JPH11211204A - Remote controller with liquid crystal display for air conditioner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a remote controller with a liquid crystal display for an air conditioner in which the visibility of a liquid crystal display section(LCD) can be secured even at night without using electric energy by providing a luminous material sheet on the rear surface of the LCD. SOLUTION: The visibility of the LCD 7 of a remote controller with liquid crystal display for air conditioner is improved by using part of the external light made incident to the LCD 7 as reflected light in day time by tightly sticking a luminous material sheet (luminous film) 8 to the rear surface of the LCD 7 in one body and providing a half-mirror sheet (film) 9 between the sheet 8 and LCD 7. At a dark place at night, on the other hand, the liquid crystal display made on the LCD 7 is made to be clearly visible without using any electric energy by using the light emitted from the light energy stored in a luminous material sheet (luminous film) 8 which stores the daytime light and the light of electric lamps through the half-mirror sheet (film) 9 as the back-light of the LCD 7.

[0001]

The present invention relates to a remote controller with a liquid crystal display for an air conditioner.

[0002]

2. Description of the Related Art It is very common to remotely control various electric appliances by a remote controller with a liquid crystal display. 2. Description of the Related Art In recent years, as the functions of electric devices have become highly functional and diverse, the content of operation with a remote controller has also become diverse. Therefore, the liquid crystal display function is becoming more and more important for setting the operation contents and confirming the setting contents. In particular, with the frequent use of air conditioner remote controls and the diversification of their functions, liquid crystal display functions have become important.

At present, a backlight of a transmission type liquid crystal used for a remote controller generally has an L (light-emitting liquid) using electric energy.
Light from ED or low cathode discharge tube is used. Also, because it is driven by battery power, there is no backlight due to battery life, or the battery switch is used by turning on the lighting switch etc. only when necessary, and it was difficult to understand even the location of the remote control itself in darkness etc. .

[0004]

Accordingly, the present invention uses a light-storing material having a very long light-emitting time without using electric energy in a remote controller having a liquid crystal display function, such as a remote controller for an air conditioner. An object of the present invention is to provide a remote controller with a liquid crystal display of an air conditioner, in which a thin sheet material is provided on the back surface of a transmission type liquid crystal (LCD) and visibility of the liquid crystal display can be ensured even in a dark place at night.

[0005]

According to a first aspect of the present invention, there is provided a remote controller with a liquid crystal display for an air conditioner according to the present invention. Is provided to provide a liquid crystal display device that enhances the visibility of the liquid crystal display at night.

In this way, a thin sheet material using a bright light-storing material having a very long light emission time without using electric energy is provided on the back surface of the transmission type liquid crystal unit (LCD), and air which is frequently used in darkness or the like is provided. Make the liquid crystal display on the remote control display of the harmony machine easier to see.

According to a second aspect of the present invention, there is provided a remote controller with a liquid crystal display for an air conditioner, wherein a half mirror film is provided between a transmission type liquid crystal display portion and a light storage film, and outside light is supplied by the half mirror film during daytime. A liquid crystal that partially enhances the visibility of the liquid crystal display and stores part of the external light in the light storage film, and transmits the light emitted from the light storage film through the half mirror film at night to increase the visibility of the liquid crystal display unit. A configuration including a display device is adopted.

Thus, in order to ensure the visibility of the liquid crystal display of the remote controller display of the air conditioner during the daytime, a half mirror film is provided between the sheet of the phosphorescent material and the liquid crystal display. A part of the light entering from is used as reflected light to improve the visibility of the liquid crystal display. On the other hand, in dark places at night, light emitted from the light storage film that stores light from the day and light from the bulb is used as a backlight for the liquid crystal display with light that has passed through the half mirror, making the remote control operable and convenient. Can be increased.

FIG. 1 is an example of a front display unit of a remote controller of an air conditioner. 1 is an operation switching key (button) for switching between cooling, heating and dry operation modes, 2 is a key for temperature setting, 3 is one of the additional function operations, a good night operation key, and 4 is also an additional function operation. One is a foot control key, 5 is a liquid crystal display screen, and 6 is a body sensor.

First, the operation of the air conditioner is started, and any one of the cooling, heating and dry operation modes is selected by the operation switching key 1 and the desired temperature in the normal operation is set by the temperature setting key 2. Is done. At this time, the temperature setting mode is switched so as to correspond to the normal operation. Then, the set temperature is displayed on the liquid crystal display screen 5, and the normal operation is continued.

Next, by operating the sleep operation key 3 which is one of the additional function operations, the temperature at the time of sleep can be set to an arbitrary rare temperature suitable for the user's preference. Further, the temperature set in the additional function operation can be displayed on the liquid crystal display screen 5 and can be confirmed.

When the foot control operation key 4, which is one of the additional function operations, is selected, the temperature setting mode is switched to the additional function operation mode as in the case of selecting the sleep operation, and the normal operation is performed until now. The temperature setting function corresponding to the mode is operated in the additional function operation mode.
The set temperature in the additional function operation is displayed on the liquid crystal display screen 5 and can be confirmed.

As described above, on the liquid crystal display screen 5 for displaying and confirming the operation contents of the remote controller, various operations such as changing the temperature setting and stopping the operation even in dark places at night are performed.
