Rohm had two OLED items at CEATEC. The first is a 'shadowless' OLED lamp. The lamp is using a 'complex' array of OLED panels so that objects beneath it has no shadow.
The second item they had on display is an OLED Flash. The flash can emit light with a high luminance (100,000cd/m2). The flash can also be used as a 'regular' OLED lamp, with a luminance of of 3,000-4,000cd/m2 or higher.
