Description
Technical field
The present invention relates to the display unit of a kind of OLED display unit and employing OLED display unit, belong to display manufacturing technology field.
Background technology
Along with developing rapidly of electronics industry, and society shows improving constantly of product requirement for information, and the huge market demand has appearred in employed indoor type or the large-scale flat-panel screens products of half indoor type for Information Communication, news briefing, securities trading in field such as airport, shopping mall, Surveillance center, stadiums.As traditional technology---LED large scale display that provides large-scale information to show, integrated microelectric technique, computer technology, the information processing technology etc. are in one, with its strong chromatic stimulus, the advantage such as dynamic range is wide, brightness is high, the life-span is long, working stability is reliable, become the only selection of outdoor display application.Yet for large scale plane full color OLED indoor and half indoor application showed product, market more existed following several respects to require: 1, blank screen better effects if, and contrast is higher, pursues more perfect vision effect; 2, uniformity of luminance in the good display panel is without vision difference and splicing sense, good complanation display effect; 3, the soft warmth of color, picture effect is good; 4, the reliability and stability under varying environment are high, convenient mobile and assembling; 5, cost is more cheap, and cost performance is higher.
Because traditional LED display unit provides point light source light-emitting, the visual stimulus degree is strong, and long-time observation easily causes visual fatigue and dazzle.Simultaneously it is the seamed formation full-color display that is stitched together of employing standard display module, picture continuity poor effect, so its technology is subject to great restriction when being applied to indoor demonstration.This provides chance for other plane Display Techniques enter large scale demonstration field.
OLED is the representative of latest generation Display Technique, because it adopts organic material luminous, is again area source simultaneously, and visual effect is soft, and image quality is exquisite and have third dimension, is the substitute products of the excellent high-end display application of large scale.
But for large scale OLED display screen manufacturing technology, the display of the maximum area of at present can the monoblock substrate directly making only is 55 cun specifications, what adopt also is conventional OLED full color process technology, can't make the display screen (such as the display screen of size greater than 100 cun) of more individual specification, this causes difficulty for this technology enters large-size screen monitors demonstration market.
Mitsubishi Electric Co. disclosed a kind of technology that adopts standard display module connecting method to make large scale OLED display screen in 2009, adopt this technology, the said firm uses the panchromatic display module of standard of 96mm * 96mm, and splicing has produced the OLED display screen of 155 cun specifications.This technology has effectively been utilized OLED face luminous characteristics, has a color soft, self-luminous, and the advantage of image quality fineness has realized that OLED is presented at the breakthrough of the indoor application of large scale.
The picture element density that above-mentioned Mitsubishi is delivered be 111111 pixels/square metre, the RGB(RGB) size of the pixel cell of combination of pixels is 3mm, black matrix" ultimate range between neighbor is 1.5mm, that is to say the level that standard display module splicing seams minimum has been accomplished 1.5mm.
In the above-mentioned large scale OLED display screen manufacturing process that Mitsubishi is delivered, its contact conductor is arranged in the outside of spliced display unit, occupies certain position, thereby causes package edge wider, further causes the splicing seams distance of display module wider.
Though the above-mentioned large scale OLED display screen that Mitsubishi is delivered is described as seamless spliced, but because the restriction of standard display module packaging technology, the encapsulation limit of its neighbor combination also reaches the width of 1.5mm, this width is when closely observing, visual experience is very obvious, therefore the display precision of actual visual effect is received very big restriction, be difficult to realize reaching high definition, the fine display effect, also be simultaneously because this reason, its best observed range of the whole screen of the oversize OLED display screen that Mitsubishi is delivered will be more than 3 meters, and when only having remote observation, display just can reach preferably visual effect.
For any display unit, in order to make the better visual effect of having of display, just need to make great efforts to improve the display precision of display, reduce and reduce distance between light emitting pixel, and improve the aperture opening ratio of display.Also like this for the standard of employing display module splicing making large scale OLED display screen manufacturing technology, in order to make display screen have better visual effect, must further control and dwindle the encapsulation limit of standard display module, only in this way, just can dwindle the distance between pixel cell, make display have more clearly visual effect.
