Abstract

PURPOSE:To contrive the reduction of power consumption in the utilization of an inner battery at the time of the carrying of an electronic appliance by having two modes due to the different power supplying means to the electronic appliance when the inner battery of the electronic appliance is used. CONSTITUTION:It is necessary that driving time in the inner battery is prolonged when the inner battery of the electronic appliance such as a personal computer and a word processor is driven, and this back light mode can be switched to OFF and ON (weak). The light emission level of the ON (weak) is set to the usable minimum brightness and the brightness is fixed. On the other hand, in the back light mode at the time of the driving of AC 100V, only the ON (strong) is used. As the environment for using this mode, an AC receptacle is provided nearby, and the back light is strongly and brightly emitted, so that a demonstration effect at the shopwindow at the time of sale can be enhanced, for instance. Thus, the back light is emitted both when the driving of the inner battery and the AV 100V are drived and the driving time when the inner battery is drived is prolonged.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional technology, when the backlight is emitted when the internal battery of electronic equipment such as a personal computer or word processor is driven, and when it is driven at AC100V, the backlight is emitted in the same mode. Sometimes, even when the above-mentioned electronic device is used in an environment where a backlight is not required, the backlight will emit light, resulting in a problem that the battery life will be significantly impaired and the operating time of the internal battery will be shortened6. Using the backlight to emit light only during operation has the problem that even if the environment in which the electronic device is used requires a backlight, it cannot be used when the electronic device is driven by an internal battery.

[Embodiment] Fig. 1 is a flowchart of the light emission mode of the backlight system of the present invention in an embodiment of the present invention, and shows that when an electronic device such as a personal computer or a word processor is powered by an internal battery, it can be used outside the home. Therefore, it is necessary to extend the operating time of the internal battery. The backlight mode when powered by the internal battery is OF
It is possible to switch between F and ON (weak). The light emission level of ON (weak) is set to the minimum brightness that can be conveniently used, and the brightness is fixed. This minimum brightness and fixed brightness (the user cannot adjust the brightness) prevents wasted power consumption due to unnecessary brightness settings on the user's side, and allows the internal battery to run longer. This increases the portability of small electronic devices such as notebook personal computers and word processors.

The backlight mode when driven at AC100V is O.
Only N (strong). The usage environment for this mode is AC1
If you are in an office or home where a 00V outlet is nearby, you do not have to worry about the operating time as you would when running on an internal battery. This allows electronic devices to be used in environments with varying levels of brightness. In addition, this mode makes the backlight shine strongly and brightly, making it easier to use when selling electronic devices such as personal computers and word processors. It is possible to enhance the effectiveness of in-store demonstrations.

FIG. 2 is an external view of an electronic device with an internal battery level indicator according to another embodiment of the present invention. A part of the main body of an electronic device such as a personal computer or a word processor (1) is provided with an internal battery level indicator (2). This is a glli among electronic devices! When the internal battery is running, the backlight mode is 0FF--ON (when the internal battery is running).
This is so that the user knows when to switch to low). In other words, when using the backlight with the backlight turned on (low), if the remaining battery power becomes low, turn the backlight back on.
By switching to FF and reducing power consumption, the aim is to extend the drive time on the internal battery.
