摘要： Conventionally, in a display device using lasers, a blue light source having a relatively long wavelength and a red light source having a relatively short wavelength are adopted because a short-wavelength blue light source and a long-wavelength red light source cause degradation in visibility. Therefore, there are problems that an expressible color region is restricted, and large output power is required for white display. Accordingly, in a two-dimensional image display device of the present invention, the center wavelength of a red color source is set in a range from 635 nm to 655 nm and the center wavelength of a blue light source is set in a range from 420 nm to 455 nm, thereby obtaining a bright and clear image at minimum power consumption.
摘要翻译： 通常，在使用激光的显示装置中，采用具有较长波长的蓝色光源和具有较短波长的红色光源，因为短波长蓝色光源和长波长红色光源导致可见性降低 。 因此，存在可表现的颜色区域被限制的问题，并且白色显示需要大的输出功率。 因此，在本发明的二维图像显示装置中，将红色源的中心波长设定在635nm〜655nm的范围内，将蓝色光源的中心波长设定在420 nm至455nm，从而以最小功耗获得明亮清晰的图像。
