REVIEW: full color LED Display using red, green and blue LED
, each tube form of the 256 gray 16,777,216 colors. Full color LED display system, using today's latest LED technology and control technology, full-color LED display prices lower, more stable performance, lower power consumption, unit higher resolution, more realistic colors rich component systems less when the electronic components, making the failure rate.
Full color
LED Tube using red, green and blue light-emitting tube, each tube form of the 256 gray 16,777,216 colors.
Full color LED display control system of the main features:
Full color LED display system, using today's latest LED technology and control technology, the full color LED display prices lower, more stable performance, lower power consumption, unit higher resolution, more realistic colors rich composition of e-group system fewer parts, making the failure rate.
With 256 gray scale algorithm, the design used in the color change "point by point dynamic color compensation" for using pure green or yellow, and green made from the full-color LED display, LED display technology enables the display of color to maintain the original image gorgeous.
Field frequency of 240HZ scan more stable picture without flicker, in practice, with the video camera display, camera observed image is very clear, there is no synchronization scroll bar, if a TV transmission site, the display does not affect the broadcast screen picture quality.
LED components: the virtual pixel 2 red 1 pure green 1 pure blue. Real pixel 1 red 1 pure green 1 pure blue
Virtual pixel display control technology
Reuse by means of pixel control technology, the display image, the same number of points than the actual pixel display four times the clarity improved, cost performance is very high. Virtual pixel screen on the actual pixel corresponding to 1 / 4 area, the image can be displayed the same effect, is the latest LED technology and control theory.
A. LED display pixel decomposition principle
LED pixel decomposition (also known as virtual pixels) technology is the adoption of LED multiplexing technology, the same LED light tube, LED light tubes can be used adjacent to 4 combined (down, down, left, right combination, see legend), so use the same LED light tube, can be expressed more pixels.
B, LED display pixel decomposition analysis
Pixel display and a virtual reality display of the display pixel differences as follows:
LED LED arranged in different ways; real pixel display in red, blue and green LED (trichromatic) real close to each other to form a pixel by pixel constitute a solid dot matrix display; virtual pixel display in red, blue and green LED equidistant uniform distribution, each LED light tube to form a virtual pixels.
Each virtual pixel LED display LED (virtual pixel) are the same around the three primary colors
LED Lighting pixels, in the amount of LED light tubes under the same virtual pixel display than the real three-color pixel display increased four times the pixels. As a result of pixel multiplexing methods, improving the efficiency of the display point of the display, virtual pixel display in the display image, the same number of points than the actual pixel display four times the clarity improved
Virtual pixel monochrome display text in the display, because the display can not be used between adjacent pixels, thus indicating ability to distinguish the real back to its corresponding pixel display. For example: 4mm spacing virtual pixel screen, the display text is equivalent to the real 8mm pixel pitch display.
C, the analysis of the virtual pixel display high-definition display, also known as high-definition display.
LED display Category:
First, indoor full color
LED TubePH2, PH4, PH5, PH6, PH7.62, PH8, PH10 several models (generally the mainstream market PH6 and PH7.62)
Indoor LED display Price: indoor full color screen is also a three-mile and three and a price differential between two models is probably a lot of difference per square meter.
Indoor full color led display of the chipset, but also the general points made chips (4 types), domestically produced advanced chip (3 classes), senior U.S. chip (Class 2), Japan advanced chips (Class 1). Japan's most senior Asian original for advanced chips (Class 1). The average per square meter to 10 times more than domestic.
Second, full-color outdoor LED
PH10, PH12, PH16, PH20, PH25, PH31.25 several models (generally the mainstream market PH12 and PH16)
Outdoor LED display prices: Outdoor full color
LED Display made the die can be divided into general chip (4 types), domestically produced advanced chip (3 classes), senior U.S. chip (Class 2), Japan advanced chips (Class 1). Japan's most senior Asian original for advanced chips (Class 1). The average per square meter than the domestic one-fold to 1.5-fold.
