A color sequential liquid crystal display (LCD) device is disclosed in the present invention. The color sequential LCD device includes an LCD panel, a backlight module, an image processing circuit and a timing control circuit. The image processing circuit is utilized for performing image processing on an image data to generate a frame data with full color information, and sorting the frame data to generate a plurality of frame data based on a predetermined color sequence. The timing controller is utilized for controlling the LCD panel and the backlight module to display the plurality of field data outputted by the image processing circuit, so as to achieve color mixing in time domain.

In a line data sorting unit of a color sequential timing controlling circuit, inputted pixels/sub-pixels are buffered, sorted, and outputted. The pixels/sub-pixels are also sorted by a color data sorting unit according to the color sequential method and colors of sub-pixels so that a driving controller writes sorted sub-pixels of various colors onto a display panel within a short time variation to generate a full-color frame. The line data sorting unit buffers pixels/sub-pixels as a matrix, and loads the buffered pixels/sub-pixels line-by-line with respect to the matrix, where the pixels/sub-pixels are arranged and read in parallel according to sizes of lines of the matrix and a number of simultaneously-activated gate lines of a scanning driver.

Color sequential timing controlling circuit and both color sequential display system and method thereof

A light source module is provided. The light source module includes a reflector, a light source, a transparent cover, a fluorescent material layer, and an optical lens. The light source is disposed inside the reflector, and the light source is suitable for emitting light including white light. The light source is enveloped with the transparent cover and the reflector. The fluorescent material layer is disposed on the transparent cover and the light emitted from the light source is suitable for exciting the fluorescent material layer to emit red light. The optical lens is disposed on an optical path of the light source, and the transparent cover is located between the optical lens and the light source. By utilizing the aforementioned structures, the intensity of the red light can be increased. Moreover, an optical projection system is also provided.
