2. TFT LCD - Wikipedia

   en.wikipedia.org/wiki/TFT_LCD

   A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in television sets , computer monitors , mobile phones , video game systems, personal digital assistants , navigation systems ...

3. Active-matrix liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Active-matrix_liquid...

   Having supplanted passive-matrix LCDs in general use, in common vernacular, an active-matrix LCD is also simply referred to as a LCD. As of 2025, the term "AMLCD" is uncommon as a matter of technical jargon ; instead, due to their ubiquity, different types of active-matrix liquid crystal displays are usually specified — TFT LCD , IPS LCD ...

4. Liquid-crystal display - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_display

   An LED backlight for a handheld LCD device. LCDs do not produce light on their own, so they require external light to produce a visible image. [82] [83] In a transmissive type of LCD, the light source is provided at the back of the glass stack and is called a backlight. Active-matrix LCDs are almost always backlit.

5. Comparison of display technology - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_display...

   LCDs have a constant (backlit) image, where the intensity is varied by blocking the light shining through the panel. CRTs use an electron beam, scanning the display, flashing a lit image. If interlacing is used, a single full-resolution image results in two "flashes".

6. LED-backlit LCD - Wikipedia

   en.wikipedia.org/wiki/LED-backlit_LCD

   An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. [1] LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them. Televisions that use a ...

   Up to 120 in (3.0 m) [42] Up to 150 in (3.8 m) [43] (152 in experimental) [44] Up to 97 in (2.5 m) [45] Maintenance Hazardous to repair or service due to high-voltage, requires skilled convergence calibration and adjustments for geographic location changes. [46] Glass display tube is evacuated and carries risk of implosion if improperly handled.

8. Active matrix - Wikipedia

   en.wikipedia.org/wiki/Active_matrix

   Active matrix is a type of addressing scheme used in flat panel displays.It is a method of switching individual elements of a flat panel display, known as pixels.Each pixel is attached to a transistor and capacitor that actively maintain the pixel state while other pixels are being addressed, in contrast with the older passive matrix technology in which each pixel must maintain its state ...

9. Thin-film transistor - Wikipedia

   en.wikipedia.org/wiki/Thin-film_transistor

   AMOLED displays also contain a TFT layer for active-matrix pixel addressing of individual organic light-emitting diodes. The most beneficial aspect of TFT technology is its use of a separate transistor for each pixel on the display. Because each transistor is small, the amount of charge needed to control it is also small.
