20220036864 · 2022-02-03 ·

The present teaching relates to method, system, medium, and implementations for LED display. A first signal is received that signals a timing for a next data transfer. In response to the first signal, a bit-based image block stored in a memory is transferred, via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer, which is subsequently toggled to point to another of the pair of alternate buffers. A second signal is received that signals a timing for refreshing the LED display. In response to the second signal, the bit-based image block is retrieved from the one of the pair of alternate buffers pointed to by a read buffer pointer, which is then toggled to point to the other of the pair of alternate buffers. The lights of the LED display are then refreshed in accordance with control signals generated based on the bit-based image block.

The present teaching relates to method, system, medium, and implementations for data transfer in LED display. A signal signaling a timing for a next data transfer is received. In response to the signal, a next data transfer instruction is obtained that instructs reading a bit-based image block of an image from a memory. The bit-based image block is transferred, according to the next data transfer instruction, from the memory via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer. Then, the write buffer pointer is toggled to point to another of the pair of alternate buffers and the process repeats. The bit-based image blocks alternately stored in the buffers are later retrieved and displayed on the LED display.

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.

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.
