MODEL LV-43 · OPEN FRAME OVERLAY KIT · 20 POINTS · USB 2.0 FULL-SPEED
The kit builders ask for by name
The LV-43 is the catalogue's clearest statement of what an infrared overlay kit is: a 43-inch aluminium alloy frame, 20 touch points, 32768 × 32768 sensing resolution, and a USB 2.0 full-speed interface, sold explicitly as an open-frame overlay kit. It appears twice in the manufacturer's catalogue — once specified for kiosk and machine integration, once in a DIY configuration for schools — which reflects its real market: 43 inches is the largest size a single integrator can handle alone on a bench, and the size at which counter terminals, teaching podiums and mid-format signage converge. If you are building one prototype to prove a product, this is usually the frame the proof should be built on.

Two catalogue configurations, one frame
The kiosk configuration is the integration build: open-frame mounting, intended to disappear into a housing with the display. The school DIY configuration is the same sensing programme presented for education retrofits — teaching, meeting and training use is stated on that listing — where the frame mounts onto an existing classroom display. The difference that matters at ordering is not the sensor (identical resolution and points) but the paperwork: integrators should order against the kiosk listing so the quotation carries the integration specification, schools against the DIY listing. Either way, the frame drawing is confirmed against your display's outer dimensions before production; 43-inch sets differ enough between brands that "43 inch" alone is not a build instruction. Our installation guide shows the assembly and calibration sequence the kit is designed around.
Where 43 inches fits
Counter-height self-service (ticketing, ordering, check-in), podium and lectern displays, mid-size digital signage that invites one user at a time, and classroom satellite displays. For gaming tables and multi-user surfaces, the same programme scales up through the multi touch family; for component-level builds at this size, the 43-inch PCBA module (YCL-43, 5 ms) is in components.
A note on evidence
Every figure on this page traces to the manufacturer's own catalogue listings for this model class — dimensions, touch points, interface and stated standards are quoted from those listings, and anything the listings leave open (certification documents for a specific build, confirmed lead time for a specific quantity) is confirmed at quotation rather than filled in here. That discipline is deliberate: a specification page that invents nothing is the only kind worth engineering against, and it is why the inquiry asks for your display model — so the reply can be written against your unit, with the drawing, instead of against a generic diagonal.
Can the LV-43 be built into a sealed housing?
Yes, as an open-frame kit it is designed for housing integration. Keep the sensing windows unobstructed and ventilate the electronics cavity; declare sealing requirements in the inquiry.
What does the frame need from the host PC?
A USB port and a standard HID touch stack. No vendor driver is required for basic operation on current Windows, Android or Linux systems.
