i5A Receiving Card

i5A Receiving Card


i5A adopts a new generation of image processing core, which greatly improves the display effect. Support higher level of color input and gray level output, which creates more delicate images; Great improvement has been done onto low gray scale aspect, which enhances its display effect; higher refresh rate and more stable display images are supported based on high-quality display effect.

i5A Receiving Card

In addition to inherit all the advantages and features 5A had, i5A adopts a new generation of system architecture, and possesses more intelligent function and more stable system. i5A receiving card supports a range of more intelligent and high-end functions like program arbitrary switching, external connect to LCD display module, etc., which lead LED control system to a brand new level.


         More perfect display effect by adopting new processing core.

         High refresh rate, high gray scale and high brightness with conventional chips.

         Perfect performance under lower grayscale status.

         Better detail processing: Partial dark at row, reddish at low gray, shadow problems can be solved.

         Support the effective display at first grayscale value.

         Support 14 bits high-precision point-by-point calibration in the brightness and the chromaticity.

         Support conventional chips, PWM chips and lighting chips, etc.

         Support any scan mode from static to 1/32 scan.

         Support any pumping point and data arbitrary offset and realize various freeform display, spherical display, diamond display, creative display, etc.

         Support signal output for 16 groups of RGBR’ and 20 groups of RGB, 32 groups as extended.

         Large load capacity.

         Wide working voltage range with DC 3.3 -6V.

         Support dual receiving card backup, loop backup, and dual-machine backup, etc.

        Compatible with C series Sender, Z series Sender, S series Sender, etc.
