Abstract

An electroluminescent device comprises a substrate, a pixel array, a plurality of lead groups, a plurality of driving devices and at least one power supply transmission pattern, wherein the substrate comprises a display area and a peripheral circuit area arranged on the periphery of the display area; the pixel array is arranged in the display area of the substrate and provided with a plurality of pixel structures, each pixel structure contains at least one active element and at least one light-emitting element which is electrically connected with the active element; the lead groups are arranged in the peripheral circuit area of the substrate and are electrically connected with the pixel array, wherein each lead group contains a plurality of leads; each driving device is electrically connected with one lead group; and the power supply transmission pattern is arranged in the peripheral circuit area of the substrate and positioned between adjacent two lead groups, wherein one end of the power supply transmission pattern is electrically connected with the light-emitting element of the pixel array and the other end of the power supply transmission pattern is electrically connected with the corresponding driving device.

Description

Technical field [0001] The present invention relates to a light emitting device, and in particular to an electroluminescent device. Background technique [0002] The electroluminescent device is a self-luminous (Emissive) device. Because the electroluminescent device has no viewing angle limitation, low manufacturing cost, high response speed (approximately more than a hundred times that of liquid crystal), power saving, DC drive that can be used in portable machines, large operating temperature range, light weight and easy Miniaturization and thinning of hardware equipment, etc. Therefore, electroluminescent devices have great development potential and are expected to become the next generation of novel flat-panel displays. [0003] Generally speaking, an electroluminescent device is composed of an upper electrode layer, a lower electrode layer, and a light-emitting layer sandwiched between the two electrode layers. The lower electrode layer is generally made of transparent cond...
