Patent ID: 8773326

Claim:
A terminal device including two housings respectively having a display section which are foldably connected via a hinge section, comprising: an opening angle judgment means for detecting an opening angle of the two housings, and judging whether or not the opening angle is smaller than a first predetermined angle; a display control means for controlling luminance of at least one display section of the two housings based on the opening angle, when the opening angle judgment means judges that the opening angle is smaller than the first predetermined angle; and an angle difference judgment means for, when the two housings are in a state of being opened, judging whether or not an angle difference between a first angle and a second angle is greater than a second predetermined angle, where the first angle is a smaller angle of two angles formed by a short side of one of the two housings and a horizontal plane, and the second angle is a smaller angle of two angles formed by a short side of the other of the two housings and the horizontal plane, wherein the display control means reduces luminance of a display section included in a housing with a larger angle of the first angle and the second angle, when the opening angle judgment means judges that the opening angle is smaller than the first predetermined angle and the angle difference between the first angle and the second angle is greater than the second predetermined angle.
