Description

technical field

[0001] The invention relates to an automatic power test system and method for display equipment on a production line. Background technique

[0002] In the production of display equipment such as LCD monitors and LCD TVs, it is necessary to test whether the energy consumption of the display equipment in normal operation and energy-saving mode is qualified according to Energy Star or other standards. It is specifically divided into two parts: one is the power of the whole machine in normal operation The power required for the display to display a full white screen under the specified settings (brightness and contrast are factory settings); the second is the power in energy-saving mode. The power required for the display to automatically enter the energy-saving mode when there is no signal input . The overall power of the normal work and the power of the energy-saving mode are an important parameter to measure whether the display is energy-saving and environmen...
