Description
Technical field
The utility model relates to a kind of mounting panel, particularly relates to a kind of prefabricated mounting panel of the OLED of being applicable to display screen seamless joint method.
Background technology
OLED(Organic Light Emitting Diode, Chinese Organic Light Emitting Diode) Display Technique, refer to organic semiconducting materials and luminous organic material under the driving of electric field, by carrier injection and the compound independently luminous technology that causes.Compare the display (LCD, PDP) of present main flow, that the OLED display has is frivolous (only for LCD 1/3), all solid state, simple in structure, contrast is high, active illuminating, low in energy consumption, fast response time, working range are wide, without visual angle restriction, the plurality of advantages such as softness is flexible, processing technology is simple, simultaneously, because but OLED has large tracts of land film forming, low in energy consumption and other good characteristics, therefore have very strong competitiveness, will become main flow flat panel display of future generation.OLED or a kind of desirable planar light source,
Present independent substrate show realize under the manufacture craft in large-sized OLED, have the problems such as yields extremely low (about 40%), cost of manufacture be high.Can realize the breakthrough of OLED size by the splicing of a plurality of small size OLED display floaters, at present to this existing trial, but technique is not yet ripe.Simultaneously, the OLED splicing has the many merits such as high-resolution, power saving, modularization.How to reduce OLED piece splicing seam observability, reduce cost, improve display effect and simplify technique, outline when becoming in the industry new product designs.Therefore, need to overcome the splicing that above-mentioned difficulties is improved OLED, the core technology original for the OLED splicing lays the first stone.
For example, application number is CN201080040046.6, publication number is the Chinese patent " tiled display with overlapping flexible base, board " of CN102484123A, a kind of splicing display device is disclosed, described splicing display device comprises: the identical overlapping displaying block of transparent part at least five functions of two-dimensional arrangements, each displaying block comprises the pixel that is arranged in the two-dimensional array, and described displaying block is arranged so that by the light transmission adjacent tiles that the pixel below the adjacent tiles is sent that is positioned in the edge of pel array.The weak point of this invention is: 1, adopt the transparent flexible substrate, because the transparent flexible substrate can be crooked arbitrarily, the thickness that stack produces between multilager base plate can be offset by the radian that is bent to form, unlikely formation thickness difference, simultaneously because the transparent flexible substrate can be crooked arbitrarily, can eliminate substrate and splice the slit that produces when bonding, but for inflexible rigid substrate, use generation can not be eliminated in the stack of meeting of the present invention between substrate thickness difference and slit, affect display effect, all be difficult to realize for the fixing of substrate and encapsulation; 2, utilization of the present invention is fixed on transparent flexible covering on the transparent flexible substrate and realizes splicing between substrate, the edge pixel district part of each piece transparent flexible substrate is blocked by clear covering, this part is evenly blocked by main edge pixel district of blocking, wherein, a part is covered by individual layer transparent flexible covering, a part is covered by two-layer covering, a part is covered by three layers of covering, the light that the each several part pixel is sent produces weakening in various degree after by the covering of the different numbers of plies, brightness is difficult to reach even on the whole, reduced display effect, although process the brightness of the pixel region that can improve the edge cover lid by software, reduce simultaneously the useful life of device; 3, the present invention is by being fixed on the splicing between the transparent flexible covering realization substrate on the transparent flexible substrate, must fix corresponding covering on each piece substrate, and partial pixel coating cover material is blocked, therefore, character to clear covering has certain requirement, clear covering must reach certain light transmission rate, has increased manufacture difficulty and cost.
Again for example, application number is CN200910038539.5, publication number is the Chinese patent " a kind of OLED mosaic display screen " of CN101587670, a kind of OLED mosaic display screen is disclosed, mainly be spliced by the soft OLED display screen of several piece or hard OLED display screen, to the splicing of soft OLED display screen be edge with every OLED display screen without image display area by the back side bending of certain angle to the OLED display screen, be by drawing wire from hard screen side to the splicing of hard OLED display screen; The present invention is by mutually being close together the matrix arrangement mode of several piece OLED display screen according to the capable N row of M, employing is stitched together several piece OLED display screen, and be fixed on the supporter, make every block of image on the OLED display screen and another piece OLED show that the image of screen display can more intactly be connected.The weak point of this invention is:
1, adopt soft OLED display screen splicing shortcoming: in the described technology to the splicing of soft OLED display screen be with the edge of every OLED display screen without image region by the back side bending of certain angle (more than or equal to 90 degree) to the OLED display screen, form bending part, then the bending part of the soft OLED display screen of each piece and the bending part of the soft OLED display screen of adjacent each piece are close to mutually, thereby are realized splicing in the direction of two dimension.To soft OLED display screen bending, easily to OLED display screen injury, reduce the product volume productive rate in the described technology, increase cost of manufacture; In the described technology to soft OLED display screen bend backward 90 the degree or greater than 90 the degree, higher to technological requirement, complex process; In the described technology kink of soft OLED display screen directly is close to splicing mutually, causes the slit that certain width is arranged between the adjacent OLED, affected integrality and the continuity of image frame, reduce image quality;
2, adopt hard OLED display screen splicing shortcoming: the splicing to hard OLED display screen in the described technology is by drawing wire from the side of hard OLED display screen, the side of the hard OLED display screen of each piece and the side of the hard OLED display screen of adjacent each piece being tied sturdy existing splicing mutually.In the described technology with arrangement of conductors in hard OLED side, need to adopt special process, complex process, cost of manufacture is high; Adjacent hard OLED has drawn wire between shielding in the described technology, causes the slit that certain width is arranged between the adjacent OLED, affects integrality and the continuity of image frame, reduces image quality; Push the wire injury between the adjacent screen in the described technology, reduce the life-span of wire.
