A flat-panel display (FPD) is an electronic viewing technology used to enable people to see content (still images, moving images, text, or other visual material) in a range of entertainment, consumer electronics, personal computer, and mobile devices, and many types of medical, transportation and industrial equipment. They are far lighter and thinner than traditional cathode ray tube (CRT) television sets and video displays and are usually less than 10 centimetres (3.9 in) thick. Flat-panel displays can be divided into two display device categories: volatile and static. Volatile displays require that pixels be periodically electronically refreshed to retain their state (e.g., liquid-crystal displays (LCD)). A volatile display only shows an image when it has battery or AC mains power. Static flat-panel displays rely on materials whose color states are bistable (e.g., e-book reader tablets from Sony), and as such, flat-panel displays retain the text or images on the screen even when the power is off. As of 2016, flat-panel displays have almost completely replaced old CRT displays. In many 2010-era applications, specifically small portable devices such as laptops, mobile phones, smartphones, digital cameras, camcorders, point-and-shoot cameras, and pocket video cameras, any display disadvantages of flat-panels (as compared with CRTs) are made up for by portability advantages (thinness and lightweightness).

Optical Data Transmission Using a Power Tool Device
PendingUS20250141247A1Batteries data exchangeCircuit monitoring/indicationPhotodetectorElectrical battery
Data are optically transmitted from a power tool device, such as a power tool, a power tool battery charger, power tool pack adapter, and / or a battery pack. The data are stored in a memory of the power tool device and are encoded as optical signal data to provide an encoded representation of the stored data. An optical transmitter (e.g., a light emitting diode or a flat panel display) transmits the optical signal data, which are detected or otherwise received by an optical receiver device, which may include a camera or other photodetector. The optical signal data may include light signals generated by an LED, where the data are encoded using an encoding scheme that modulates one or more characteristics (e.g., amplitude, wavelength, color) of the generated light signals. The optical signal data may also include images (e.g., barcodes, QR codes) or characters.
