Below will carry out detailed explanation to manufacturing approach collocation Fig. 2 A to Fig. 2 C of electrophoretic display panel.
Fig. 2 A to Fig. 2 C is the manufacturing approach synoptic diagram of the electrophoretic display panel of one embodiment of the invention.At first, please with reference to Fig. 2 A, on a substrate 200, form a pixel defining layer 210, wherein pixel defining layer 210 has a plurality of little glass of 210a.Then, in little glass of 210a of part, form above-mentioned first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130.It should be noted that; First sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130 for example are through ink jet printing (Ink-Jet Printing; IJP) mode is made, and the relative position of first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130 can be with reference to Figure 1A.
In the present embodiment; The formation method of first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130 for example is earlier a red electrophoresis liquid 112 and the white charged particles 114 that are doped in the red electrophoresis liquid 112 to be injected little glass of 210a of parts; Then, a green electrophoresis liquid 122 and the white charged particles 124 that are doped in the green electrophoresis liquid 122 are injected little glass of 210a of parts.Afterwards, again a blue electrophoresis liquid 132 and the white charged particles 134 that are doped in the blue electrophoresis liquid 132 are injected little glass of 210a of parts.Since each first sub-pixel 110 not with second sub-pixel 120 and the 3rd sub-pixel 130 adjacency; And each second sub-pixel 120 not with the 3rd sub-pixel 130 adjacency; Therefore; Even contraposition precision deficiency appears in ink-jet printing process or the consumption of electrophoresis liquid was controlled not at that time; Red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 still are not easy to take place the problem of colour mixture each other, and the red electrophoresis liquid 112 of overflow, green electrophoresis liquid 122 or blue electrophoresis liquid 132 only can be inserted among the little glass of 210a of black electrophoresis liquid to being about to form in overflow.
It should be noted that; The present invention does not limit the formation order of first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130; Those skilled in the art can insert the electrophoresis liquid of different colours among the little glass of corresponding 210a according to its formation that sets order, even first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130 can form simultaneously.
Then please with reference to Fig. 2 B; Red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 are inserted little glass of corresponding 210a; And, form one first cured layer 220 with upper surface place in red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 with a ultraviolet light UV irradiation red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132.Can know that by Fig. 2 B first cured layer 220 is sealed in red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 among little glass of 210a of part.In detail; Because red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 contain the less UV cured material of proportion; Therefore when red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 during by the ultraviolet ray irradiation, the UV cured material that floats over red electrophoresis liquid 112, green electrophoresis liquid 122 and blue electrophoresis liquid 132 upper surface places just can be cured to form first cured layer 220 of a densification.
Then please with reference to Fig. 2 C, after the making of accomplishing first sub-pixel 110, second sub-pixel 120 and the 3rd sub-pixel 130, then a plurality of white sub-pixels 140 of formation in part this said little glass of 210a.In the present embodiment, the formation method of white sub-pixels 140 for example is earlier black electrophoresis liquid 142 and the white charged particles 144 that are doped in the black electrophoresis liquid 142 to be injected remaining little glass of 210a.Then, shine black electrophoresis liquid 142 to form one second cured layer 230 with a ultraviolet light UV.Can know that by Fig. 2 C second cured layer 230 is sealed in black electrophoresis liquid 142 among the little glass of 210a.In detail; Because black electrophoresis liquid 142 contains the less UV cured material of proportion; Therefore when black electrophoresis liquid 142 was shone by ultraviolet ray, the UV cured material that floats over black electrophoresis liquid 142 upper surface places just can be cured to form second cured layer 230 of a densification.
The red electrophoresis liquid 112 of overflow, green electrophoresis liquid 122 or blue electrophoresis liquid 132 can be blended in the black electrophoresis liquid 142, but the red electrophoresis liquid 112 of these overflows, green electrophoresis liquid 122 or blue electrophoresis liquid 132 are little for the display quality influence of white sub-pixels 140.
[second embodiment]
Fig. 3 A and Fig. 3 B are the schematic top plan view of the electrophoretic display panel of second embodiment of the invention.Please with reference to Fig. 3 A and Fig. 3 B; In the present embodiment; Each first sub-pixel 110 only with white sub-pixels 140 adjacency; And each first sub-pixel 110, each second sub-pixel 120, each the 3rd sub-pixel 130 and each white sub-pixels 140 are all the rectangle sub-pixel, and each first sub-pixel 110 and 4 white sub-pixels adjacency.Can know that by Fig. 3 A and Fig. 3 B first sub-pixel 110, second sub-pixel 120, the 3rd sub-pixel 130 and white sub-pixels 140 for example are all square sub-pixel.
Shown in Fig. 3 A, the first above-mentioned sub-pixel 110 is arranged in multirow with the white sub-pixels 140 of part, and second sub-pixel 120 is arranged in multirow with white sub-pixels 140 partly, and the white sub-pixels 140 of the 3rd sub-pixel 130 and part is arranged in multirow.
Shown in Fig. 3 B, the first above-mentioned sub-pixel 110 is arranged in multiple row with the white sub-pixels 140 of part, and second sub-pixel 120 is arranged in multiple row with white sub-pixels 140 partly, and the white sub-pixels 140 of the 3rd sub-pixel 130 and part is arranged in multiple row.
[the 3rd embodiment]
Fig. 4 A and Fig. 4 B are the schematic top plan view of the electrophoretic display panel of third embodiment of the invention.Please with reference to Fig. 4 A and Fig. 4 B, in the present embodiment, each first sub-pixel 110 only with other first sub-pixels 110 and white sub-pixels 140 adjacency, and each first sub-pixel 110 and 2 white sub-pixels 140 and 2 other first sub-pixel, 110 adjacency.
Shown in Fig. 4 A, the first above-mentioned sub-pixel 110 is arranged in multirow, and second sub-pixel 120 is arranged in multirow, and the 3rd sub-pixel 130 is arranged in multirow, and white sub-pixels 140 is arranged in multirow.
Shown in Fig. 4 B, the first above-mentioned sub-pixel 110 is arranged in multiple row, and second sub-pixel 120 is arranged in multiple row, and the 3rd sub-pixel 130 is arranged in multiple row, and white sub-pixels 140 is arranged in multiple row.
It should be noted that the arrangement of subpixels mode that reaches described in the aforesaid embodiment can be applied in pliability electrophoretic display panel and the non-pliability electrophoretic display panel, the present invention does not limit the field of its application.
Since first sub-pixel in the electrophoretic display panel of the present invention only with the white sub-pixels adjacency; Or only with other first sub-pixels and white sub-pixels adjacency; Therefore electrophoretic display panel of the present invention is difficult for having the problem of electrophoresis liquid colour mixture, has better display quality.
