Display modules are integrated circuits that provide the user with an output display device. They typically have a number of inputs which can be used to control the display information as well as other features such as contrast adjustment, touch screen support, audio output, backlighting and data logging capabilities. Display modules are often referred to as graphic display controllers. Examples are LCD, OLED and TFT display modules. They typically combine a controller integrated circuit with a display panel, projector assembly and other components to provide a full display solution. Display modules are used in many consumer electronic products such as mobile phones, digital cameras, MP3 players and wearable devices.
