PLASMA DISPLAY. 2. INTRODUCTION • A plasma display is a computer video display in which each pixel on the screen is illuminated by a tiny bit of plasma or charged gas, somewhat like a tiny neon light. • Plasma displays are thinner than cathode ray tube ( CRT ) displays and brighter than liquid crystal displays ( LCD ). Inside a Plasma Display. ­The xenon and neon gas in a plasma television is contained in hundreds of thousands of tiny cells positioned between two plates of glass. Long electrodes are also sandwiched between the glass plates, on both sides of the cells. The address electrodes sit behind the cells, along the rear glass plate.

The DHT22 is the more expensive version which obviously has better specifications. Its temperature measuring range is from -40 to +125 degrees Celsius with +-0.5 degrees accuracy, while the DHT11 temperature range is from 0 to 50 degrees Celsius with +-2 degrees accuracy. Also the DHT22 sensor has better humidity measuring range, from 0 to 100%

Disable the pico fuse or cut open the circuit trace (usually is the 12 to 14 volt line) if the board does not have pico fuse. After isolating the problem you can join back the circuit trace. Sometimes it also depends on the problem of the inverter board too and not necessary you have to cut open the circuit trace.
On the I2C module, you will find a potentiometer that you can turn with a small screwdriver. Plug in the USB connector of the Arduino to power the LCD. You should see the backlight light up. Now rotate the potentiometer until one (16×2 LCD) or 2 rows (20×4 LCD) of rectangles appear.
A change in voltage applied to liquid crystals changes the transmittance of the panel including the two polarizing plates, and thus changes the quantity of light that passes from the backlight to the front surface of the display. This principle allows the TFT LCD to produce full-color images. Structure of a TFT LCD

Cathode Ray Tube (CRT) Definition: The CRT is a display screen which produces images in the form of the video signal. It is a type of vacuum tube which displays images when the electron beam through electron guns are strik es on the phosphorescent surface. In other Words, the CRT generates the beams, accelerates it at high velocity and deflec t

How Do Liquid Crystal Displays Work? Unlike CRT monitors, LCD monitors cannot illuminate themselves, and so they require a light source: the backlight. This backlight is most frequently made of the well-known LEDs which stand for light-emitting diodes. Yvhg.
