The AC / DC converter 119a functions as a charging unit when the battery 120 is charged with external power. The charge switching unit 119b switches between connection / disconnection of the AC / DC converter 119a and the battery 120 to switch whether to charge the battery 120 or not. The power supply switching unit 119c selects one of the external power and the battery 120 as the power supply for each unit of the video display device 1. Specifically, the power supply switching unit 119c selectively connects either the AC / DC converter 119a or the battery 120 to the power supply switching units 119d and 119e. The power supply switching units 119d and 119e switch connection and disconnection between the power switching unit 119c and each unit to which power is supplied. In the present embodiment, the power supply switching unit 119d switches between power supply and cutoff to the control unit 110 and the like, while the power supply switching unit 119e switches between local power supply and cutoff to the video display unit 106. .
　本実施形態では、充電切換部１１９ｂにおけるバッテリ１２０を充電するか否かの切り換え、電源切換部１１９ｃにおける電源の択一的な切り換え（選択）、および電源供給切換部１１９ｅにおける映像表示部１０６への電源の供給および遮断の切り換えは、制御部１１０が電気的に制御することができる。また、電源供給切換部１１９ｄにおける回路基板（図示せず）や制御部１１０等への電源（主電源）の供給および遮断の切り換えは、電源操作スイッチ（図示せず）等の操作に基づいて機械的に実行される。 In the present embodiment, switching whether or not the battery 120 is charged in the charge switching unit 119b, alternative switching (selection) of the power source in the power source switching unit 119c, and switching to the video display unit 106 in the power supply switching unit 119e. Switching between power supply and cutoff can be electrically controlled by the control unit 110.

Is executed automatically.
　電源供給切換部１１９ｅにおける映像表示部１０６への電源の供給および遮断の切り換えは、リモコン２０１に設けられた操作ボタン（図示せず）の電源のオン操作（供給させる操作）またはオフ操作（遮断させる操作）に対応する信号が受光部１１４で受光された際に、実行される。ユーザ（オペレータ）がリモコン２０１の操作ボタンで映像表示装置１の電源を遮断する操作を行った場合には、映像表示部１０６への電源電力の供給は遮断されるものの、制御部１１０や回路基板の各部等への電源電力の供給は遮断されない。すなわち、リモコン２０１の操作ボタンによる電源のオフ操作によって、映像表示装置１は、映像表示装置１の少なくとも映像表示部１０６を含む一部の電源が局所的に遮断された所謂スタンバイ状態となる。なお、電源供給切換部１１９ｅによって電源が局所的に遮断される部分には、少なくとも映像表示部１０６が含まれていれば良く、他のデバイス（例えばハードディスクドライブ等）が含まれてもよい。 The power supply switching unit 119e switches between power supply to the video display unit 106 and switching off of the power button on the operation button (not shown) provided on the remote controller 201 (operation for supplying) or off operation (blocking). This is executed when a signal corresponding to (operation) is received by the light receiving unit 114. When the user (operator) performs an operation of shutting off the power supply of the video display device 1 with the operation button of the remote controller 201, the supply of power to the video display unit 106 is cut off, but the control unit 110 and the circuit board are cut off. The supply of power to the various parts is not cut off. In other words, the video display device 1 enters a so-called standby state in which at least a part of the power source including the video display unit 106 of the video display device 1 is locally shut off by the power-off operation using the operation button of the remote controller 201. It should be noted that at least the video display unit 106 may be included in the portion where the power supply is locally cut off by the power supply switching unit 119e, and other devices (for example, a hard disk drive or the like) may be included.
　そして、制御部１１０は、インストールされたプログラムを実行することで、図４に例示する機能部（例えば、電力検知部１１０ａや、充電制御部１１０ｂ、電源切換制御部１１０ｃ、局所電源制御部（電源制御部）１１０ｄ、表示制御部１１０ｅ、音声制御部１１０ｆ、計時部１１０ｇ等）として動作する。すなわち、プログラムには、制御部１１０を、電力検知部１１０ａや、充電制御部１１０ｂ、電源切換制御部１１０ｃ、局所電源制御部１１０ｄ、表示制御部１１０ｅ、音声制御部１１０ｆ、計時部１１０ｇ等として動作させるモジュールが含まれている。 Then, the control unit 110 executes the installed program to thereby execute the function units illustrated in FIG. 4 (for example, the power detection unit 110a, the charge control unit 110b, the power source switching control unit 110c, the local power source control unit (power source Control unit) 110d, display control unit 110e, voice control unit 110f, timing unit 110g, etc.). That is, in the program, the control unit 110 operates as the power detection unit 110a, the charge control unit 110b, the power source switching control unit 110c, the local power source control unit 110d, the display control unit 110e, the voice control unit 110f, the time measuring unit 110g, and the like. The module to be included is included.
　上述した構成を備えた本実施形態にかかる映像表示装置１では、映像表示部１０６の動作中（映像を表示している間）は、バッテリ１２０の充電が実行されない。よって、バッテリ１２０の充電中に映像表示部１０６の動作によって筐体３ａ内の温度が上昇するのを抑制することができる。以下、図５～９を参照して、外部電力で映像が表示されている際に、各種の情報の表示や、バッテリ１２０の充電等が実行される場合の映像表示装置１の動作の一例について説明する。 In the video display device 1 according to the present embodiment having the above-described configuration, the battery 120 is not charged while the video display unit 106 is operating (while displaying video). Therefore, it is possible to suppress the temperature in the housing 3a from rising due to the operation of the video display unit 106 while the battery 120 is being charged. Hereinafter, with reference to FIGS. 5 to 9, an example of the operation of the video display apparatus 1 when various types of information are displayed or the battery 120 is charged while the video is displayed with external power is used. explain.
　本実施形態にかかる映像表示装置１では、プラグ（図示せず）がコンセント（図示せず）に差し込まれるなどして、電源回路１１９に外部電力が供給されている状態（図示しないセンサで外部電力の供給が検知されている状態）では、映像表示部１０６の電源としては、外部電力が選択され、バッテリ１２０は選択されない。すなわち、この場合には、映像表示部１０６は外部電力を電源として動作して、映像を表示する（ステップＳ１）。このステップＳ１では、電源切換制御部１１０ｃとして動作する制御部１１０は、電源切換部１１９ｃを制御して、映像表示装置１の各部の電源として、外部電力を選択している。また、映像表示部１０６の表示画面４で映像が表示されている状態であるため、局所電源制御部１１０ｄとして動作する制御部１１０は、電源供給切換部１１９ｅを制御して、映像表示部１０６に電力を供給する。さらに、本実施形態では、上述したように、映像表示部１０６の動作中は、バッテリ１２０への充電は実行されない。よって、充電制御部１１０ｂとして動作する制御部１１０は、充電切換部１１９ｂを制御して、バッテリ１２０への充電を実行しない。 In the video display device 1 according to the present embodiment, a state in which external power is supplied to the power supply circuit 119 by inserting a plug (not shown) into an outlet (not shown) (external power by a sensor not shown). In the state where the supply of power is detected), external power is selected as the power source of the video display unit 106, and the battery 120 is not selected. That is, in this case, the video display unit 106 operates using external power as a power source to display a video (step S1). In step S1, the control unit 110 operating as the power source switching control unit 110c controls the power source switching unit 119c to select external power as the power source of each unit of the video display device 1. In addition, since the video is being displayed on the display screen 4 of the video display unit 106, the control unit 110 operating as the local power control unit 110d controls the power supply switching unit 119e to display the video display unit 106. Supply power. Furthermore, in the present embodiment, as described above, charging of the battery 120 is not performed while the video display unit 106 is operating. Therefore, control unit 110 operating as charge control unit 110b controls charge switching unit 119b and does not charge battery 120.
　そして、本実施形態では、映像表示部１０６が外部電力を電源として動作している際に、バッテリ１２０の電力を監視する。すなわち、電力検知部１１０ａとして動作する制御部１１０は、バッテリ１２０の電力（例えば電圧）を検知するセンサ１１６から信号を受け取って、バッテリ１２０の電力（例えば電圧）の検知結果を得る（ステップＳ２）。 In this embodiment, the power of the battery 120 is monitored when the video display unit 106 is operating with external power as a power source. That is, the control unit 110 operating as the power detection unit 110a receives a signal from the sensor 116 that detects the power (for example, voltage) of the battery 120, and obtains the detection result of the power (for example, voltage) of the battery 120 (step S2). .
　次に、制御部１１０は、検知結果（例えば電圧）を所定の閾値と比較する（ステップＳ３）。ステップＳ３により、バッテリ１２０の電力が所定の閾値と同じかあるいは閾値未満であることが判明した場合、すなわち、図５の例では、バッテリ１２０の電圧が所定値以下であることが判明した場合には（ステップＳ３でＹｅｓ）、表示制御部１１０ｅとして動作する制御部１１０は、表示処理部１０５を制御して、表示画面４で表示される映像信号に、注意情報またはリモコン２０１による電源遮断操作を促す情報を重畳する。なお、バッテリ１２０の電圧が所定値より大きい場合には、ステップＳ２に戻る。 Next, the control unit 110 compares the detection result (for example, voltage) with a predetermined threshold (step S3). When it is determined in step S3 that the power of the battery 120 is equal to or less than the predetermined threshold, that is, in the example of FIG. 5, when it is determined that the voltage of the battery 120 is equal to or lower than the predetermined value. (Yes in step S3), the control unit 110 that operates as the display control unit 110e controls the display processing unit 105 to apply attention information or power-off operation by the remote controller 201 to the video signal displayed on the display screen 4. Superimpose prompting information. If the voltage of battery 120 is greater than the predetermined value, the process returns to step S2.
　図６は、映像Ｉｍ１とともに注意情報Ｉｍ３が表示された表示画面４の一例を示す。この図６の例では、注意情報Ｉｍ３が、表示画面４の周縁部（隅部）に、容量が少なくなった電池を模したデザイン（画像）として表示されている（ステップＳ４）。 FIG. 6 shows an example of the display screen 4 on which the attention information Im3 is displayed together with the video Im1. In the example of FIG. 6, the attention information Im3 is displayed on the peripheral edge (corner) of the display screen 4 as a design (image) imitating a battery with reduced capacity (step S4).
　図７は、映像Ｉｍ１とともに、注意情報Ｉｍ３，Ｉｍ４とリモコン２０１による電源遮断操作を促す情報Ｉｍ５とが表示された表示画面４上の一例を示す。この図７の例では、図６と同様の注意情報Ｉｍ３とともに、注意情報Ｉｍ４が、表示画面４内（本実施形態では下方）の枠内に、「バッテリ残量が不足しています。」という文字として表示されている。さらに、その枠内には、リモコン２０１による電源遮断操作を促す情報Ｉｍ５が、「リモコンの電源ボタンで電源を切り、バッテリを充電することをおすすめします。」という文字として表示されている（ステップＳ４）。また、図６，７の画像Ｉｍ２は、選局されたチャネル名や、番組名、時刻等を示す画像や文字である。 FIG. 7 shows an example on the display screen 4 on which the attention information Im3, Im4 and the information Im5 prompting the power-off operation by the remote controller 201 are displayed together with the video Im1. In the example of FIG. 7, the attention information Im4 as well as the attention information Im3 similar to FIG. 6 is displayed in the frame of the display screen 4 (downward in the present embodiment) “the battery is insufficient”. It is displayed as a character. Further, in the frame, information Im5 for prompting the power-off operation by the remote controller 201 is displayed as the characters “It is recommended to turn off the power with the power button on the remote controller and charge the battery” (step S4). 6 and 7 are images and characters indicating the selected channel name, program name, time, and the like.
