Analysis of three large pixel technologies for LED full color display

LED full-color displays have been widely used in various fields, such as shopping malls, airport train stations, etc. Market penetration is also increasing year by year. Pixel is one of the important technical indicators of full-color LED display . It is necessary to understand the LED display pixel technology. Let's take a look at it below.

1. Dynamic pixel technology: split a pixel into several independent LED units. Each of the LED units reproduces corresponding primary color information of a plurality of adjacent pixels in a time division multiplex manner.

2. Virtual pixel technology: In the display system, when the displayed information is scrolled in a certain direction in a certain direction, a series of movements between two adjacent pixels are generated by utilizing the characteristics of the human short-lived visual effect. Virtual pixels that do not physically exist, thereby adjusting each LED single tube to enhance the resolution of the LED full color display to achieve the best image effect, the theory is to improve the image resolution, generally 4 times.

3. Pixel sharing technology: A complete independent pixel of the display terminal is time-division multiplexed, and is cyclically refreshed by information of multiple adjacent pixels in the signal source. It is understood that a plurality of pixels in the signal source share a complete independent pixel of the display terminal in a time division multiplexing manner.

CAT6A STP Keystone Jack

According to ISO 11801 C 2 Edition standards, T568A 568B wiring standars color code schema, communication speed reaches 10G+. it's your best choice to your high quality cabling solution.

Category 6A is one of the latest standards for networking performance approved by the TIA for twisted pair cables. We offer CAT6A Keystone Jack tested for transmission speeds of up to 500 MHz., making them suitable for 10G networks. At higher data speeds, the signal becomes increasingly vulnerable to electromagnetic interference (EMI). To combat this increased vulnerability, many of our CAT6A patch cables feature increased shielding and crosstalk prevention.

The performance of your 10G data network is only as strong as its strongest link. Reinforce your network with our CAT6A kesytone jack. CAT6A exhibits superior crosstalk prevention to handle noise at higher frequencies than CAT6 can handle. Our CAT6A booted Patch Cables have been speed tested to up to 600 MHz.
