  2. Frontlight - Wikipedia

    The solution; the frontlight, also sometimes marketed as a "reading light" in order to appeal to the non-nerd as seen in the ReMarkable Paper Pro. [2] Frontlights are relatively uncommon overall. Electroluminescent lights present a reflective surface when turned off. This allows for a backlit display which can also be used with ambient light.

  3. Backlighting (lighting design) - Wikipedia

    en.wikipedia.org/wiki/Backlighting_(lighting_design)

    In photography, a back light (often the sun) that is about sixteen times more intense than the key light produces a silhouette. A fill flash used with a backlit subject yields more even lighting. The vertical angle of the back light can change the effect. A low angle can make the light hit the camera lens, causing lens flare. A high angle can ...

    en.wikipedia.org/wiki/Back-illuminated_sensor

    Comparison of simplified back-illuminated and front-illuminated pixel cross-sections. A back-illuminated (BI) sensor, also known as back-side illumination (BSI) sensor, is a type of digital image sensor that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance.

  5. Three-point lighting - Wikipedia

    en.wikipedia.org/wiki/Three-point_lighting

    Backlight is different from a kick or kicker in that it contributes to a portion of the shading on the visible surface of the subject. Backlighting provides the subject a rim of light, which separates the subject from the background and highlights contours. This creates a thin outline around the subject without necessarily hitting its front ...

    The diffused light then travels to either side of the diffuser; the front faces the actual LCD panel, the back has a reflector to guide otherwise wasted light back toward the LCD panel. The reflector is sometimes made of aluminum foil or a simple white-pigmented surface.

    The low and high beams, along with the position (parking) light and front turn signal, all use LEDs. The Lexus LS 600h (XF40) features LED low beam, position and side marker lights in North America, and the 2009 Cadillac Escalade Platinum used LEDs for the low and high beams, as well as for the position and side marker lights.

  8. Electroluminescence - Wikipedia

    en.wikipedia.org/wiki/Electroluminescence

    Views of a liquid crystal display, both with electroluminescent backlight switched on (top) and switched off (bottom). Electroluminescence (EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field.

  9. LED-backlit LCD - Wikipedia

    en.wikipedia.org/wiki/LED-backlit_LCD

    To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. The quantum dots may be in a separate layer as ...
