The utility model discloses use blue and yellow emitting pixel of FMM coating by vaporization, convert yellow emitting pixel to green glow and ruddiness with the light filtering mode again, can enough improve FMM coating by vaporization emitting pixel's yield, can guarantee again that blue chromatic light's efficiency does not receive the loss.
Referring to fig. 6, the utility model provides a manufacturing process of AMOLED display panel can include:
1) and manufacturing a back plate circuit and an anode on the glass substrate.
This step may be performed by fabricating a backplane circuit and an anode on a glass substrate according to a conventional LTPS (Low Temperature polysilicon) process.
2) Performing a vapor deposition process.
The organic light-emitting material can be evaporated on the back plate according to a conventional OLED process, wherein the functional layer and the cathode can be evaporated by using a CMM (Common Metal Mask), and the light-emitting layer can be evaporated by using an FMM.
Referring to fig. 6, the backplane may be a TFT backplane 50. The functional layer may include a hole injection layer, a hole transport layer, a resistance blocking layer, a hole blocking layer, an electron transport layer, an electron injection layer, and the like. In general, CMM is a mask plate for vapor deposition, which has a large opening, can cover the entire AA (active Area, displayable Area), and is required to have low accuracy. The FMM is used as a mask plate for evaporation, has small openings, only covers the light-emitting pixels, and is required to have high precision.
3) Two light emitting layer structures are provided.
The traditional mode of OLED is equipped with the three luminescent layer of RGB, the utility model discloses an AMOLED's luminescent layer structure only is equipped with two luminescent layers. Referring to fig. 6, one of the blue light emitting layers is formed as a blue light emitting pixel (B)201 by FMM evaporation. The other is a yellow light-emitting layer, and a yellow light-emitting pixel (Y1)211 and a yellow light-emitting pixel (Y2)212, namely two yellow light-emitting pixels of the same color of Y1 and Y2, are formed by evaporation of the same FMM. The blue light emitting layer can be made of the existing material, the yellow light emitting layer can be made of the yellow phosphorescent light emitting material, and the functional layer can be made of the existing material.
Wherein, yellow FMM opening sets up and is bigger than traditional opening, and yellow FMM opening includes two emitting pixel, can set up to 1.5 ~ 2 times bigger than traditional, because the opening is big, the preparation is easy, and is with low costs, and the yield also can be high.
In the traditional technical scheme, three kinds of material coating by vaporization of RGB, have certain clearance distance each other, about 20 ~ 25um approximately, the colour-mixing defect (colour-mixing, two kinds of luminescent material have plated a luminescent layer promptly, and the colour can be just) has appeared for a short time. While the Y1 and Y2 pixels are the same color, this problem does not exist with a single FMM, so that the gap can be reduced, for example, to less than 5 um. Since the gap between the Y1 and Y2 pixels is reduced and the area left for the blue pixel is increased, the blue pixel aperture ratio is increased and the lifetime of the blue pixel is increased considerably. In addition, the blue light-emitting pixel also has the advantages of large opening, easy manufacture, low cost, high yield and the like.
The Y1 and Y2 pixels are formed by vapor deposition through the same FMM opening, and each pixel has an area including two pixels. That is, the FMM of Y1 and Y2 is the same as the manufacturing process except that two pixels are divided by PDL (Pixel definition layer) and an anode, and finally the Y1 Pixel is changed to R red light and the Y2 Pixel is changed to G green light by a color filter. Since the FMM of the Y1 and Y2 pixels is the same as the manufacturing process, the production efficiency can be improved.
4) And arranging a filter layer with different colors, a blank position and a black shading film on the color filter.
Referring to fig. 6, a color filter 30 is formed on the CF cover 40 at a corresponding position, the color filter 30 forms a red filter layer 302 at a position corresponding to a part of the yellow light emitting layer, for example, a position corresponding to a yellow light emitting pixel (Y1)211, forms a green filter layer 303 at a position corresponding to a part of the yellow light emitting pixel (Y2)212, and fills the middle with a BM (Black Membrane) 304. The color filter 30 is provided with a blank position 301 at a position corresponding to the blue light emitting layer. The red filter layer and the green filter layer can be made of the existing manufacturing materials.
That is, the color filter 30 of the present invention is provided with a first color filter layer 302, a second color filter layer 303, a blank position 301, and a black light shielding film (BM) 304; the first color filter layer 302 may correspond to all or part of the yellow light-emitting pixel (Y1)211, the second color filter layer 303 may correspond to all or part of the yellow light-emitting pixel (Y2)212, the blank position 301 may correspond to all or part of the blue light-emitting pixel (B)201, and the black light-shielding film (BM)304 may correspond to the remaining other positions. The area of Y1 can be the same as or slightly larger than that of R, the actual light-emitting area can be determined by the size of the filter, and the positions are vertically corresponding; the area and positional relationship of Y2 and G are also similar.
5) And attaching and packaging the glass substrate and the CF cover plate.
The glass substrate and the CF cover plate are attached and packaged. Wherein the blue light emitting pixel 301 corresponds to a Color-Filter blank position 301, and the yellow light emitting layer corresponds to R (red Filter) 301 and G (green Filter) 303 portions of the Color-Filter.
6) The driving backplane circuit emits blue light, red light and green light.
When the backboard circuit is driven, the blue light-emitting pixel emits light and emits blue light through the completely transparent cover plate; the first yellow pixel emits light which is converted into red light through an R color-filter (a red filter layer of a color filter) and emits the red light; the second yellow pixel light is converted into green light through a G color-filter (green filter of a color filter) and emitted.
It can be found that the technical scheme of the utility model has following effect:
1) because the utility model discloses an AMOLED luminescent layer structure has only two luminescent layers, has lacked one FMM coating by vaporization processing procedure, and the colour mixture that consequently FMM arouses and some defects have reduced.
2) Because the utility model discloses an AMOLED luminescent layer structure only has two luminescent layers, and RG is formed by two Y light emitting pixel conversion, and the clearance gap in the middle of two Y light emitting pixel just can be done very little, and the space of reserving for blue light emitting pixel is bigger, and blue light emitting pixel area does greatly, and luminance and life-span all can become good.
3) The utility model discloses a Y + R color-filter mode and Y + G color-filter mode are applied to AMOLED, are different from traditional W + color-filter mode.
4) Utilize the utility model discloses a scheme, Y light emitting pixel's efficiency can be very high, can reach more than 100cd/A (luminance value under the unit current density), and the efficiency after converting RG (ruddiness and green glow) is also very high, and the efficiency of converting R (ruddiness) has more than 30cd/A, and the efficiency of converting G (green glow) can reach more than 70 cd/A.
The technical solution according to the present invention has been described in detail above with reference to the accompanying drawings.
Those of ordinary skill in the art will understand that: the above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
