Explain the process of making of LCD
An LCD is made with either a passive matrix or an active matrix (a polysilicate layerprovides thin film transistors at each pixel, allowing direct pixel access and constantillumination) display grid. The active matrix LCD is also known as a thin film transistor(TFT) display. The passive matrix LCD has a grid of conductors with pixels located ateach intersection in the grid. A current is sent across two conductors on the grid tocontrol the light for any pixel. An active matrix has a transistor located at each pixelintersection, requiring less current to control the luminance of a pixel. For this reason, thecurrent in an active matrix display can be switched on and off more frequently,improving the screen refresh time. For example, mouse will appear to move moresmoothly across the screen.
