Abstract

The invention belongs to the technical field of illumination of an organic light emitting diode, and discloses an alternating current driven white light OLED device. The white light OLED device comprises a first light emitting unit, a second light emitting unit and an electrode connecting layer positioned between the two light emitting units; the first light emitting unit and the second light emitting unit both give out white light; when the device is in use, the electrode connecting layer is connected with one end of an alternating current power supply; the first light emitting unit and the second light emitting unit are connected with the other end of the alternating current power supply separately to form two groups of parallel light emitting circuits; the first light emitting unit is driven in the positive period of an alternating current signal while the second light emitting unit is driven in the negative period of the alternating current signal to realize the alternating currentdriven white light OLED device, and a non-stroboscopic effect can be achieved; relatively stable white light can be obtained without depending relative sizes and frequency of positive and negative voltage signals; and in addition, by adoption of an inorganic light emitting material, the white light OLED device can be more diversified.

Description

technical field [0001] The invention belongs to the technical field of organic light-emitting diode (OLED) lighting, and in particular relates to an AC-driven white light OLED device. Background technique [0002] Organic light-emitting diode (OLED) is a lighting and display technology with great development prospects. It has very excellent performance. In the field of OLED lighting, the device has low calorific value, low power consumption, fast response, bendable, and impact resistance. At the same time, it has the characteristics of thinness, surface luminescence, and good ductility. It can abandon all lampshade designs, heat sink parts, etc., and can bring new design concepts to the lighting field. The application of OLED to the lighting field has a huge prospect. It is expected to become the mainstream of lighting in the future. [0003] With the development of semiconductor lighting technology, various light-emitting device structures have been proposed, and AC signal...
