A patent showing a refined fully articulating screen for cameras has appeared at the Japan patent office (Patent application: 2018-133632).
This patent actually looks at changing the backlight intensity of the LCD depending on how the articulating screen is positioned.
The second part of this patent application looks at how to make the hinge that operates the articulating screen smaller. The engineering required for these hinges is quite complicated.
From Japan patent application 2018-133632:
Also when the surface where an illuminance detection sensor is arranged when the display device combined with the rotatable biaxial hinge is operated differs from the surface which the display device has turned to largely, an illuminance detection sensor will be interlocked with, and the brilliance control of a display device will be controlled by a prior art. that is, a luminance change of an unsuitable display device (TFT) is made — like — problem occurs. When the illuminance sensor was provided in the rotatable display unit, the problem that enlargement, i.e., a camera, will be enlarged by the display unit existed.
Then, the object of this invention arranges an illuminance sensor to the dead space in a camera body, and miniaturizes a camera body. In addition, it is having the display device combined with the illuminance detection means and the rotatable biaxial hinge, and making suitable intensity control of the aforementioned display device the aforementioned illuminance detection means according to the position state of the above-mentioned rotatable biaxial hinge.
