Abstract:
In accordance with one implementation, a method for multiple source light output smoothing includes measuring a light distribution generated by multiple light sources arranged within an electronic device and determining at least one brightness adjustment based on the measured light distribution that is sufficient to locally reduce light output within a discrete region of a surface of the electronic device to satisfy predefined luminosity criteria. The method further includes applying an optical filter between the multiple light sources and the surface, the optical filter configured to reduce light output within the discrete region according to the determined at least one brightness adjustment.
Abstract:
A display panel and a display apparatus including the display panel are provided. The display panel includes: a light transmitter disposed on a first pixel electrode and a light converting unit disposed on a second pixel electrode. A portion of the light converting unit extends toward the light transmitter and covers a part of the first pixel electrode.
Abstract:
A driving circuit for an LED backlight with at least a first and a second segment (Sl, S2) has a first terminal (11), a second terminal (12) for sensing a first signal (Sgl), a third terminal (13) for connecting to a first current generating unit (Tl, CS1) for providing a first driving current (11), a first current regulation circuit (PWM1) for controlling the first current generating unit (CS1, Tl), a fourth terminal (22) for sensing a second signal (Sg2), a fifth terminal (23) for connecting to a second current generating unit (CS2, T2) for providing a second driving current (12), a second current regulation circuit (PWM2) for controlling the second current generating unit (CS2, T2), and a control unit (CTL) which is prepared to adjust the supply voltage (Vled) and to adjust the first and/or second driving current (11, 12) in dependence on the first and the second signal (Sgl, Sg2) by means of the first and/or the second current regulation circuits (PWM1, PWM2).
