摘要：
The paper presents the results of radiation measurement of super bright LED modules containing as a cylindrical lens a linear raster structure of Fresnel-lens type, intended for large information screens. Such linear raster structure may be applied for increasing OLED brightness. The causes of nonreproducibility of optical characteristics are analyzed using LC vision technique.
