Abstract

PURPOSE:To enlarge a light emitting area, to realize high brightness and to prevent the degradation of a picture quality by arranging light emitting picture elements so that a distance between the picture elements within sets is shorter than that between the sets in a display part, and making the distance between the picture elements apparently approach to that between the sets with an enlarging element in an enlarging part. CONSTITUTION:In a display part 1, for example, four light emitting picture elements 2 are made to be one set, the construction ratio of R:G:B picture elements is made to be 1:2:1, and the ratio of a distance P1 between the picture elements to a distance P2 between the sets is made smaller that 0.6. Then, a convex lens 5 is provided according to each light emitting picture element 2, a deviation between a center (p) of the light emitting picture element 2 and a center (r) of the convex lens 5 is made to be only by DELTAP, and the center (r) of the convex lens 5 is made close to the side of the adjacent picture elements within the sets. At that time, DELTAP or the magnification of the convex lens 5 or the like is set appropriately so that P1/P2=1 can apparently be obtained. Thus, the best use of the characteristic of the high brightness due to the enlargement of the picture element area is made, and an adverse influence of the degradation of the picture quality due to an enequal pitch can be reduced.

的なテレビ画像を認識できる。Next, the operation will be explained. Each light emitting pixel 21 is driven by a driving section (not shown) and emits light of each color. Here, the light emitting pixels 21 are generally arranged at equal intervals. Let this interval (space width) be P22. In the case of a large screen display, several display sections 11 shown in FIG. 3 may be arranged to form one large screen display section. In this case, in order to keep the light-emitting pixels 21 equally spaced, the width P22 of the space must be set to the distance P2,02 (peripheral distance) between the light-emitting pixels 21 existing at the outermost periphery and the edge of the display section 11. More than double the length is required. Further, in a large screen display, the luminance of each light emitting pixel 21 is controlled so as to be proportional to the amplitude of the television signal. Here, the light-emitting pixels 21 are arranged discretely at predetermined intervals, but when a viewer looks at the display unit 11 from an appropriate distance, a continuous television image can be recognized.

ながって画質が低下する原因となる。Now, in order to increase the resolution of the large screen display,
It is necessary to increase the number of light emitting pixels 21 per unit area. That is, it is necessary to shorten the distance P21 between the centers of the light emitting pixels 21. However, as mentioned above, the width of the space P2
2 needs to be at least twice the peripheral distance P25, and the peripheral distance P23 is the thickness of the wall of the display section 11, and there is a limit to how thin it can be. Therefore, in order to increase the number of light emitting pixels 21 per unit area, it is necessary to reduce the size of the light emitting pixels 21. In other words, the higher the resolution of the display, the smaller the light emitting area ratio becomes. This situation results in emphasizing the discontinuity in the arrangement of the discrete light emitting pixels 21, leading to a grainy appearance in the displayed television image and causing deterioration in image quality.

It is conceivable to provide an enlarged section 41 on the front surface of the display section 11 as shown in FIG. For example, a convex lens 51 is provided corresponding to each light emitting pixel 21, and the center of the light emitting pixel 21 and the convex lens 5
1 and the apparent light emitting area ratio is increased to improve image quality. In this case, the fourth
As shown in Figure CB), the light emitting pixel 2 is

Also in this case, for the reason mentioned above, the width P22 of the space needs to be at least twice as long as the distance P25 of the periphery. Therefore, as the resolution increases, the area of the light emitting pixel 20 becomes smaller, as shown in FIG. 5(B). Therefore, the brightness decreases.

There is a method in which pixels are set as one set, and the distance P1 between pixels within the set is smaller than the distance P2 between the adjacent sets. This display unit 1 is shown in Japanese Utility Model Application Publication No. 174377/1983. In this case, the distance P22 between a certain group and the adjacent group is
By making the distance between the light emitting pixels 2 in a group smaller than the distance between the light emitting pixels 2 in the group and the light emitting pixels 2 in the adjacent group while making the distance P2302 times or more of the peripheral part, The area of the light emitting pixel 20 is larger than that shown in FIG. 5(B). When the area of the light-emitting pixels 20 is enlarged with four pixels as one set in this way, the arrangement of each light-emitting pixel 2 becomes a so-called unequal pitch arrangement in which every two pixels are biased in the row and column directions.

It is equal when 1/P2-1. In other words, the light emitting pixels are arranged at equal pitches as shown in FIG. Also,
In the case shown in FIG. 6, P1/P2=about 0.7, and in the case shown in FIG. 7, pl/p2<0.6.

Therefore, in the case shown in Fig. 6, the effect of improving brightness is more dominant than the deterioration of image quality and is suitable for practical use, but in the case shown in Fig. 7, although the effect of improving brightness is greater, it is not suitable for practical use. Not.

、表示部１１の寿命が低下するなどの課題があった。Since the conventional display device is configured as described above, if the apparent light emitting area is expanded by the enlarger 41 while the light emitting pixels 21 are kept at the same pitch, the actual light emitting area is not expanded. High brightness cannot be achieved, and it cannot be used in bright environments where people gather, such as stations and airports.If you dare to increase brightness, you will end up using it in an unreasonable manner, such as giving high energy to the light emitting pixels 21. Therefore, there was a problem that the life of the display section 11 was shortened.

大きくすることはできないという課題があった。In addition, in the case where the arrangement of the light emitting pixels 2 is arranged in an uneven manner,
As the area of the light-emitting pixel 2 is increased in order to increase the brightness, the image quality deteriorates, and there is a problem in that the area ratio cannot be increased beyond a certain level.

る。Next, the operation will be explained. In the display section 1, the light emitting pixels 2 are arranged, for example, as shown in FIG. In the arrangement shown in FIG. 7, the composition ratio of 8 pixels, 0 pixel, and 8 pixels is 1:2:1 with 4 light-emitting pixels 2 as one set, and the inter-pixel distance P1 and the inter-pair distance P2 The ratio is smaller than 0.6. If they are arranged in this way, as already mentioned, the image quality will deteriorate significantly. However, in this case,
A convex lens 5 is provided corresponding to each light emitting pixel 2, and as shown in FIG. 1(A), the center p of the light emitting pixel 2 and the center r of the convex lens 5 are shifted by ΔP, and The center r of 5 is closer to the adjacent pixel side in the boat. By arranging the convex lenses 5 in this manner, the light emitted from each light-emitting pixel 2 is magnified by the adjacent pair. By appropriately setting ΔP, the 50 magnification of the convex lens, etc., it is possible to make P1/P2=1 in appearance. Therefore, as shown in FIG. 1(B), when viewing the enlarged section 4 from the front, p1/p2 appears to be closer to 1 than the actual value on the display section 1. As a result, it is possible to reduce the negative effect of image quality deterioration due to uneven pitches while taking advantage of the feature of high brightness due to the expansion of the pixel area. Furthermore, in terms of expanding the light emitting area, it is possible to obtain an apparently higher magnification ratio than before.

Since it is configured to be close to the inter-set distance, it is possible to increase the luminance by expanding the light emitting area, and also to prevent deterioration in image quality and provide a smooth image while having a long life.
