Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a display device with improved illumination of the display section when a portable device section having a display function is detachably held in a fixed device section.

[Conventional technology]

As this type of device, the one shown in FIG. 3 is known. Here, a portable device part 1 equipped with a display part 3 made of a transparent electrode such as a liquid crystal is detachably attached to a fixing device part 2 that serves as a fixing base for holding the portable device part 1. The portable device section 1 is a watch, a remote control commander, etc., and is usually carried and used, but at night, it is set in the fixed device section 2. Therefore,
In order to make the display section 3 of the portable device section 1 easier to see at night, the fixed device section 2 is provided with an illumination light 4 above and in front of the display section 3. However, in this method, the light from the illumination lamp is projected onto areas other than the display section 3, so there is no effect of making only the display section 3 stand out, and the design is unattractive.

[Problem that the invention attempts to solve]

The present invention was developed based on the above circumstances, and in addition to making the portable device part portable, the lighting configuration is devised so that when it is attached to the fixed device part, the display part exhibits an edge-light effect. This is intended to make the lighting effect of the display part stand out from a design standpoint.

[Means to solve the problem]

For this purpose, the present invention provides that a portable device section having a display section is detachably held on a fixing device section, and that when the portable device section is attached to the fixing device section, the In a display device in which the display section is illuminated by a light emitting source provided on the device section side, the display section is provided with a plurality of pairs of transparent electrodes, and various information is displayed by voltage patterns applied to these electrode pairs. At the same time, a back plate is provided on the back side of the display section and has a light entrance section that takes in light from the light emitting source, and when the portable device section is attached to the fixed device section, the light emitting section is It is characterized in that the light from the source is guided by the back plate through the light incident part and then is led out from behind the display part.

【Example】

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3. In the figure, reference numeral 11 is a portable device section used as a remote control commander, and a display section 13 is provided near the upper center. The display unit 13 is a liquid crystal display device that includes a plurality of pairs of transparent electrodes and displays numbers, characters, figures, etc. by applying a voltage pattern to the pairs of electrodes, and has a transparent back plate 16.
is exposed through the upper window 15 of the portable device section 11. On the other hand, the fixing device section 12 which has a housing section 17 for receiving the portable device section 11 on the front side is an embodiment in which the portable device section 11 is accommodated therein, and the position facing the upper window 15 which is the rear part of the fixing device section 12 is an embodiment in which the portable device section 11 is accommodated here. , the light source 14
Equipped with In such a configuration, at night, the portable device section 1
1, when the fixing device section 12 is held and the light source 14 is working, the light is projected only onto the back plate 16 through the upper window 15, so the display section 13 is illuminated by the edge light effect. As a result, an excellent lighting effect in terms of design can be obtained in which the display section 13 appears to be floating at night. In addition, in the above embodiment, a portable device was explained as a remote control commander.
Applications to watches, electronic desktop calculators, etc. are also widely considered. In addition, although this time we used a liquid crystal display, any light-receiving type display with transparent electrodes could of course be widely used in ECDs and other devices.

[Effect of the idea]

The present invention has been described in detail above, and has the practical effect of achieving effective illumination by light incident from the back plate by taking advantage of the fact that the display section uses transparent electrodes. Since the portable device section is detachably held by the fixing device section, the fixing device section can be remotely controlled when the portable device section is used as a remote control commander, for example. In addition, if the portable device part is, for example, a clock, it can be used as a portable clock that can be used as an illuminated clock when not carried, and if it is an electronic desk calculator, for example, it can be illuminated as needed. It is also possible to use it alone, such as by using it as a calculator.
