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.
Arduino layout-compatible board, designed for use with a USB-TTL serial cable. DuinoBot v1.x [89] ATmega32U4 RobotGroup Argentina [90] Arduino fully compatible board, with integrated power supply and controllers designed for robotics.

Arduino and Arduino-compatible boards use printed circuit expansion boards called shields, which plug into the normally supplied Arduino pin headers. [55] Shields can provide motor controls for 3D printing and other applications, GNSS (satellite navigation), Ethernet, liquid crystal display (LCD), or breadboarding ( prototyping ).
A drawing meant to depict the physical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram. Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment. In computer science, circuit ...
LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut. LCD TVs rose in popularity in the early years of the 21st century, and exceeded sales of cathode-ray-tube televisions worldwide from late 2007 on. [ 1 ]
A display device is an output device for presentation of information in visual [1] or tactile form (the latter used for example in tactile electronic displays for blind people). [2] When the input information that is supplied has an electrical signal the display is called an electronic display .
