隨著科技的進步，各種個人裝置的使用越來越普遍，各種小型且由電池供電的顯示器：例如，數位像框(DPF)、手機、掌上電腦(PDA)、移動上網設備(MID)等均會受到電池容量的限制，其顯示時間或通話時間越來越受到考驗。尤其是在戶外場所，難以找到插座進行充電，維持電池的正常供電。With the advancement of technology, the use of various personal devices is becoming more and more common, and various small and battery-powered displays: for example, digital picture frames (DPF), mobile phones, PDAs, mobile Internet devices (MIDs), etc. Due to the limitation of battery capacity, its display time or talk time is increasingly being tested. Especially in outdoor places, it is difficult to find a socket for charging and maintain the normal power supply of the battery.
為此，人們嘗試著利用太陽能模組來對電池進行充電。太陽能模組可以接收太陽光或人工光源的照射，通過光能轉換到電能進而對顯示器的電池充電，這種技術可以籍由光能來延長顯示器的工作或待機時間，對使用者提供了極大的方便。To this end, people have tried to use solar modules to charge the battery.

This technology can extend the working or standby time of the display by light energy, and provides great for the user. Convenience.
先前技術使用到太陽能模組的顯示器大多作為顯示器的輔助充電系統，太陽能模組通常設置在顯示器的表面(如太陽能計算機)或是透過一個介面連接顯示器本體，如第1圖為例，顯示器10具有面板11、背光模組12、太陽能模組13、電池14、主電路15、維持電路16、充電單元17以及開關18；當使用開關18開啟顯示器10時，電池14對主電路15與維持電路16供電時，主電路15係可包含影像處理晶片、記憶單元、供電單元及輸出單元(未圖示)，主電路15的主要功能係供電給面板11與背光模組12，並經由輸出單元供應影像信號給面板做顯示；維持電路16通常具有一個儲能元件與特定功能電路(未圖示)，特定功能電路係用來執行部分待機時需要維持的功能。例如：維持即時時間(Real Time Clock)、時間顯示與維持遙控線路待機之用；當移除電池14供電時，面板11與背光模組12同時停止運作，此時維持電路16仍會由儲能元件供應電能維持特定功能電路的運作；當電池14安裝於顯示器10之內時，電池14會對儲能元件充電，消耗電池內的電能。The display used in the prior art mostly uses a solar module as an auxiliary charging system for the display.

另外太陽能模組13與市電可耦接到充電單元17，詳細運作內容可參考美國專利US6,384,570的內容所述，太陽能模組13作為對電池14充電的輔助，雖可以對於電池電量做輔助補充，但若是電池未裝在顯示器的狀態下或開關完全切斷電池的供電的狀態下，維持電路16僅能由儲能元件供應電能維持特定功能電路的運作，儲能元件通常為金電容(扭扣型或捲繞型電容器)儲存的電容量有限，當耗盡電能時，會將應維持的功能中斷，造成使用者不便。In addition, the solar module 13 and the mains can be coupled to the charging unit 17.

The backlight module 120 and the solar module 130 are disposed inside the display 100 and the backlight module 120 is disposed between the panel 110 and the solar module 130. In this way, the solar module 130 can be hidden inside the display 100, which is more compact than the prior art. The panel 110, the backlight module 120 and the circuit board are usually made of iron (not shown). The assembly module is fixed in the display 100. In order to make the display 100 lighter, a hole is formed in the iron member, and the solar module 130 is disposed corresponding to the opening when combined. At this time, the display 11 The external light can be received by the solar module 130 via the opening of the panel 110 and the backlight module 120.
上述背光模組120的光源可採用冷陰極螢光管、熱陰極螢光管、發光二極體LED或是電激發光片EL等，背光模組120的結構可以是側光式結構、直下型結構或是中空型結構；在本發明中，顯示器100的外部光線(如太陽光或室內光線)係穿過面板110後被太陽能模組130接收，而當背光模組120啟動時產生內部光線照射面板110用以顯示影像，另一方面可照射到太陽能模組130，太陽能模組130即根據上述外部光線或內部光線產生具一電壓值的太陽能電壓。The light source of the backlight module 120 may be a cold cathode fluorescent tube, a hot cathode fluorescent tube, a light emitting diode LED or an electroluminescent sheet EL. The backlight module 120 may be of a side light type structure or a direct type. The structure or the hollow structure; in the present invention, the external light of the display 100 (such as sunlight or indoor light) is received by the solar module 130 after passing through the panel 110, and the internal light is generated when the backlight module 120 is activated. The panel 110 is used to display images, and on the other hand, the solar module 130 is irradiated.

When the battery 140 is not powered or is not mounted on the display, the solar energy The module 130 is separately powered to the sustain circuit 160, and the solar module 130 can be separately powered to the sustain circuit 160 to simplify the circuit design, depending on the designer's choice.

As shown in FIG. 3, the charging controller 154 includes a converting unit 1542, a comparing unit 1544 and an output unit 1546. The converting unit 1542 is configured to convert the voltage value of the solar voltage. Converting to a digital value, the comparing unit 1542 has a first preset value and a second preset value stored in the storage function, and the comparing unit 1542 compares the digit value with the first preset value and the second preset value; 1546 receives the solar voltage, and the output unit 1546 has a function of voltage regulation and outputting a fixed voltage. On an actual circuit, the output unit 1546 can implement the function by using an amplifier. When the comparison unit 1542 compares the digit value to be greater than the first preset value, the comparison unit 1542 causes output unit 1546 to output a first charging voltage to sustain circuit 160, that is, when solar voltage is insufficient, charging controller 154 does not provide power to sustain circuit 160, and when solar voltage is sufficient, charging controller 154 provides a fixed first The charging voltage is applied to the sustain circuit 160; generally, charging the battery 140 requires a higher charging voltage, so when the digital value is greater than When the second preset value is used, the comparing unit 1542 causes the output unit 1546 to output a second charging voltage to the battery 140, the second preset value is greater than the first preset value, and the second charging voltage is greater than the first charging voltage, and the output unit is further A boost circuit (not shown) may be additionally provided to raise the solar voltage to a second charging voltage; when the battery 140 is depleted or not installed on the display and the voltage generated by the solar module 130 is less than the first predetermined value The sustain circuit 160 can only supply power to a particular functional circuit (eg, RTC circuit 152) by an internal tank circuit (eg, gold capacitor 156).
