EP-CA22

What the Sharp EP-CA22 is

The Sharp EP-CA22 is a 28.5-inch ePaper display in A2 format, with an active area of 592 x 418 mm and a native resolution of 2160 x 3060. It is designed to show static full-colour content, such as a menu, a timetable or a notice, and to hold that image without drawing power. Electricity is only used when the content changes, so the panel suits information that needs regular updates but stays on screen for long periods.

Specifications that shape the buying decision

Three figures matter most when comparing this model. The 2160 x 3060 native resolution gives a clear portrait image at A2 size. The USB-C power input is rated at 16 W, and an AC power adapter is included in the box. The operating range of 0 to +50 °C and the operating humidity of 20 to 80 percent set the limits for where the panel can be used.

• Content can be loaded from a PC, a USB memory stick, Wi-Fi or Bluetooth 5.0.
• Wi-Fi supports IEEE802.11 ac/n/a/g/b, and the source data lists IEEE802.1X for Wi-Fi security.
• Two USB-C ports handle power, data and USB memory.
• The panel weighs 2.3 kg and measures 617.8 x 438 x 14.7 mm, with a 200 x 200 mm VESA pattern using M4 holes.
• The manufacturer lists recycled plastic among the materials used in the product.

Where it fits in Qatar

In a hotel or serviced apartment in West Bay, the EP-CA22 can display a breakfast menu or allergen information at a restaurant entrance, where a printed sheet would fade or need replacing. In a clinic in Msheireb, it can show a waiting-area timetable or service directory, updated from a staff laptop. At a university building in Education City, it can carry room bookings or directions beside a lift lobby. Its low-reflection surface stays readable in bright daylight, but a site check is advised before placing it in direct sun.

Summer temperatures in Doha can exceed 45 °C, and the upper operating limit is 50 °C, so the margin is limited. Keep the display out of direct sunlight and away from heat sources. The source data does not give an ingress protection rating, so confirm any exposed or window-side location with the SmartRooms Qatar team before installation.

What to plan before installation

Although the panel is light, start by choosing the mounting point. The box includes hanging brackets, screws and cable clamps, and the display can also stand free. Choose a wall that can carry the load, check that the 200 x 200 mm VESA pattern suits your bracket, and plan where the power cable or battery operation will go. Because power is only needed when content changes, not every display location needs a permanent socket, but the included adapter should be used where mains power is available. Confirm the adapter input voltage with the SmartRooms Qatar team before ordering, as the source data does not state it.

SmartRooms Qatar offers a free site survey, professional installation and delivery to all eight municipalities of Qatar. Organisations buying several units for a school, clinic or government office can order by LPO or through a tender. The product is covered by the manufacturer's three-year warranty.
