Abstract

TThe present invention relates to an LED arrangement method of color LED display to increase the visual image resolution of display, wherein each LED is set as an unit pixel, and the display is formed by arranging the adjacent red, blue, and green color LEDs in 1:1:2 ratio, so that the four comers of each LED unit can form the pixel center when they are adjacent to LEDs with different colors., namely, the distance of each adjacent pixel center is equal to the spacing between the unit pixel and LED. By using the arranging method, it is able to not only shorten the display distance of pixel, but also achieve the effect of increasing the image resolution.

Description

200409066 V. Description of the invention (l) [Technical field to which the invention belongs] The present invention provides a "1 {: 1) arrangement method for a color LED display" which can improve the effect of image resolution. [Previous technology] The eye shovel LED display has color and monochrome design. Press one-one ·. ~ Team "

LpD displays are mostly used in large dynamic signboards with changing patterns or text descriptions, such as commercial advertising displays, weather reports and icons, news reports, and 'monochrome LED displays are only used for similar marquees. Simple text or animation display, no matter what kind of LED display, it can only be used for outdoor signage, for people to view from a distance, but because of its poor image resolution, it can not be viewed at close range. . The structure of the shirt color LED display is composed of a plurality of unit pixels 10, and each unit pixel 10 includes R, G, β (red, green, blue) f different color LED units. The synthesis, as shown in the first picture, is to use the effect of people's long-distance parallax, and each pixel can be changed into different colors by different colors R, G, β (red, green, blue) LED brightness. White, Ϊ, f: orange, *, red, blue, green, purple, etc., with different shades of color = dagger = the reason why its resolution is not good is because it is composed of three groups: a unit painting Element 10, after encapsulation, is about ～~ square, each single heart distance w 'is equivalent to—unit pixel after encapsulation = union; early element pixel 10 only requires color rendering, so the arrangement of its LEDs There is no certain position and distance, y3, y4 'The distance yl ”5 of the similar LEDs of each unit 佥 sound 10 is also not necessarily' and —

V. Description of the invention (2) The required screen or font can be formed into a cylinder, and after packaging, each LED is visualized with the LED in the adjacent unit pixel 10, and a considerable distance will be generated. The resolution is poor, and the development effect is relatively rough. It must be viewed from a long distance to be able to see the content of the overall pattern. Visually, the screen is not only meticulous, but the lines seem to have continuous rhombus. There is also a way that a unit pixel 10 is provided with four LEDs. As shown in the second figure, although it can have the variability of increasing the color of the unit pixel 10, it still cannot exceed the aforementioned deficiency. [Summary of the invention] The inventor has been engaged in optical research for many years, 'recognizing that the traditional display is still σ is a thinking mode based on the design of the basic unit pixel display effect, so whether three or four or more LEDs focus on one The unit pixels are just colorless ... The color is not changeable, and it does not effectively change the overall development effect. The difference in resolution is because the unit area of the unit pixels is large, and the distance between adjacent units. Wideness is the main sticking point. ”To increase the resolution of the display, you must reduce the pixel size of the unit.“ The change, there are still at least three LEDs in width and package size ... ^, if you start with changing the size of the LED, this will be another item This process is time-consuming, labor-intensive, and is not in line with economic principles and benefits. Therefore, from = its imaging effect and resolution, it must go beyond its traditional thinking. If you want to change the principle of the Ϊ 立 基 * ί structure, m takes time and money to achieve the expected results, and if you do not delay the economic principle, and do not change the nature of the display = principle, it will be conducive to the development of R & D. This structure and original

200409066 V. Description of the invention (3) Furthermore, the inventor abandoned the traditional mode of thinking and thought in the direction of the colored columns. Therefore, it was found that if the individual L2: L: painting element is used, then the unit painting is greatly reduced. The width of the element can also separate the early distance of each LED and reduce the day-to-day center distance of the unit, and it can: add its resolution. = This also needs to take into account that each day element center will have * same color clothing to form a unit of development, so if you use each LED as a unit to draw ^ 'Pixel will be located in the four color LEDs In addition, the four corners of the mother LED will also become the daylight center of the four adjacent ^^, and the fate = two will consider the visual effect of human color, and human vision will be the greenest ^ f 'Therefore, adjacent color LEDs use i: 丨: 2's ratio of red, blue, and green' as a basic unit pixel unit, and all LEDs become unit pixels: ' Become a pixel center, and can be combined with; Zhou Lian is formed into a united day pixel unit, and Equal to the unit, so the imaging unit is small, and the combined imaging with other adjacent iLEI) imaging will have halo, but because its unit is small, the imaging pattern is large, so it is not out of place. In some cases, both contingent and small proportions do not cause all the shadows. This is another inventive goal of the present invention, "the method for arranging LEDs of a color LED display," to achieve a clever resolution. [Embodiment]: Invent the "color LED display iLED arrangement method", which can be combined with the picture "Er Ming ', whose basic unit is 1: 1, 2: R, B, G are ▲, green four-color color LED A set of pixel units 20, because of green

Page 6, 200409066, description of the invention (4) Because the visual sensitivity of people is relatively south, it is necessary to have two green LEDs in every four LEDs, so the arrangement method is to alternate left and right horizontally in every other row. Green LEDs are placed, and red and blue are located between adjacent horizontal green rows, staggered back and forth with each other, and each LEI) is also a unit pixel 10, and at least red and green around each LED And blue LEIs) are adjacent to each other, and there are ^ 1 red, blue, and green LEDs that are combined into a set of pixel units 20, and the pixel center u of each set of pixel units 20 is For the four angles of each LED, we will simply give four joint pixel units 20 for illustration. The combination of nine adjacent LEDs obtained by analyzing the enlarged view as shown in c is taken as an example. , The four LEDs are composed of G, R, B, G, that is, the green, red, blue, and green unit pixels 10 are composed of the connected pixel unit 20, and the pixel center 1 la is located between the four, The four LEDs in the C2 picture are R, g, and Bg. The unit is composed of 3 red, 1 red, Ϊ, and f unit pixels.

LΓ b is located between the four LEDs Ϊ H 2G in the C3 picture, and its pixel unit UC is also four of them: the four LEDs in the 4 picture are β, G, R, and G to form the meta pixel i 〇 united set of pixel units 20. This is possible because of each M element center 11. It has the function of joint set display. Although 70 pixels and 10 pixel units of 20 pixels each have a small area of <3 ~ 4mm> ^ Here, the color halo produced by the unit, but because of the unit painting results, and because the unit day Xin = /, Does not affect the display effect of the overall display, there is no traditional reason, can be directly arranged for the UD, and there is no hue around the unit pixels caused by the structure,

200409066 Fifth, the description of the invention (5) and the visual sense of space, so will increase the viewing distance of the displayed picture with the same traditional display, compared with the present invention ^, pre-practice is much higher than the traditional solution display, or Under close-up viewing, the continuous and non-interlaced display of $ 1 can also achieve clear effects. The continuous display is also more realistic and consistent. In addition, because of the small size of the lipstick-color LED unit, its design, the gap T adjacent to each other can be close, or it can show a certain effect ^ ^ ^ ^ ^ ^ ^ ^ . Away from the gap T, but still not shadowing, you can directly use the required display, surface area of the LED arrangement, or package with a certain number of LEDs as a unit, with the combination of the day and time of the indicator, such as ^: ^: 2 The red, bass, _ ,,, ', at least four-groups of the combined day element unit 20, or the ratio of the green ratio into a blue combination, or so that the mother LED can be adjacent to it "1) It is 1 and the green LEDs are arranged in proportion to form a complete set. One is two, the other is a group of several Chinese paintings, which can be easily assembled into the required display area. Comprehensive As a result, the present invention has the following advantages over the traditional method: Because it uses the mother LED as a unit of the book, Yan. · small, f 彡 I f $,% I so the distance between adjacent so it; ί Two ^ Equivalent display interval. The unit pixels adjacent to each other also generate the center of the basin due to the two LEDs being adjacent to each other, and the traditional junction ... Xin Jiaozhong &quot; can: the LEDs around it form the distance of their package Large volume = This adjacent distance is naturally poor in image effect! 200409066 V. Description of the invention (6) 3. Because LEDs are adjacent to each other, their Small size and high resolution. 4. Because it is a 1: 1 arrangement of red, blue and green adjacent to each other, it not only has high resolution but also meets our visual perception. The sensitivity of the green hue is more vivid.
