M350028 八、新型說明： 【新型所屬之技術領域】 本新型係關於一種可攜式電子裝置，特別是一種具有 省電功能之可攜式電子裝置。 【先前技術】 目前，可攜式電子裝置如行動電話、筆記型電腦、個 人行動助理（Personal Digital Assistant，PDA)、攝影機或數 位相機等大多皆具備有液晶顯示螢幕，而液晶顯示螢幕須 藉外部光源才可達到顯示效果。一般的液晶顯示螢幕皆採 用背光模組，而背光模組主要提供液晶面板均勻與高亮度 的光源。 近年隨著液晶顯示螢幕製造技術的提昇，液晶顯示螢 幕朝大尺寸的趨勢發展，而背光模組則必須考量輕量化、 薄型化、低耗電、高亮度及降低成本等市場需求以保持市 場競爭力。 然而，由於可攜式電子裝置之電力供應有限，而大尺 寸之液晶螢幕搭配背光模組將更為耗電，因此，將使得可 攜式電子裝置之可使用時間大為縮短，而且必須時常更換 電池或充電。 此外，除了上述使用不便的問題外，更將造成電能的 浪費或廢棄電池的產生。由於，可攜式電子裝置之種類繁 多，所以其液晶螢幕耗電問題所造成的能源浪費將是極待 解決之問題。 • M350028 【新型内容】M350028 VIII. New description: [New technical field] The present invention relates to a portable electronic device, in particular to a portable electronic device with power saving function. [Prior Art] Currently, portable electronic devices such as mobile phones, notebook computers, personal digital assistants (PDAs), video cameras, or digital cameras all have liquid crystal display screens, and liquid crystal display screens must be externally used. The light source can only achieve the display effect. The general LCD screen uses a backlight module, and the backlight module mainly provides a uniform and high-intensity light source for the liquid crystal panel. In recent years, with the improvement of liquid crystal display screen manufacturing technology, the liquid crystal display screen has been moving toward a large size trend, and the backlight module must consider market demands such as light weight, thinness, low power consumption, high brightness and low cost to maintain market competition. force. However, since the power supply of the portable electronic device is limited, and the large-sized LCD screen and the backlight module are more power-consuming, the usable time of the portable electronic device is greatly shortened, and must be replaced from time to time. Battery or charging. In addition, in addition to the above-mentioned problems of inconvenient use, it will result in waste of electric energy or generation of waste batteries. Due to the wide variety of portable electronic devices, the energy waste caused by the power consumption of the LCD screen will be an extremely problem to be solved. • M350028 [new content]

The Power field displays images. Microprocessing The electrical energy is supplied to the liquid crystal panel to store electrical energy and to store the stored electrical energy. The early detection unit 130 detects the power supply unit. When the power of the power measurement unit 13 is lower than the rated value, the micro processing unit, 'to the power supply unit 120 stores the displayed image and displays the image on the portion to reduce the liquid crystal. The panel can extend the usable area of the portable electronic device, thereby saving electricity, and the rating is a preset amount of $. When the rhyme value is set, it means that the power stored in the fault is sufficient. The comparison benchmark is higher than the "power shortage, so it is necessary to start the province two". When the value is set, it means storage example, such as ~ can " electric function. 130 detects that the power supply unit has limited power. When the voltage is detected, the micro-processing unit 11 stores the power of the battery below the amount of the image and displays the liquid crystal panel (10), image/, and parts of the device. ;, the display area, that is, shrinking +; night crystal panel 1 Π η τ, please refer to "2nd 8th 盥" 〇 0, so you can save energy.

In the above, the second area _ corresponds to the display area light source 142 which does not display the liquid crystal % of the image, thereby saving electric energy. Here, the light source 14 2 can selectively use the sound and light diode. M350028 Please refer to "Fig. 3" A block diagram of a portable electronic device having a power saving function according to an embodiment of the present invention. Among them, a switch 150 is further included. The switch 150 is electrically connected to the microprocessor unit 110. The user can manually control the micro processing unit 110 to reduce the image displayed by the liquid crystal panel 100 through the switch 150, and display the image in a part of the display area and turn off the light source 142 corresponding to the display area where the image is not displayed. A storage unit 160 is included. The storage unit 160 is electrically connected to the micro processing unit 110. The storage unit 160 stores the rated value of the preset power potential, and the voltage detecting unit 130 according to the rated value is a comparison benchmark for storing the electric energy. Please refer to "FIG. 4A" and "FIG. 4B" for a schematic diagram of a portable electronic device having a power saving function according to an embodiment of the present invention. As shown in Fig. 4A, when the power stored in the power supply unit 120 can be higher than the rated value, it means that the power is sufficient, so all the display areas of the liquid crystal panel 100 will display the full size image. As shown in "Fig. 4B", - when the power stored in the power supply unit 120 is lower than the rated value, the representative power is insufficient. At this time, only part of the display area will display an image, and the image will be processed via micro processing. The unit 110 is reduced in size and displayed on the liquid crystal panel 100. For further explanation, for example, a portable electronic device such as a digital camera has a liquid crystal panel 100 for displaying a captured image. When the power supply unit 120 (eg, battery) is detected by the internal voltage detecting unit 130, the power stored in the M350028 is lower than the rated value of the power potential preset in the storage unit 16〇. The unit 110 will reduce the image and display the reduced image in a part of the display area of the liquid crystal panel 1 , and further turn off the light source ( 4 ) of the backlight module 14 in the display area where the image is not displayed, so the back
