2. Hitachi HD44780 LCD controller - Wikipedia

   en.wikipedia.org/wiki/Hitachi_HD44780_LCD_controller

   The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 40 character lines. Using an extension driver, the device can display up to 80 characters. [1]

   The thickness of the inverter transformers also limits how thin the display can be made. EL-WLED: The LCD panel is lit by a row of white LEDs placed at one or more edges of the screen. A light diffuser (light guide plate, LGP) is then used to spread the light evenly across the whole display, similarly to edge-lit CCFL LCD backlights.

4. Dot-matrix display - Wikipedia

   en.wikipedia.org/wiki/Dot-matrix_display

   A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.

5. Twisted nematic field effect - Wikipedia

   en.wikipedia.org/wiki/Twisted_nematic_field_effect

   A high-resolution matrix LCD with required fast response (e.g. for animated graphics and/or video) necessitates integration of additional non-linear electronic elements into each picture element of the display (e.g., thin-film diodes, TFDs, or thin-film transistors, TFTs) in order to allow active matrix-addressing of individual picture elements ...

6. Passive matrix addressing - Wikipedia

   en.wikipedia.org/wiki/Passive_matrix_addressing

   Passive matrix addressing is an addressing scheme used in early liquid crystal displays (LCDs). It is a matrix addressing scheme, meaning that only m + n control signals are required to address an m × n display. A pixel in a passive matrix must maintain its state without active driving circuitry until it can be refreshed again.

7. TFT LCD - Wikipedia

   en.wikipedia.org/wiki/TFT_LCD

   The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs. [3]

8. STN display - Wikipedia

   en.wikipedia.org/wiki/STN_display

   A STN (super-twisted nematic) display is a type of liquid-crystal display (LCD). An LCD is a flat-panel display that uses liquid crystals to change its properties when exposed to an electric field, which can be used to create images. This change is called the twisted nematic (TN) field effect. Earlier TN displays twisted the liquid crystal ...

9. Active-matrix liquid-crystal display - Wikipedia

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

   An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and fast response time.
