2. Backlight - Wikipedia

   en.wikipedia.org/wiki/Backlight

   A backlight is a form of illumination used in liquid-crystal displays (LCDs) that provides illumination from the back or side of a display panel. LCDs do not produce light by themselves, so they need illumination (ambient light or a special light source) to produce a visible image.

3. 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 ...

4. Liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_display

   The LCD itself is only a light valve and does not generate light; the light comes from a backlight that is either fluorescent or a set of LEDs. Brightness is usually stated as the maximum light output of the LCD, which can vary greatly based on the transparency of the LCD and the brightness of the backlight.

5. Bloom (shader effect) - Wikipedia

   en.wikipedia.org/wiki/Bloom_(shader_effect)

   Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...

6. Test light - Wikipedia

   en.wikipedia.org/wiki/Test_light

   A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.

7. The safest cars in 2025 - AOL

   Airbags, advanced driver assistance features, and high-strength materials mean that the safest cars today are far better at protecting people from injuries than ever before. Although most new cars ...

8. Contrast ratio - Wikipedia

   en.wikipedia.org/wiki/Contrast_ratio

   An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...

9. TFT LCD - Wikipedia

   en.wikipedia.org/wiki/TFT_LCD

   A thin-film-transistor liquid-crystal display (TFT LCD) is a type of liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. [1]
