Problems solved by technology

[0003] As the current display panel industry is developing towards automatic technology, but the product process design and testing equipment have not yet fully matched, there are still many problems to be improved in the known testing devices and methods for display panels.
[0004] Generally speaking, the design of commercially available display panel aging testing machines is to install the display panel to be tested on a fixed rack (Rack) in the furnace before testing. Since the working surface of the rack is designed to be two sides, each side At least one person must be arranged to do loading/unloading (Load/Unload) and inspection work
In addition, when the operator is engaged in disassembly operations or maintenance and repair work, the utilization rate of the test machine is zero, and the machine operator needs to wait aside, resulting in the lengthening of the entire cycle test schedule (Cycle time) , and it consumes labor costs, so the production capacity is limited
[0005] In addition, due to the small operating surface of the testing machine, when the engineers perform maintenance and testing of the circuit in the furnace, the operating space is narrow, which seriously affects the working efficiency
In addition, the drive circuit is installed on a fixed shelf outside the furnace, and then connected to the conversion board in the furnace by wires. The number of cables is large and t

Description

technical field [0001] The invention relates to a device, and in particular to a high-temperature aging test device for a display panel (Display Panel). Background technique [0002] Since the invention of the first black-and-white television with a cathode ray tube (Cathode Ray Tube, CRT) working mode, display technology has been evolving at a rapid pace. At present, the display technology has been mature and popular, such as mobile phones, language translators, digital cameras, digital video cameras, TVs, personal digital assistants (PDA, personal digital assistant), notebook computers and even desktop displays have their scope of application . [0003] As the current display panel industry is developing towards automatic technology, but the product process design and testing equipment are not fully matched, there are still many problems to be improved in the known display panel testing devices and methods. [0004] Generally speaking, the design of commercially availabl...
