31、/p><p>　　2 Overview </p><p>　　A4s is a high-end receiving card developed by NovaStar, featuring small size and full functions with a single card loading capacity up to 256×256 (PWM IC) pixels.

32、 </p><p>　　A4s supports pixel level brightness and chroma calibration, which removes color difference effectively and improves display consistency of LED images. In addition, it also supports image rotation

33、in 90° increments, creating richer images and improving visual experiences. </p><p>　　Software and hardware designs of the A4s concern the user deployment as well as operating and maintenance scenarios,

34、 enabling easier deployment, more stable operating and more efficient maintenance. </p><p>　　Advanced hardware design: </p><p>　　Small size and thinner thickness save space for increasingly narr

35、ower cabinet space and smaller spacing between lamps. </p><p>　　Use high-density connector which is resistant to dust and vibration and features high stability and high reliability. </p><p>　　As
