Light source device

Abstract

The invention discloses a light source device, comprising a light transparent substrate and a plurality of first metal wires, wherein the light transparent substrate includes a light emitting region and a peripheral region, the light emitting region includes a plurality of light emitting sub-regions, the plurality of metal wires are arranged on the light transparent substrate, one end of each of the metal wire is respectively connected with each light emitting sub-region and the other end is connected with the peripheral region. Each light emitting sub-region includes an insulated layer, a second metal wire and an organic light emitting diode layer, wherein the second metal wire is arranged between the light transparent substrate and the organic light emitting diode layer, the insulated layers are arranged between the first metal wires and the second metal wires, each of the first metal wires is overlapped with each second metal wire in the vertical projection direction, furthermore, one of the first metal wires passes through another light emitting sub-region. The aperture ratio or the light emitting area of the light source device can be increased effectively by using the light source device of the organic light emitting diode provided by the invention based on the design that the first metal wires are overlapped with the second metal wires.

Description

technical field [0001] The present invention relates to a light source device, and in particular to an organic light emitting diode light source device. Background technique [0002] In the application of organic light-emitting diode (OLED) as a light source device or backlight of liquid crystal display panel (LCD), when a large light-emitting area needs partition display, it is often necessary to divide the light-emitting area into several sub-areas, and each sub-area Each area pulls out a signal line to the drive circuit or drive circuit board, so that there is a way to achieve the purpose of separately controlling the brightness of each area. [0003] However, metal signal lines are opaque materials, which will affect the overall light-transmitting area, resulting in a decrease in the aperture ratio of the light-emitting device. Please refer to Figure 12 , shows a conventional organic light emitting diode light source device 50, the light emitting area 52 of the light s...

Problems solved by technology

However, blindly reducing the line width of the metal signal line will only increase the impedance of the signal line, increase the load on the metal signal line, and increase the overall power consumption, which cannot really solve the problem
