LCD driver test system doubles throughput
Addressing a surge in demand for liquid crystal displays, the Advantest T6371 offers twice the throughput offered by previous test systems.
Memory test system more than doubles its speed
The Advantest T5375 memory test system is capable of testing up to 128 devices simultaneously at speeds of either 143 or 286MHz DDR.
The growth of media-rich consumer electronics such as web-enabled cell phones and PDAs has increased the need for thinner, lightweight displays that provide both faster response times and lower power consumption.
The majority of handheld consumer electronics currently on the market use either thin film transistor (TFT) or super-twist nematic (STN) LCD displays.
One drawback of these technologies, however, is that they require the use of backlights, which invariably increases the display's thickness.
In contrast, OLED displays are self-emitting, meaning that they do not require backlights or other external light sources and thus allow engineers to use thinner product designs.
Other advantages include faster response times, lower power consumption, and improved luminescence, all of which makes OLED displays an ideal candidate for use in next-generation, handheld consumer electronics.
In anticipation of this market's high growth potential, chipmakers are currently ramping up to large-scale production of the driver ICs used in these displays.
Testing of these devices, however, requires quick and accurate measurement of driver voltage, which first must be converted from the electrical current emitted by these devices.
The new option for the T6300 series of LCD driver test systems solves this problem by providing a current-voltage (I/V) convertor optimised for use in the testing of OLED drivers.
By reconfiguring this option into their test systems, Advantest customers will thus be able to expand their system's functionality to include testing of current-driven OLED drivers.
In addition, by achieving an up to 1000% reduction in characterisation times for driver linearity and settling time and by enabling parallel testing of two devices, this option also provides a twenty-fold improvement in the T6300's testing throughput for OLED drivers.
