Definitions
- the present invention relates to the field of display technologies, and in particular, to a high resolution pixel structure and a high precision metal mask corresponding to the pixel structure.
- OLED display technology does not require backlighting.
- OLED display technology has the characteristics of spontaneous light, using a very thin organic material film layer and a glass substrate, and when a current passes, the organic material emits light.
- the luminescent layer of the OLED panel generally forms an organic luminescent component by using an organic material by a vapor deposition film forming technique through a high-precision metal mask (FMM, Fine Metal Mask) on a corresponding pixel position on the array substrate.
- FMM Fine Metal Mask
- the best way to colorize the picture is the side-by-side approach.
- Side by side there are three sub-pixels of red, green and blue (R, Q B) in one pixel range, and each sub-pixel has independent organic light-emitting components. Since the organic light-emitting materials of the three sub-pixels of red, green and blue are different, in the manufacturing process, three different organic organic layers of red, green and blue light-emitting sub-pixels are required to be respectively deposited by the metal mask at corresponding positions. Material, then adjust the color mixing ratio of the three color combinations to produce true color. Thus, the red, green, and blue OLED elements independently emit light to form one pixel.
- the technology of making high-resolution (PPI, Pixel Per Inch) OLED screens focuses on high-precision metal masks with fine and mechanical stability.
- the key to high-definition metal masks is the arrangement of pixels and sub-pixels. .
- FIG. 1 schematically illustrates a conventional side-by-side arrangement of pixels used in an OLED panel.
- the OLED display illuminating layer is composed of a plurality of rows and columns of pixel units 100 arranged on the substrate 10.

- the corresponding metal mask is as shown in FIG.
- Fig. 2 schematically shows a metal mask used for forming one of the sub-pixels (R sub-pixels) in the pixel structure shown in Fig. 1 on an OLED display substrate. It can be understood that since the patterns of the respective sub-pixels are the same, a metal mask of the same structure can be used for forming the remaining sub-pixels (G, B).
- the metal mask includes a metal substrate 20 and a rectangular opening 200 thereon.
- the number of openings can be determined according to the number of pixels required for the resolution of the OLED display.
- the four rows of openings 200 are shown in simplified form in FIG. Two adjacent
- the portion 201 between the ports 200 forms a metal strip of the metal substrate 20 that is not opened.
- the metal mask is opened in such a manner that, as shown in FIG. 1, all the sub-pixels (for example, R sub-pixels) in the same column in the OLED panel share the same opening 200. Therefore, the opening 200 of the metal mask is longer in length. As the size of the display increases, the length of the opening of the metal mask also needs to increase.
- the opening manner of the metal mask is to increase the metal bridge in the Slit opening mode corresponding to the opening 200 as shown in FIG. 2 corresponding to the position between the sub-pixels as shown in FIG. Bridge 301, and connecting adjacent metal strips, changes one strip opening 200 as shown in FIG. 2 into a plurality of opening units 300 corresponding to the sub-pixel structure as shown in FIG.

- the green sub-pixels are arranged on one side of the blue sub-pixels and arranged along the long sides thereof at positions on the upper and lower sides of the long sides of the blue sub-pixels.

- a pixel structure is arranged such that the opening pitch of the red and green sub-pixels corresponding to the metal mask (as shown in FIG. 5 and FIG. 6) is relatively large, and high-resolution display can be realized to a certain extent.
- the blue sub-pixels in the pixel array are still arranged in a straight line as shown in FIG. 1, so that the corresponding metal mask must use the aforementioned Slit or the aforementioned Slot opening manner (as shown in FIG. 7). Therefore, due to the defects of the Slit and Slot opening modes as described above, the opening manner of the blue metal mask (B mask) in the pixel array arrangement mode shown in FIG. 4 seriously affects the sub-pixel aperture ratio and resolution.

- the two pixel unit groups are arranged in the horizontal direction by a second distance range arrangement, as shown in FIG. 13(c), so that the same sub-pixels of the adjacent two rows are misaligned in the horizontal direction.
- the distance between the distances of the same sub-pixels is enlarged, thereby realizing corresponding corresponding metal mask plates when manufacturing the pixel structure.
- the distance between the openings of the sub-pixels enables the manufacture of a high-resolution organic light-emitting display.
- Figure 14 (a) - Figure 14 (c) shows a pixel structure 80A-80C in accordance with a third embodiment of the present invention. As shown, the pixel units in each row can use the Side-by-side arrangement.
- Figure 14 (a) shows the pixel structure in which the sub-pixels in the pixel units in the odd-numbered rows and the even-numbered rows are arranged in the same order.
- the pixel unit groups of the even rows are shifted in the horizontal direction by a distance arrangement with respect to the odd row pixel unit groups.
- the distance of translation is such that the same sub-pixels between adjacent two rows are misaligned, the principle of which is similar to that of the first embodiment.
- 14(b) shows that the arrangement of the sub-pixels in the pixel unit 500A in the pixel unit group of the odd-numbered rows is different from the order of the sub-pixels of the pixel units in the pixel unit group 501A of the even-numbered rows. structure.
- the arrangement order of the sub-pixels in the pixel unit of the odd-numbered rows is B, R, G
- the arrangement order of the sub-pixels in the pixel units of the even-numbered rows is R, G, B or G, B, R.
- the boundaries of the pixel units in the pixel unit group of the odd-numbered rows and the even-numbered rows can be aligned in the left-right direction, so that the pixel units of the odd-numbered rows and the even-numbered rows are aligned in the left and right edge portions of the display screen, thereby better By using the area of the display screen, a better display effect is achieved.
- the phase can be formed.
- the structure in which the same sub-pixels of two adjacent rows are misaligned realizes the strength of the reinforced metal mask described in the foregoing embodiments and is suitable for the effect of manufacturing a high-resolution display screen.
- the regular arrangement structure makes the corresponding manufacturing It is easier to drive the TFT backplane and design the corresponding driver circuit.
- the pixel arrangement of odd and even rows is irregular or arranged in a complicated pattern, a complicated TFT backplane design and a complicated drive circuit design are required to display the desired image.
- the red sub-pixel R and the green sub-pixel G in the odd-numbered row pixel unit group pixel unit and the red sub-pixel R and the green sub-pixel G in the corresponding pixel unit in the even-numbered row in FIG. 14(b) Set to be shorter than the length of the blue sub-pixel B (not shown).
- Figure 14 (c) shows the pixel structure in which the even-numbered rows of pixel cell groups are shifted by a distance in the horizontal direction based on the pixel cell structure of Figure 14 (b).
- the present invention also provides an organic light emitting display panel using all of the above pixel structures.
- the distance can be shifted to the left by a distance or to the right by a distance, and the range of the translation is such that the sub-pixels between the adjacent two rows are misaligned.
- the opening effect of the metal mask of the present invention can also be achieved by the arrangement as shown in FIG.
