Problems solved by technology

[0007] Due to the narrow viewing angle of the display screen in the existing display device, it is difficult to see the screen display from an oblique direction.
However, this kind of display device cannot see the screen display from an oblique direction at all, and even when viewed from other angles, it is only difficult to see due to low contrast.
Therefore, there is a problem that if the display screen is watched from an oblique direction, a third person can peek at it.

Embodiment Construction

[0062] FIG. 1 is an external view showing an example of a portable information terminal device according to an embodiment of the present invention, and a mobile phone 1 is shown as an example of the portable information terminal device. The mobile phone 1 is a foldable mobile phone. The display frame 100 and the operation frame 200 are connected by a hinge part 300 , so that one side of the display frame 100 and the operation frame 200 can be folded in half.

[0063] In the display frame 100 , the main display unit 101 and earphones 103 are disposed on the inner side when folded, and the sub-display 102 and camera 104 are placed on the outer side when folded. In addition, the operation frame 200 has a plurality of operation keys 201 and a call microphone 203 arranged on the frame body surface that becomes the inner side when it is folded. Such a foldable mobile phone 1 can be carried in a folded case, and when the case is unfolded, the operation key 201 can be pressed while vi...

Abstract

Provided are a mobile information terminal device and a display terminal device, which can suppress an oblique peep of a display screen effectively. A display device (5) has a display area formed into a first pattern area and a second pattern area. In the mode of a wide field of view, the display device (5) gives the entire display area a large angle of visibility. In the mode of a narrow view field, the display device (5) dynamically interchanges a first division state, in which the area other than the first pattern area is given a small angle of visibility, and a second division state, in which the area other than the second pattern area is given a small angle of visibility. In case the display area of the narrow view field is obliquely peeped, therefore, a motion pattern of a high contrast due to the difference in the angle of visibility can be seen to attract the consciousness of the peeper. As a result, the screen display cannot be easily discriminated, even if it is seen in a low contrast.

Description

technical field [0001] The present invention relates to a portable information terminal device and a display terminal device, and more specifically, relates to a display terminal device capable of variably controlling the viewing angle of a display device displaying various information and capable of controlling peeping of its display screen, and a display terminal device having such a display device. portable information terminal devices such as mobile phones. Background technique [0002] Small portable information terminal devices can be carried in pockets or handbags, and can be used in various places. For example, it is often used in meeting rooms, restaurants, stations, trains, and buses. In this case, there is a problem that the display screen of the portable information terminal device may be peeped by a third party nearby, and the user's personal privacy cannot be ensured. [0003] As a countermeasure against such peeping, it is considered to narrow the viewing an...
