Modern vehicles have most of their sensors and control modules monitored directly by the engine ECU. Each section of the cluster used to have direct inputs from the measured component (the fuel gauge, for example, would be wired directly to the fuel sender in the vehicles tank) however with the advent and application of the engine management ECU in the late 1980’s this changed.

Warning lights – appear as forewarning/notification that action needs to be taken including: seatbelt, low oil, low tyre pressure, engine management (EML), ABS and traction control and airbag SRS (supplemental restraint system) warnings etc.Īs automotive technology advances, the dashboard instrument cluster evolves at the same time.

Indicator lights – lights that show when a specific function is in use such as: turn signals, high beam, hazard and parking brake etc.

Trip meter (trip odometer) – can be reset at any point, measures and displays distance the vehicle has travelled after resetting the counter.

Odometer (odograph) – measures and displays the total distance the vehicle has travelled.

A high or low reading may show if the vehicles performance is substandard.

Engine coolant temperature gauge (Temp gauge) – indicates the temperature condition of the engine coolant.

Hybrid and fully electric vehicles have a display showing the ‘state of charge’ of the battery along with the estimated range (distance) left before recharge is required.

Fuel gauge – displays the remaining amount of petrol or diesel in the fuel tank.

Tachometer (rev counter/RPM gauge) – measures and displays the rate of rotation of the engines crankshaft allowing the driver to make informed decisions on throttle activation and expected gear selection.Speedometer (speedo) – measures and displays the current vehicle speed.These LCD TVs with LED backlighting are technically still LCD TVs, but some have dubbed them 'LED TVs,' to emphasize the LED backlights.An instrument panel typically comprises of the following components: But more recently the backlighting has changed to the brighter and more luminous LED (light emitting diode) technology lighting. The backlighting until recently has been traditionally CFL flourescent backlighting. The type of backlighting is the determining factor in what people today call LED TVs.

What type of Backlighting does an LCD TV have? Hence the 'liquid' part of the crystal's moniker: Rather than being an oxymoron (How can a solid also be a liquid?), the term refers to the relative pliability of the crystals themselves, which is to say, their twistability. A particular feature of this crystal is that it reacts to electric currents in predictable ways-i.e., by untwisting to varying degrees depending on the voltage of the current to which it is exposed. It has a naturally twisted crystalline structure. The twisted nematic (TN) liquid crystal is the most common type of liquid crystal being used in display applications today (e.g., LCD televisions, LCD monitors, and LCD projectors). But how does it work? What makes a crystal 'liquid'? Liquid crystal technology has given birth to those slim, cool-looking, bright displays that are popping up everywhere from bank lobbies to living rooms.

This technology is utilized in digital clocks, microwave ovens, car dashboards, calculators, stereos, thermometers, and even some bathroom scales! The applications for liquid crystal displays are almost limitless, so it should come as no surprise that this technology has revolutionized the most basic home appliance of all-the television set. Liquid crystal displays so prevalent, in fact, that most people couldn't get through their day without using one.
