What is a Computer Monitor? A monitor is the visual output device connected to the computer tower. It displays picture and images in real time, allowing one to interact with the computer, activating and running its programs at will. There are two primary types of computer monitors, each with their own advantages over the other. Front end of the LCD Module. This LCD module is the basic one and the most commonly-used character display; The voltage is 5V. The voltage level Arduino I/O Port uses is 5V so that we choose the LCD module. Besides, the LCD module can display 16 characters per line and there are 2 such lines. Also, the module uses I2C protocol. Edge-Lit LED. In an edge-lit television, the LEDs that illuminate the LCD pixels are located only along the edges of the set. These LEDs face inward toward the screen to illuminate it. These models are thin and light at the mild expense of some picture quality—specifically in the area of black levels. Black areas of the picture, such as a Start connecting the pins of Arduino to LCD as shown, 5V toVCC, GND to GND, ReadWrite to GND, Resister Select to pin 12, Enable to pin 11, DB4 to pin 5, DB5 to pin 4, DB6 to pin 3, DB7 to pin 2. Now connect the LED (-ve) to GND and LED (+ve) to 5V through 220ohms resistor. Connect the wiper of the potentiometer to the contrast pin (VO) of the In-plane switching is a type of panel technology for LCDs. The LCD panel technology is famous for offering high-quality and life-like images. Additionally, the panel technology provides better contrast and viewing angles than TN and VA panel technologies. IPS LCD monitors are also known to offer incredible color accuracy. Vay Tiền Trả Góp Theo Tháng Chỉ Cần Cmnd.
