We are currently exploring options for a display in the size range of 4 to 5 inches, preferably driven by either UART or SPI protocols. We are interested in sourcing 1000 pieces for an upcoming project, and our main goal is to find a model that offers the best cost-effectiveness without compromising on quality. Could you provide us with your most economical options that meet these specifications? Additionally, it would be helpful if you could include information about the key features and any available customization options. Looking forward to your prompt response, as we aim to finalize our supplier soon.
