One of most rapidly developmentand socially significant areas of a national economy are energy prezerving lighting technologies and technologies of tools of visualization (ToV). Now along with such «traditional» the ToV as cathode ray tube (CRT) and liquid crystal display (LCD), actively develop also modern technologies: plasma panels and light-emitting diode (solid-state) matrixes. The basic advantages of light-emitting diodes are: - high light output (more than 140 lm/Vt); - a high resource of work at high vibration - and crash-worthiness; ? low working voltage (to 10 V). Modern light-emitting diode technologies develop now in two basic directions: ? inorganic light-emitting diodes (LED - light emitting diode); ? organic light-emitting diodes (OLED/PLED - organic/polymer light emitting diode). In the present overwhelming majority (more than 98 %) lighting light-emitting diode devices are made on semi-conductor technology (LED), but last 5 years rapid development of «know-how» of organic light-emitting diodes (OLED/PLED) is ob-served. It first of all is connected with: - possibility of manufacturing of flexible matrixes of light-emitting diodes; - theoretically maximum limit light output which for LED makes 300 lm/wt, and for OLED - 360 lm/wt; - reduction of power inputs (working voltage LED makes 6 - 10 V, and OLED/PLED - 2 - 4 V); - decrease in the cost price of products at the expense of introduction of rolled technologies; - high picture contrast (1000000:1), providing formation the image at bright illumination (more than 1000 lux). In work comparison of the basic technologies of formation of white colour on the basis of light-emitting diodes and the cores of technologies of formation of the colour image (for the ToV), their basic merits and demerits is presented. It is shown, that selecting materials and structure of an organic light-emitting diode it is possible to make panels (matrix) practically any areas and forms (including and volume), lengths of waves radiating in various ranges. Therefore, besides lighting technology and technology of the ToV, light-emitting diode devices are supposed to be used as means of a wireless information transfer (in a zone of direct visibility), as sensor controls of various devices (security systems, the fire alarm system, flexible keyboards for personal computers...), and also in home appliances (for example, for registration of interiors of rooms, in manufacturing of fur-tree garlands etc.). Universality and uniqueness of light characteristics of organic light-emitting diodes allows to assume increase in rates of development and introduction of the given technologies in the most various areas of a national economy and gradual replacement from the market of traditional means of illumination and the ToV.
