Abstract

An OLED display screen belonging to an OLED display screen technical field includes a first substrate, a second substrate, an OLED light-emitting layer and a metallic signal line. The first substrate and the second substrate are disposed opposite. The OLED light-emitting layer and the metallic signal line are both disposed between the first substrate and the second substrate. A light block layer is disposed between the first substrate and the second substrate. All or a section of the light block layer is disposed between the metallic signal line and the first substrate. The light block layer is applied to prevent incidence of natural light and/or reflective light generated by the metallic signal line. The disclosure can shelter the metallic signal line by the light block layer to absorb reflective light of the metallic signal line, a polarizer can be omitted. The structure is simple and illuminous efficiency is improved.

Dependent claims

An OLED display screen, comprising a first substrate, a second substrate, an OLED light-emitting layer and a metallic signal line, the first substrate and the second substrate being disposed opposite, the OLED light-emitting layer and the metallic signal line being disposed between the first substrate and the second substrate, a light block layer being disposed between the first substrate and the second substrate, all or a section of the light block layer being disposed between the metallic signal line and the first substrate, and the light block layer being a material of preventing incidence of natural light and/or emission of reflective light generated by the metallic signal line,

wherein the OLED light-emitting layer is an RGB light-emitting layer, the RGB light-emitting layer comprises a red light emitter, a green light emitter and a blue light emitter, the red light emitter, the green light emitter and the blue light emitter are disposed abreast and separately,
and, wherein a mounting groove is formed between two of the red light emitter, the green light emitter and the blue light emitter respectively, the metallic signal line is disposed in the mounting groove.

Dependencies are inferred from the claim text.
