The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen. A display may exhibit different behavior in horizontal and vertical axes, requiring users and manufacturers to specify maximum usable viewing angles in both directions.
In filmmaking, the 180-degree rule [1] is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second ...
The articulating screen is known under different other names such as flip-out screen, flip screen, adjustable screen, articulated screen, or hinged screen. According to the way it moves, there are five main types: The display moves around one axis, so that it only tilts. It is called tilting screen or tiltable screen.
One of the keys to maintaining screen direction is the 180-degree rule, which cuts a horizontal line through the frame. [3] Actors are then filmed from only one side of the axis, maintaining the orientation of the space for the viewer. [4] This can be manipulated specifically to create a shift in perspective.
STN displays improved on that by twisting the liquid crystal molecules at a much greater angle, typically between 180 and 270 degrees. This allows for a sharper image and passive matrix addressing , a simpler way to control the pixels in an LCD.
The unique feature of the DOME lens is the actual shape of the glass, the projected image spill out from the top and all around the circumference of the lens. The biggest advantage is how this type of lens maintains focus over the full 180 x 180 field of view.
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
This generates an egg-shaped image with more than 180° view. [16] Popular in the 1970s and 1980s, but now superseded by digital presentation software, Multi-image [17] (also known as multi-image slide presentations, slide shows or diaporamas) 35mm slide projections onto one or more screens characteristically lent themselves to the wide screen ...
