METHOD AND DEVICE FOR DISPLAY COLOR ADJUSTMENT
Provided is a color adjustment method for a display apparatus. The color adjustment method includes: measuring first luminance coordinate data indicating a luminance and color coordinates of a color displayed on a display device when image data corresponding to a white point is supplied to a drive circuitry; measuring second luminance coordinate data indicating luminances and color coordinates of colors displayed on the display device when image data corresponding to the white color of intermediate grayscale values are supplied to the drive circuitry; measuring third luminance coordinate data indicating a luminance and color coordinates of a color displayed on the display device for each of R, G and B elementary color points when image data corresponding to each of the R, G and B elementary color points is supplied to the drive circuitry; and calculating correction parameters based on the first to third luminance coordinate data.
Liquid crystal display device and method for driving same
The present invention provides a liquid crystal display device capable of suppressing a decrease in display quality when pause drive is performed in an alternating-voltage drive mode, as well as a method for driving the same. In a first drive frame, overshoot drive is performed using correction values provided by an LUT to apply overshoot voltages whose absolute values are higher than absolute values of signal voltages to data signal lines. Subsequently, in a second drive frame, normal drive is performed to write signal voltages of the same polarity as the overshoot drive voltages to the data signal lines. Thereafter, a pause period in which an image written by normal drive is displayed continues until the start of a drive period in the next pause drive period. As a result, a decrease in luminance immediately after the signal voltages are written during the second drive frame is suppressed significantly, so that the viewer barely recognizes flicker.
Streamlined handling of monitor topology changes
Transitions between monitor configurations may be streamlined by minimizing the tearing down and recreating of render targets and primary frame buffers associated with the monitors. In at least one example, the techniques described herein include identifying at least one render target in a first monitor configuration that is also in a second monitor configuration. In response to identifying the at least one render target in the first monitor configuration that is also in the second monitor configuration, the techniques herein describe maintaining the at least one render target during a transition between the first monitor configuration to second monitor configuration.

DISPLAY APPARATUS
A display apparatus includes a pixel array, an optical modulator, a controller, and at least one memory device storing a frame memory. The optical modulator modulates the light emitted from the pixel array to corresponding angles. The controller generates images of a scene with different lighting profiles corresponding to different viewing angles according to information stored in the frame memory. The frame memory stores color information and material information of objects in the scene. The display apparatus displays the images through the first pixel array at the same time.
Graphics processing systems
When rendering a frame, e.g. that is to be used for rendering subsequent frames to be rendered, two versions of the frame are rendered, and sets of information representative of the content of the versions of the frame are compared to determine whether the first and second versions of the frame match or not. When the comparison determines that the two versions of the frame match, the frame is, e.g. used for rendering subsequent frames, but when the comparison determines that the two versions of the frame do not match, an error operation is performed.
