This is a used product.
We will test this product before shipment to ensure that the buyer can use it normally, including normal display, no lines, no liquid leakage, backlight can be bright, and so on.
The old and new used products are generally controlled at 80% or more, and they look very new. If the product is special, we will send a photo to the buyer to confirm if the request is reached.
Because the use environment of industrial products is quite special, sellers of second-hand products can only provide a 7-day warranty (calculated from the date of receipt of the express delivery). If the quality requirements are relatively high, it is recommended to purchase a brand new product.
Due to changes in the LCD production process and the circuits/ICs of different batches of products, there may be changes, but the sizes, screens, interfaces, and screw holes of the new and old products are basically the same. Unless otherwise specified, just connect the new module exactly as the old product technical standard.
There may be big differences between different batches of products of the same model, causing the equipment to not work normally. Before purchasing, it is recommended that buyers take photos of the front and back of the LCD screen to our engineers for confirmation to avoid product inconsistencies.
