Reader O f f er Grab a full HD 1920x1080 transparent display kit! This month, Crystal Display is giving away a full HD 21.5” transparent display panel complete with its metal frame housing, an industrial interface card and a custom power supply, worth $1300, for EETimes Europe’s readers to win. The display comes as an alternative to Samsung’s LTI220MT02 transparent LCD panel which are no longer produced by the manufacture. This translucent display offers a really interesting concept for the point-of-sale market place as well as unique applications such as transparent showcases and kiosks and could set a new standard for POS display. The sunlight-readable display is supplied with a compatible HD media player or a compatible interface kit including USB and HDMI inputs. There is an option for a multi-touch IR touchscreen capability too.

They are designed for applications where temperature stabilization of sensitive optical components is critical. The use of the circuit board improves the heat pumping capabilities of the device while providing excellent heat spreading, improved reliability and lower cost in high volume when compared to traditional heat removal systems. Tlam is used in applications where the components in the circuit produce a lot of heat, such as high powered LEDs, power supplies or motor drives. The Tlam circuit boards feature a thin layer of thermally conductive dielectric material sandwiched between a top layer of standard copper foil and a thick metal backing plate for structural strength and improved heat spreading. The combination of the Tlam circuit board with the thermoelectric offers a completely new way to design thermal rejection systems and can reduce the complexity of moving heat away from sensitive devices. The Tlam OptoTEC series includes seven new modules that can create a temperature differential (ΔT) of up to 67°C and pump from 1.5 to 9.0 watts of heat at an ambient temperature of 25°C. At 85°C, the series can create a ΔT of 77°C and pump 1.6 to 9.9 watts of heat. Laird www.lairdtech.com RGB digital light sensor automatically tunes displays brightness The ISL29125 RGB digital light sensor from Intersil helps engineers optimize the display resolution and colour quality of mobile devices and TVs in all lighting environments. The chip communicates directly with a device’s core processor to enable the automatic adjustment of display brightness based on changing light conditions, providing consumers with a crisp and colour consistent experience while extending battery life. The chip comes as a 6-lead 1.65x1.65x0.75mm RGB sensor. With integrated, robust on-chip IR filtering technology and an angular response of a minimum of +/- 35% field of view at 50% light intensity, the ISL29125 RGB sensor eliminates display fluctuations, whether one is in an incandescent lit classroom, an LED lit store or outdoors in the sun. More specifically for organic light-emitting diode (OLED) display TV applications, the ISL29125 can be used to adjust the blue organic material ageing profile to maintain consistent contrast and brightness throughout the life of the display. The IC operates from 2.25 to 3.63V, it has a wide dynamic range of 5.7m lux to 10k lux detection capabilities. In power down mode, the RGB sensor consumes less than 0.5uA of current and on active mode it runs at approximately 85uA. Intersil www.intersil.com AFE block serves as I/V converter for sensors Fabless analog chip company JVD Inc working with partner Systemcom Ltd has developed an analog front end (AFE) intellectual property block designed to condition signals from sensors where the proportional output of the transducer is current. Apart from that restriction, the block is designed to be suitable for a variety of sensor applications based on optical, mechanical, chemical and other methods. The block is available for license for inclusion in ASICs and system chips. It is intended for applications ranging from optically based monitoring through medical, and life-science systems up to consumer smartphones and onto industrial applications. The Si310 converts current captured from the sensor system to a differential output voltage, ready to be amplified. The current to voltage conversion is achieved using a proprietary transimpendance amplifier (TIA) architecture with 8 digitally programmable current ranges, extending from 8 microamps up to 1 milliamp in binary increments making the block suitable for connection to a wide variety of sensors with varying full-scale current outputs. One of the functionalities that the SCi310 provides is maintaining constant voltage at the input pin for all operating modes and input currents. This useful when biasing PIN diodes in the photoconductive region. The IP block can measure input current values in the range of hundreds of picoamps up to 1 milliamp.
