Displays

Displays LED displays presents a somewhat unique set of design constraints and challenges. Instrument clusters require a certain amount of illumination to be clearly readable, and, as ambient lighting conditions change, the brightness of the backlight must be adjusted to compensate. It is essential that the dimming range of an LED/LED driver system is sufficiently wide to accomplish this. In addition to being compact and cost-efficient, LED driver ICs must withstand the harsh thermal, chemical, and electrical conditions of an automotive environment. Reliable current regulation over a range of environmental circumstances is critical for maintaining uniform brightness across the panel and for protecting the long operating life of an LED backlight.

Fiber Optics

Fiber Optics Fiber optics are flexible, transparent fibers that transmit light between it's two ends. They are used in communications, where transmission over long distances and higher bandwidths are possible. The extruded glass or plastic fibers are immune to electromagnetic interference and have less loss than metal wires.

High Power LEDs

High Power LEDs A High Power LED is an individual components that are greater than 0.20 watts, generally smaller in package size and find applications where traditional lighting sources will not fit.

LED

LEDs A LED is a semiconductor device that emits infrared or visible light when charged with an electric current. LEDs emit light wavelengths both visible and invisible when electrically charged. The color emitted is derived from the chemical composition of the semiconductor material used in manufacturing. LEDs are differentiated by their color/wavelength measured in units of nanometers (nm) or their color corrected temperature (CCT) measured in units of Kelvin (K). In addition, LEDs may consume lower power, provide longer lifetime, be more robust, and are able to be switched On/Off at very high rates of speed.

LED Indication

LED Indication LED indication products and solutions facilitate machine to human communication. Indication refers to the use of a light source that is to be viewed directly as a self-luminous object, such as in signs, signals, and indicator lights on electronic equipment. LED Indication also includes everything from mounting hardware to LED Drivers and light pipes, as well as other useful replacement parts.

Optocoupler / Photocoupler

Optocoupler / Photocoupler An optocoupler is a component that uses a short optical transmission path to transfer a signal between elements of a circuit, typically a transmitter and a receiver, while keeping them electrically isolated. An electrical signal is changed to an optical signal and then back to an electrical signal therefore breaking the electrical path, ie. isolating the circuits. Optocouplers are also known as opto-isolators and photocouplers. Many systems require signals and data to be transferred from one subsystem to another within electronics equipment without a direct electrical connection. Safety agencies require the isolation. Isolation is necessary when the source and destination circuits are operating at very different voltage levels. For example: A microprocessor operating at 5V DC is being used to control a circuit that is switching at 240V DC. The link between these two circuits is isolated to protect the microprocessor from overvoltage damage.

Things to Consider

Optocouplers / Photocouplers
  • Required CTR
  • Isolation requirement & isolation working voltage
  • What is the main electrical function?
  • Bandwidth & switching speed
LEDs
  • What color are you looking for?
  • How bright do you need the LED to be?
  • Which packaging suits your design needs? Through hole or surface mount?
  • Is an LED Driver needed?
