摘要： A display apparatus includes a timing controller, a column driver, a row driver and a display unit. The timing controller outputs a first column clock embedded into image data during an active period, and outputs a second column clock embedded into blank data during a blank period. The column driver detects the first column clock and the image data and converts the image data into a first analog signal using the first column clock, and detects the second column clock and the blank data and converts the blank data into a second analog signal using the second column clock. The first column clock has a voltage level greater than a voltage level of the image data. The second column clock is embedded into the blank data and has a voltage level substantially the same as the voltage level of the image data.

摘要： A light source module includes a plurality of light-emitting blocks. A local-dimming driver drives the light-emitting blocks based on a received clock signal (first reference clock) and received dimming levels. The clock signal is input to a liquid crystal display panel and is also input to the local-dimming driver but is delayed within the local-dimming driver by fixed propagation delay. A delay modeling part performs modeling of the fixed propagation delay amount. The clock signal input to the local-dimming driver is first phase-compensated (delayed) by a phase compensation amount to synchronize the driving signals output by the local-dimming driver with the clock signal. The sum of the modeled propagation delay amount and the phase compensation amount is equal to an integral multiple of the period of the clock signal. The driving signal of the light-emitting blocks are synchronized and in phase with the clock signal.

摘要： A wireless and multi-channel re-transmitting link is provided between an image displaying part that is housed in a first housing and an image data processing part that is housed in a segregated second housing. The wireless link allows the image displaying part to be more easily moved around and to be made lighter and slimmer in profile because at least some image data processing can be carried out in the second housing and yet cumbersome cables are not needed for linking the pre-processed image data from the second housing to the first housing. In one embodiment, the data bandwidth. that is to he transmitted through the wireless link is first reduced; for example the frame refresh rate of image frames conveyed through each of the wireless channels is made less than the frame refresh rate of the original image signal. In one embodiment, the reduced number of frames per unit time are further frequency wise and temporally wise spaced apart from one another by alternatingly sending them through different wireless channels at different times. Thus if a burst of noise strikes one of the plural re-transmission channels, the likelihood that it will corrupt a frame is reduced.
