Multi primary color display device and method of driving the same

摘要

A display device is configured for two-field sequential operation using a multi-colored backlight and an array of selectable filters where the array includes a subpixel repeat group having more than three non-white colors. The display device includes: an array of filters for defining pixels of an image, wherein each subpixel repeat group in the array comprises at least four non-white filters and at least one white filter; a backlight module comprising an array of at least four non-white light emitting diodes; and a control unit configured to operate the array of filters and the backlight module in a two-field sequential operation scheme such that for each subpixel repeat group in the array, most of the filters are usable (for having valved light passed therethrough) in both fields, two of the filters are usable on a mutually exclusive, and at least one filter is usable only in one of the fields.

1. A display device comprising a backlighting panel and a light-valving panel configured for producing images, wherein:
the backlighting panel is operatively coupled to the light-valving panel such that lights from different light sources included in the backlighting panel can be simultaneously and mixedly supplied to respective ones of repeat group areas of the light-valving panel, and wherein the light-valving panel includes:
a respective array of individually controlled light-valving cells;a respective array of differently colored or uncolored filters respectively overlapping the respective and individually controlled light-valving cells, said differently colored ones of the filters comprising at least four differently colored non-white filters and said uncolored filters comprising at least one white or clear filter, each combination of filter and corresponding light-valving cell defining a respective Filtered Optical Valve Unit (FOVU) through which can pass a correspondingly filtered portion of the backlighting supplied thereto from the backlighting panel, with plural ones of said FOVU's being respectively grouped into each of said repeat group areas of the light-valving panel, each repeat group area defining a pixel and having a repeating same color pattern of said FOVU's; and wherein the backlighting panel includes:
a respective backlight module comprising an array of said different light sources where the array includes at least four non-white and differently colored as well as individually controlled light sources; and wherein the display device further comprises: a control unit operatively coupled to, and configured to selectively operate the respective array of light-valving cells and the respective backlighting module in accordance with a two-field sequential operation scheme such that:
a first subset of at least two of the differently colored FOVU's of each corresponding repeat group area are operable in both of the two fields, anda second subset of at least two others of the differently colored FOVU's of each corresponding repeat group area are only operable on a mutually exclusive basis over the respective two fields.
