New description: [New technology field] [0001] This work is about a display, especially regarding a display with power saving function. [Prior Art] [0002] In recent years, as environmental awareness has become more and more important, the demand for energy conservation has also received increasing attention. All power-related mechanical equipment, home appliances, and computer products are designed in the direction of how to use the minimum power for maximum performance. [0003] Taking the demonstration of jnifw copy or the current computer on the market as an example, the power supply of the display has a power-saving design. The use of the # in the computer operating system used by the user is done in the system. Set, 7 cases of power-saving operation mode settings provided in the computer operating system, if the computer is not used. How long will the display automatically enter the power-saving operation mode or turn off the entire display. However, 4 operations i# spicy: code. First, the user must deliberately set this mode of operation. If 'Yes after|Yes: Pre-determine the parameters of this mode, -., "-rs ' number, will not be able to achieve the energy-saving effect table, *cn [0004] In addition, VESA (Video Electronics Standard Association)-compliant display If the connected computer does not have any operation for a long time, the timing controller (Timing Controller, TC0N) and the backlight of the display will be turned off. However, the operation method of this VESA standard only makes the entire display completely stop operating, which is very inconvenient for the user. Because of this architecture, the display can only be used or closed, there is no other form number A0101 page 3 / 12 pages M409654 selection, therefore, in order to avoid the user to stop the operation for a short time to close the display, usually This computer timing does not have any operational action to control the time to turn off the display is set very long, which will not be as good as expected for the entire power saving effect. [0005] Therefore, if a new technology can be provided, the disadvantages of the conventional technology that the user needs to set the shutdown time themselves can be solved, which can help the display to save energy more effectively. [New content] [0006] In view of this, the purpose of this creation is to propose a display with power saving function, which can adjust the light emitted by the backlight and reduce the power consumption of the backlight. .
