Abstract: An electronic device may be provided with a display mounted in a housing. The display may include a liquid crystal display module and a reflective polarizer having an in-plane optical axis. The display may also include a backlight unit that includes a light source, a light guide element, and a reflector film coupled to a backside of the light guide element. The display may also include a light retardation layer such as a quarter wave film. The quarter wave film may be arranged between the reflective polarizer and the reflector film of the backlight unit. Partially polarized light that is output from a front side of the light guide element may have a first component parallel to the in-plane optical axis and a second component perpendicular to the in-plane optical axis of the reflective polarizer. The second component may be reflected from the reflective polarizer.

Abstract: A display polarizer may have a polymer layer such as a polyvinyl alcohol layer coated with a dichroic dye such as iodine. A polymer layer such as a tri-acetyl cellulose layer may be formed on the polyvinyl alcohol layer so that the iodine is interposed between the polyvinyl alcohol layer and the tri-acetyl cellulose layer. To provide protection for the iodine layer, an additional polymer layer such as an additional tri-acetyl cellulose layer and a layer of adhesive may be formed on top of the polymer layer. A functional layer such as an antireflection layer may form an outermost layer in the polarizer. Compensation films may be formed beneath the polyvinyl alcohol layer. Additional display layers such as a lower polarizer layer and interposed layers such as a thin-film transistor layer, liquid crystal layer, and color filter layer may be formed below the compensation films.

Abstract translation: 显示器偏振器可以具有聚合物层，例如涂覆有二色性染料如碘的聚乙烯醇层。 可以在聚乙烯醇层上形成聚合物层，例如三乙酰纤维素层，以使碘介于聚乙烯醇层和三乙酰纤维素层之间。 为了提供对碘层的保护，可以在聚合物层的顶部上形成另外的聚合物层，例如另外的三乙酰纤维素层和粘合剂层。 诸如抗反射层的功能层可以在偏振器中形成最外层。 补偿膜可以形成在聚乙烯醇层之下。 可以在补偿膜的下方形成附加的显示层，例如下偏振器层和诸如薄膜晶体管层，液晶层和滤色器层的插入层。
