Lead-free LCDs outperform the old wave

New lead-free panels meet impending environmental regulations, and also integrate extra features for higher performance compared with previous-generation equivalents.

New lead (Pb)-free panels from Trident Displays meet environmental regulations coming into force, and also integrate extra features for higher performance compared with previous-generation equivalents.

The Toshiba LTD121C30S is a 12.1in SVGA TFT-LCD, which has the same outline and mounting requirements as the previous LTM12C289.

As well as migrating to Pb-free, the new display now also integrates horizontal/vertical and compound sync on the same panel.

A wider operating temperature range of -10 to + 65C also allows use in industrial applications or other harsh environments.

The panel is rated at 7.0W power consumption, operates from 3.3V supply voltage, and features dual CCFL backlights The second new panel is the Toshiba LTD104C11S.

This is billed as the smallest footprint 10.4in display available, and also has the thinnest profile.

It features horizontal/vertical and compound sync on the panel, 640 x 480 VGA resolution, and dual 3.3/5.0V input voltage.

Rated power consumption is 6.2W.

Maximum luminance of 400cd/m2 ensures a bright display under all lighting conditions, even in direct sunlight, and the wide viewing angle of 120 degrees vertical and 140 degrees horizontal makes the display easy to read with little colour distortion at extreme angles.

The LTD104C11S is also suitable for operation over the wider -10 to +65C temperature range.

Both new panels have 6bit colour resolution, 47% colour gamut, and feature reverse scan capability.

MTBF for each is 50kh.
