Abstract
The invention provides a flexible display and method for fabricating the same. The flexible display includes: a first flexible substrate and an oppositely disposed second flexible substrate; a TFT layer and an emitting unit, sequentially formed on the first flexible substrate; a color filter layer and an overcoat formed on the second flexible substrate; a fill formed between the first flexible substrate and the second flexible substrate; and a dam formed between the first flexible substrate and the second flexible substrate and surrounding the fill.
Claims19
A method for fabricating flexible displays, comprising:
- providing a first rigid carrier substrate, wherein a first de-bonding area, a first flexible substrate, a thin film transistor layer, and a light emitting unit are formed on the first rigid carrier substrate;
- providing a second rigid carrier substrate, wherein a second de-bonding area, a second flexible substrate, and a color filter layer are formed on the second rigid carrier substrate;
- performing a first cutting step to cut the second de-bonding area and the second flexible substrate, wherein the second flexible substrate is divided into a first portion and a second portion;
- assembling the first rigid carrier substrate and the second rigid carrier substrate together;
- fixing the first rigid carrier substrate, and separating the second de-bonding area from the first portion of the second flexible substrate to expose a surface of the first portion of the second flexible substrate, and removing the second rigid carrier substrate and the second de-bonding area;
- performing a second cutting step to cut the first de-bonding area and the first flexible substrate, wherein the first flexible substrate is divided into a third portion and a fourth portion, and the thin film transistor layer is formed on the third portion of the first flexible substrate;
- and
- separating the first de-bonding area from the third portion of the first flexible substrate, and removing the first rigid carrier substrate and the first de-bonding area to form the flexible display.
A flexible display, comprising:
- a first flexible substrate and a second flexible substrate, wherein the first flexible substrate is disposed oppositely to the second flexible substrate;
- a thin film transistor layer and a light emitting unit formed on the first flexible substrate;
- a color filter layer formed on the second flexible substrate;
- a sidewall barrier layer (SWB layer) formed between the first flexible substrate and the second flexible substrate, wherein the color filter layer and/or light emitting unit is surrounded by the sidewall barrier layer, wherein a height of the sidewall barrier layer is higher than that of the color filter layer;
- an overcoat formed on the sidewall barrier layer (SWB layer) and on the color filter layer;
- and
- a fill formed between the light emitting unit and the color filter.
