Videodisplays

Videodisplays are devices and display panels that render electronic video signals into visible images. They are used in televisions, computer monitors, projectors, mobile screens, signage, and professional displays. Videodisplays convert electrical video data into light at the pixel level through various technologies and supply chains.

Historically, cathode ray tubes dominated; modern displays rely on liquid crystal displays (LCDs) with backlights, light-emitting diodes (LEDs) for illumination, organic light-emitting diode (OLED) panels, and newer microLED options. Other display types include plasma displays and projection-based systems using DLP or LCD projection.

Displays are characterized by resolution, aspect ratio, color depth, brightness, contrast, refresh rate, and response time. LCD-based panels use backlights and liquid crystals to modulate light, while OLED and microLED emit light at the pixel level. Interface standards such as HDMI, DisplayPort, and USB-C carry video signals from sources to displays. Refresh rates of 60 Hz, 120 Hz, or higher are common, especially for gaming and motion-critical applications.

Labeling and market use include consumer, professional, medical, and digital signage. Trends include higher resolutions, wider color gamuts, higher dynamic range (HDR), smaller bezels, and more energy-efficient designs. The term videodisplays covers integrated displays in devices and stand-alone panels.
