Through the development of small-pitch LED displays in the past five years, there has been a huge improvement in the clarity of the display panel. As the density increases, it becomes increasingly difficult to further reduce pixel spacing.
Small pitch LED display
At the same time, the background support system of the LED display is undergoing a deep change. The signal drive system of the display, also known as the sending card, receives the card. The sending card evolved from the original embedded PCI slot to an external type with a separate power module.
After a small pitch application, the standard 1U rack type is adopted. These are only changes in appearance and access mode, in terms of the load capacity of the system, the sending card is also gradually adapting to the video resolution of the standard video format with load, the most typical such as support for 1080P signal single access; The introduction of HDMI interface inputs, etc., is in the front-end matrix of the small-pitch signal access platform, and the spelling control is matched on the interface and resolution.
In terms of receiving cards, the ability of a single card with load increases with the pixel density of the display unit, and the space in the unit is small, and the memory strip receiving card with load strength and small size is gradually derived.
And in terms of double backup of the signal, the small-pitch LED display screen adopts more traditional signal loop forms, in the case of stable and reliable system, this form can achieve a certain degree of double backup, but in the near future, more manufacturers will use the form of dual system cards to replace the signal loop, so that the stability of the system has been greatly improved.
It is foreseeable that the system's receiving card suppliers are seeking breakthroughs in business, and there are also integrated circuit chip forms to explore and discuss, I believe it will not be too long, and there will be subversive forms in the display drive system. At the level of the signal access platform of the video video video wall, equipment suppliers at all levels are also gradually rejecting to accepting small-pitch LEDs.
From the current hardware equipment splicing controller standard splicing wall, the product is output by the initial interface fixed resolution, in order to adapt to the signal access characteristics of small-pitch LED products, the interface resolution can be freely defined.
From the original LED small pitch manufacturers in the whole industry looking for splicers that can customize the output resolution, to the current industry-wide splicers have supported or are trying to support LED splicing, which can not be said to be a technical compromise and progress on the market.
It is not difficult for us to find that LED small-pitch products are gradually infiltrated into the professional display field by traditional commercial display carriers, from the product itself to the background system, adjusting and improving all the time.
