For retail, catering and selfservice applications, touch displays serve as the core interactive component of commercial devices. Many overseas buyers only focus on size and upfront price during procurement, while overlooking realworld operating conditions. Once deployed, devices may suffer from washedout screens under strong light, unresponsive performance under extreme temperature shifts, and frequent failures after longhour operation, resulting in high maintenance and replacement costs. Drawing on rich experience in global commercial terminal projects, TaixunPOS sorts out key selection criteria for commercial touch displays to help purchasers and system integrators avoid common pitfalls.
