Color filter (CF) If you look at the LCD panel with a magnifying glass, you will find what it looks like in the picture below. We know that red, blue and green are the so-called three primary colors. In other words, using these three colors, you can mix a variety of different colors. Many flat panel displays use this principle to display color. We divide the three RGB colors into three independent points, each with different grayscale changes, and then use the adjacent three RGB display points as a basic unit of display, which is pixel. That pixel can have different color changes. Then for a display screen that requires a resolution of 1024 * 768, as long as the composition of this flat panel display is 1024 * 768 pixels, this screen can be displayed correctly. In the figure, the black part between each RGB point is called Blackmatrix. It is mainly used to cover parts that do not intend to transmit light. For example, some ITO traces, or Cr / Al traces, or TFT parts. Therefore, we can see in the figure that each bright spot of RGB is not a rectangle. There is also a part hidden by the black matrix in the upper left corner. This black missing part is the location of the TFT. The figure below shows the arrangement of common color filters. Stripe (stripe) is most commonly used in OA products, that is, our common notebook computers, or desktop computers and so on. Why should this application be arranged in a strip? The reason is that most of the current software is a windowed interface. In other words, the screen content we see is composed of a large number of boxes of different sizes. The arrangement of the strips just makes the edges of these boxes look more straight, without a straight line. , It looks like it has burrs or jaggedness. But if it is applied to AV products, it will be different. Because TV signals are mostly characters, the lines of the characters are not straight, and their outlines are mostly irregular curves. Therefore, at the beginning, the AV products used mosaic arrangement (or diagonal arrangement). However, most recent AV products have been improved to use a triangular arrangement (or delta arrangement). In addition to the above arrangement, there is another arrangement, called square arrangement. It differs from the previous ones in that it does not use three points as a pixel, but four points as a pixel. The four points combine to form a square.
Outdoor Mobile LED Display description: in order to meet the requirements of all-weather performance and performance rental, outdoor LED mobile rental screen is particularly important. Its appearance makes up for the requirements that indoor LED mobile rental screen cannot achieve. Also compared with the traditional outdoor scenery, the grade is not high enough, the display content is single, affected by the environment, the wind is easy to deform, the heat is easy to change color and so on. Outdoor LED rental screen completely makes up for the shortage of traditional scenery.
Outdoor Rental Led Display features:
1. The brightness is high. In outdoor mobile performance, the brightness is required to be more than 5000cd, otherwise the screen can not be seen clearly due to the influence of sunlight. The brightness of our outdoor performance screen is above 5000cd, which can be used all day.
2. It has strong UV resistance. It can be used outdoors for a long time due to the influence of sunlight. The lamp beads do not fade, but the color is still bright and the light is slow.
3. Outdoor LED mobile rental screen, with rain proof and dust-proof grade up to IP65, rain and wind are unimpeded, and rain proof cloth is used to prevent weather and rain.
4. The cabinet body adopts die-casting aluminum box structure, with good heat dissipation performance and high levelness.
5. For large-scale outdoor performance activities, the screen body can be shaped to form the same picture and split screen picture. For example, part of the screen shows the live content of the stage personnel, part of the screen shows the live broadcast of the audience, etc.
6. Brightness adjustment: according to the requirements of the use scene, the brightness can be adjusted, which greatly meets the requirements of different occasions. We are making perfect use of it both indoors and outdoors.
Outdoor Mobile Led Display Screen structure: quick lock structure, quick disassembly. The air plug and super-v network cable between the boxes can quickly link the signals and power supply between the boxes. The box has a waterproof rubber strip structure, which is waterproof up to IP65.
Precautions: as for indoor screen, pay attention to corners during handling and disassembly, handle with care, and cover the back cover for outdoor use to avoid water flow.
