless of Display Technique, all Exist each sub-pixels life-span differ caused by develop the color after long-term use it is inaccurate or even the problem of influence service life.
Such as OLED, its luminescent layer is mainly mixed by red fluorescence material, green light material and blue light phosphate material three are luminous, The life time decay of one of which material, will allow whole OLED pixel point failure, but organic light emission blue light phosphate material at present Life-span is too short, how to overcome this problem, turns into the challenge that practitioner must face.
A solution is shown using white light OLED combination color filter film：The OLED to emit white light is prepared first Device, then obtains three primary colours by color filter film, and recombinant three primary colours realize colored display.But transmission is made using this technology Light loss is up to 2/3rds caused by color filter film so that display efficiency substantially reduces.Another solution is to use Particular topology, in the case where red and green sub-pixels point area is constant, increase the area of blue subpixels point, so that The blue pixel luminous power of unit area reduces, delaying aging speed.But this scheme is due to blue subpixels point area mistake It is big make it that screen colour cast is serious after using a period of time, further, since single pixel point area is excessive, under display resolution is obvious Drop.
Before thoroughly solving the problems, such as that each sub-pixels point life-span differs, the efficient layout of array of display is still practitioner The emphasis of concern.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of LED array display for having and sharing individual redundant sub-pixel point Part, LED array display part efficient layout can be enable.
In order to solve the above technical problems, the technical scheme is that：It is a kind of that there is the LED battle arrays for sharing individual redundant sub-pixel point Row display device, its innovative point are：The LED array display part includes the red, green, blue sub-pixel point of dense arrangement, its In, a red sub-pixel point, a green sub-pixels point and a blue subpixels point form a light emitting pixel unit；If A dry light emitting pixel unit surrounds an individual redundant sub-pixel point, forms a pixel-array unit；And then several pixel battle arrays Column unit is densely arranged to form LED array display part.
Further, in the red sub-pixel point, green sub-pixels point and blue subpixels point, two longer lifes The area of sub-pixel point is identical, and more short-life sub-pixel point is identical with the area of individual redundant sub-pixel point, and individual redundant sub-pixel point Area be more than two longer lifes sub-pixel point area.
Wherein, in the red sub-pixel point, green sub-pixels point and blue subpixels point, if the sub-pixel of two colors The point life-span is all shorter, and the sub-pixel point that the life-span can also be made most short is identical with the sub-pixel point area of longest-lived, long in the life-span Sub-pixel point area it is maximum, and the individual redundant sub-pixel point sub-pixel point most short to the life-span compensates, and further homogenization is each The service life of sub-pixel.
Further, with >=0.1 μm between the red sub-pixel point, green sub-pixels point and blue subpixels point Spacing.
Wherein, when detect in a certain pixel-array unit some compared with short life sub-pixel point failure or brightness significantly During reduction, the individual redundant sub-pixel point in the pixel-array unit is accessed into display driver circuit, original sub-pixel point is carried out Replace or compensation is luminous.
In the technology of the present invention, when judging the abnormal sub-pixel point position of the array of display, one is shown using the device Standard picture, the display image of itself and fault-free array of display is contrasted, faulty sub-pixel point position is determined, so as to disconnect The adjacent individual redundant sub-pixel point of driving is transferred in the driving of corresponding sub-pixel point；This process both can be that drive circuit voluntarily samples Contrast fusing is connected, again can be with the manual inspection operation of operator.
The advantage of the invention is that：The present invention has the LED array display part for sharing individual redundant sub-pixel point, by some Individual pixel cell, both can be sub to the exception of surrounding by individual redundant sub-pixel point around the arrangement mode of an individual redundant sub-pixel point Compensating to extend the life-span of array of display for pixel, again can drop influence of the individual redundant sub-pixel point to array of display resolution ratio To minimum；Further, since the area compared with short life sub-pixel point and individual redundant sub-pixel point slightly becomes big, corresponding unit area hair The power of luminescent material reduces, and further extends the life-span of the sub-pixel point so that and the life-span of sub-pixel point further uniforms, So as to effectively solve the problems, such as LED array of display long-term use colour casts.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
