Problems solved by technology

This will result in a huge waste of cost
[0004] Moreover, at this stage, the production of various display devices, especially display screens, generally requires proofing and mass production after confirmation by customers. The general proofing cycle needs to be relatively long, and the time required from proofing to finished products is also very long.
And the production of a display screen requires different manufacturers to produce due to its different production processes and components. Therefore, the compatibility of various components has also become a major problem in the display effect of the display screen.
