Kopin Granted Two Key Patents on OLED Backplane Design


Patents Enable Higher Frame Rates and Lower Power Consumption of High-Resolution Displays for VR/AR/MR Applications

Kopin Corporation (Nasdaq: KOPN), a leading provider of innovative microdisplays for wearable computing applications, today announced that it was granted two US patents (10,304,372 and10,636,347) on “Two Rows Driving Method For Micro Display Device.” The technology described in the patents are especially important for designing backplanes of high-resolution OLED microdisplays desired for virtual reality (VR), augmented (AR) and mixed reality (MR) applications since it allows lower power consumption and high frame rates (120 Hz) to avoid motion sickness.

The key claims of the patents relate to simultaneously writing pixels in two separate rows of the display array during one ramp amplifier cycle. In prior arts, pixels in only one row can be written while all the columns are being driven by the ramp. In the patented method, one half of the pixels in each column of the display array are connected to one set of rows while the other half connected to the other set of rows. The first half pixel columns are connected to a ramp amplifier while the second half pixel columns are connected to another ramp amplifier. This allows pixels in the two rows in the two different sets to be written simultaneously but also independently.

Driving two rows for each cycle of the ramp signal can reduce the ramp frequency by half, which in turn lowers the power consumption of the ramp amplifier by half. This is important because the ramp amplifier consumes a significant portion of the overall display power in high resolution displays. In addition, doubling the ramp period relaxes the timing requirements of the pixel driver circuits, which become increasingly more challenging for 120 Hz operation of higher resolution displays. As an example of the benefits, the maximum backplane power for our Lightning® 2k (2048 x 2048 resolution) OLED microdisplay is only about 450 mW at 120 Hz operation – this is about 300 mW lower than if a single row drive method were used.

“We are delighted to have these two patents granted,” said Dr. John C.C. Fan, CEO of Kopin Corporation. “Our innovative double-rows driving architecture is incorporated in our Lightning 2k and 2.6k (2560 x 2560 resolution) OLED displays. With enhanced performance thanks to this patented method, we believe our OLED displays will play critical roles in realizing lifelike VR/AR/MR systems that are highly desirable in an increasingly contactless social trend.”
