摘要： Methods and apparatus are provided for compensating a liquid crystal display for changes in brightness level. The apparatus comprises a variable brightness back-light optically coupled to a display panel whose properties depend upon back-light brightness. An electrical circuit measures back-light brightness and/or display flicker and sends this information to a controller. The controller automatically determines a display panel compensation signal based on back-light brightness and/or display flicker, and sends this compensation signal to the display panel to optimize the display panel properties for the commanded or observed back-light brightness level or flicker level so as to, for example, minimize display panel flicker and/or ghost image retention. Such automatic compensation is especially useful for head-up displays that must accommodate large variations in display brightness, e.g., from starlight to full sun, and/or for large, bright projection displays adapted to operate in different ambient light conditions where back-light brightness variation is desirable.
摘要翻译：提供了用于补偿液晶显示器以改变亮度水平的方法和装置。该装置包括光学耦合到显示面板的可变亮度背光，其特性取决于背光亮度。电路测量背光亮度和/或显示闪烁，并将该信息发送到控制器。控制器根据背光亮度和/或显示闪烁自动确定显示面板补偿信号，并将该补偿信号发送到显示面板，以优化指示或观察的背光亮度级别或闪烁级别的显示面板属性，例如，最小化显示面板闪烁和/或重影图像保持。这种自动补偿对于必须适应显示亮度的大变化（例如从星光到完全太阳）的平视显示器和/或用于适于在背光亮度不同的环境光条件下操作的大型明亮投影显示器的平视显示器特别有用变化是可取的。

摘要： A system and method for optimizing image uniformity in a head-up display (HUD) are provided. An imaging subsystem is characterized in that if light of a first uniformity is propagated therethrough, an uncompensated image would be displayed to a user via uncompensated image light. The uncompensated image light has first and second portions with respective first and second values of a radiant property. A difference between the first and second values is a first amount. The light source is configured to emit source light of a second, predetermined uniformity through the imaging system such that a compensated image is displayed to the user via compensated image light. The first portion of the compensated image light has a third value of the radiant property, and the second portion of the compensated image light has a fourth value of the radiant property. A difference between the third and fourth values is less than the first amount.
