Abstract

A video display system with a power saving function is provided. The video display system includes a display panel, a power supply device, a control circuit, and a detecting device. When the detecting device detects that an object appears in a predetermined distance from the display panel, the detecting device generates a first detect signal to the control circuit to decrease the power supply from the power supply device to the display panel.

As shown in FIG. 1, the portable electronic device 10 includes a main system circuit 30 for controlling operations of other circuit components of the portable electronic device 10 and an image display system 20 for controlling image display. In order to assist the user to operate the portable electronic device 10. The main system circuit 30 includes at least one input device 32 for users to operate the portable electronic device 10, and the image display system 20 includes a display panel 2 2, a power supply device 24, and The control circuit 26 and the display panel 22 include at least one input port to receive a data signal from the main system circuit 30 and perform image display according to the data signal. The power supply device 24 is used to provide Power supply for image display system 20.

Description of the invention (4) In the panel, these self-emitting display panels will not be able to be partially shut down using the above method, which will cause continuous power consumption. . Therefore, how to improve the power saving mechanism of the image display system so that it can more accurately determine the use status of the image display system is an important direction of current research and development. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an image display system with a power saving function to solve the above problems. A preferred embodiment of the present invention provides an image display system with a power saving function, which includes a display panel with an image display function; a power supply device for supplying power required by the image display system; a control A circuit electrically connected to the display panel and the power supply device for controlling the power supply of the power supply device to the display panel; and a detection device electrically connected to the control circuit.

For example, 3 to 5 ^ = Device 1 2 8 彳 When detecting a predetermined distance in front of the display panel 1 2 2 (such as a knife / knife), a detection object 1 2 8 will generate a phase A < Brother-I detection signal to the control circuit 1 2 6 and when the control electric Gonglang receives the first detection signal, the control circuit 1 2 6 will reduce the system = supply device 1 2 4 pairs of display panels 1 2 2 power supply. In addition, the control circuit 1 2 and 2 6 include a memory to reduce the power supply of the power supply device 1 2 4 to the display panel according to the pre / history mode stored in the memory. Panel 1 2 2 enters a standby state 1245949 ------------ ^ 14 ^ 92106998 _________________ 生 _ 月日改五、 Explanation of invention (7) " ― output with low power at the same time, or Directly enter a shutdown state without displaying any = shadow. Conversely, when the detection device 128 detects that the shielding object is removed within a μ pre-distance from the display panel 122, the detection device i 2 8 will generate a corresponding second detection signal to the control circuit 1 2 6. Restore the power supply of the power supply device 1 2 4 to the display panel 1 2 2. It is further explained here that the power saving operation of the image display system 120 of the present invention is as follows: Under most use conditions, when an object is covered by a memory at a distance from the front of the display panel 122, it usually represents = user It is not necessary to use the display panel 丄 2 2 to provide information, so it is uncertain whether the other circuit components are still in use at this time. You can reduce the power supply to the display panel 122 until the shielding object is removed. Before resuming power supply to reduce unnecessary power waste. For example, when the mobile phone is placed in a bag, the display panel 1 2 2 is shielded, so even if a call comes in or the input device 1 3 2 is touched by mistake, the display panel 1 2 2 will still maintain low power. The output or closed state, even if the user cannot answer the phone for any reason, and the phone keeps coming in, it will not cause excessive power consumption. And when the user takes ‘action, the words are taken out of the bag, the display panel 12 will be restored to the normal display state for the user to operate the mobile phone. Or when the user uses a mobile phone to make a call and puts it in the ear, 'because the detection device 1 2 8 will detect that there is a covering object within a preset distance in front of the display panel 1 2 2', it displays The panel 1 2 2 will output at low power or enter the shutdown state, as long as the user does not remove the mobile phone from his ear, even if the user performs some operations on the mobile phone (such as adjusting the audio

In addition, according to the image display system 120 of the present invention, in addition to the power saving operation by the above method, it can further cooperate with the conventional power saving method, and judge the image display by waiting time or the position of the device such as a slider. The use status of the system 120 is to further save power and avoid unnecessary waste of power. Although the above uses the use of a mobile phone as an example to illustrate the image display system of the present invention, the scope of the present invention is not limited to this, and can be applied to various information products that require image display with the same principle, especially paying attention to the use Various portable electronic devices such as personal digital assistants (PDAs). In addition, in addition to the above design, the image display system according to the present invention can further integrate part of the components in the image display system onto a display panel to form a display panel with a power saving function.

Description of the Invention (10) Compared with the conventional image display system, the image system according to the present invention can be determined by the display panel on it. It is obscured to judge whether the display system is in an unused state. Therefore, the present invention obviously can waste more unnecessary power and achieve the effect of increasing the use time. In addition, the present invention can be applied to some power consumption that cannot be partially shut down. Display panels, such as self-luminous organic electro-luminescent display panels or other electro-luminescent display panels, make it suitable for portable electronic devices that focus on power regulation capabilities, and greatly increase the scope of application of light-emitting display panels. The above description is only a preferred embodiment of the present invention, and any equivalent changes and modifications made in accordance with the scope of this patent should fall within the scope of the present invention. Avoid image display. Saving light on the meaning of each application
