    • A laser display apparatus is provided to reduce a speckle by equalizing a speckle contrast through overlapping the speckle generated in the laser display apparatus. A laser display apparatus includes a laser illumination system(10), a laser scanning unit, and a speckle reducing unit(50). The laser illumination system has at least one laser beam(L). The laser scanning unit scans the laser beam emitted from the laser illumination system to form an image. The speckle reducing unit includes a beam separating element and an optical path switching member. The speckle reducing unit irradiates the laser beam scanned from the laser scanning unit. The beam separating element separates the inputted laser beam into a plurality of partial laser beams(L1,L2). The optical path switching member allows the separated laser beams to be irradiated at different angles.
    • 提供了一种激光显示装置,通过使激光显示装置中产生的斑点重叠来均衡散斑对比度来减少斑点。 激光显示装置包括激光照射系统(10),激光扫描单元和散斑减少单元(50)。 激光照明系统具有至少一个激光束(L)。 激光扫描单元扫描从激光照射系统发射的激光束以形成图像。 散斑减少单元包括光束分离元件和光路转换元件。 斑点减少单元照射从激光扫描单元扫描的激光束。 光束分离元件将输入的激光束分离成多个部分激光束(L1,L2)。 光路切换构件允许分离的激光束以不同的角度照射。

    • A projection display device is provided to display a color image at an improved light efficiency by using a line type light modulator. A projection display device includes a lighting unit, a scroll unit(120), a line type light modulator(130) and a scan unit(150). The lighting unit irradiates plural linear beams, which are parallel to each other. The scroll unit scrolls the linear beams. The line type light modulator modulates the linear beams according to an image signal. The scan unit irradiates the linear beams in a scroll direction and a normal direction. The lighting unit includes a laser source and a beam former. The laser source irradiates plural beams. The beam former converts the beams into plural linear beams with a predetermined width.
