    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. During operation of the display, 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: An electronic device may have a housing in which a display is mounted. A gasket may be mounted in a groove between the display and housing. The gasket may contain an embedded stiffener. Corner brackets may be installed in the corners of the housing. The housing may have inner and outer concentric ribs. Recesses in the housing may be configured to receive the corner brackets. The recesses may be formed between the inner and outer concentric ribs. Gap filling structures such as a foam layer may be interposed between a rear housing wall and a display backlight unit. Display color variations may be corrected by using a backlight unit having an array of light-emitting diodes of different colors. An electrostatic discharge protection layer may be grounded to a housing using conductive tape. Black edge coatings and adhesive-based structures may block stray light. Camera window regions may be supported using adhesive.

    Abstract translation: 电子设备可以具有安装显示器的外壳。 垫圈可以安装在显示器和壳体之间的凹槽中。 垫圈可以包含嵌入式加强筋。 角支架可以安装在外壳的角部。 壳体可以具有内部和外部同心肋。 壳体中的凹陷可以被配置成接收角落托架。 凹部可以形成在内部和外部同心肋之间。 间隙填充结构例如泡沫层可以插入在后壳体壁和显示器背光单元之间。 可以通过使用具有不同颜色的发光二极管阵列的背光单元来校正显示颜色变化。 静电放电保护层可以使用导电带接地到壳体。 黑色边缘涂层和基于粘合剂的结构可能会阻挡杂散光。 可以使用粘合剂来支持相机窗口区域。
