Abstract
An organic light emitting diode (OLED) light source device is provided, including a lower substrate, a plurality of OLED modules disposed on the lower substrate and arranged in a matrix, a bus circuit surrounding the OLED modules to form a mesh structure and connecting the OLED modules in parallel, and an upper substrate disposed on the OLED modules and the bus circuit. The bus circuit connects the OLED modules in parallel. Therefore, the OLED light source device can be arbitrarily cut into different shapes, and its service life and light emitting performance are not affected by the cutting.
