Title:
OLED DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2017/219462
Kind Code:
A1
Abstract:
An OLED display screen relates to the technical solution in the field of OLED display screens, comprising a first substrate (1), a second substrate (2), an OLED light emitting layer, and metallic signal lines (4). The first substrate (1) and the second substrate (2) are arranged opposite to each other. The OLED light emitting layer and the metallic signal lines (4) are all provided between the first substrate (1) and the second substrate (2). Light blocking layers (3) are provided between the first substrate (1) and the second substrate (2). All or some of the light blocking layers (3) are provided between the metallic signal lines (4) and the first substrate (1). The light blocking layers (3) are used for blocking incidence of natural light and/or blocking emergence of reflected light generated by the metallic signal lines (4). By means of the solution, the metallic signal lines (4) can be shielded by means of the light blocking layers (3), so that the reflected light of the metallic signal lines (4) is absorbed and it is unnecessary to provide a polarizer. The structure is simple, and light emitted by the OLED is not absorbed. Therefore, the light emission efficiency of the OLED display screen is greatly improved.
