LED backlight driver til store displays i biler
Med sigte på store automotive displays lancerer Maxim ny LED backlight driver med integreret LCD bias i en særdeles kompakt formfaktor (in english).
Automotive infotainment designers can now upgrade to bigger, higher resolution displays with greater ease, reduced cost and smaller solution size with the MAX20069 from Maxim Integrated Products. The MAX20069 provides the industry’s first solution integrating four I2C-controlled, 150mA LED backlight drivers and a four-output thin-film-transistor liquid-crystal display (TFT-LCD) bias in a single chip. The IC can reduce design footprint up to one-third compared to the closest competitor’s parts.Automotive displays are growing larger and more sophisticated as vehicle manufacturers lure buyers with greater information and entertainment options. Market research suggests a 39 percent compound annual growth rate for the 8-inch display market in vehicle instrument clusters, center stack and heads-up display systems. Instrument clusters are expected to migrate to 12.3-inch displays soon. As a result, automotive infotainment system designers will require power solutions with precision, flexibility and small overall solution size to meet increasingly complex system requirements.
MAX20069 supports larger screen sizes and higher resolution by providing positive analog supply voltage (PAVVD) and negative analog supply voltage (NAVDD), both of which are required for low-temperature polysilicon panels (LTPS) that deliver higher resolution and lower cost than amorphous silicon panels now currently in use. The IC also supports the high currents that next-generation displays require, with 150mA per channel in the four-channel LED driver for 8-inch or larger displays and higher resolutions. MAX20069 operates over the minus 40-degree Celsius to 105-degree Celsius ambient temperature range and is available in a 6mm x 6mm TQFN package.
- Automotive manufacturers are using more screens, larger panels and brighter displays across several vehicle lines to support a safer and more engaging experience on the road, says Szukang Hsien, executive business manager, Automotive Business Unit, Maxim Integrated.
- Maxim’s integrated LED backlight driver and TFT-LCD bias solution supports newer panel types to help automotive manufacturers adopt lower cost yet higher resolution panels with smaller solution size and a high level of integration.
