Embodiment
Fig. 1 is the summary block schematic diagram that illustrates according to a kind of display device of the embodiment of the invention.Display device comprises first time schedule controller 100, second time schedule controller 110 and source electrode driver 120.First time schedule controller 100 comprises transmitter 102; In one embodiment, transmitter 102 is low-swing differential signal (reduced swing differential signaling, a RSDS) transmitter.Second time schedule controller 110 comprises another transmitter 112; In one embodiment, transmitter 112 also can be low-swing differential signal (RSDS) transmitter.Two transmitters 102 and 112 are connected to bus 104 and 114, in order to transmit first pixel datas and second pixel data to source electrode driver 120 via bus 104 and 114 separately.
In addition, receiver 122 is recombinated to first pixel information and second pixel data according to a mode bus, operates for channel 124 to produce the 3rd pixel data.In one embodiment, receiver 122 is the data of optionally choosing in this first pixel data and second pixel data, operates for channel 124 as the 3rd pixel data with output.
Fig. 2 is for illustrating the sequential chart as data transmission among Fig. 1 according to the embodiment of the invention.At this, the representative of A bus is in order to transmit the bus 104 of first pixel data (being A0, A1, A2, A3...) from first time schedule controller 100, the representative of B bus is in order to transmit the bus 114 of second pixel data (being B0, B1, B2, B3...) from second time schedule controller 110, the C bus then is that representative transmits the bus (do not illustrate) of the 3rd pixel data to channel 124 for receiver 122.
At first, as an activation input/output signal (enable input/output, when EIO) starting, the first pixel data A0, A1, A2, A3... and the second pixel information B0, B1, B2, B3... are sent to receiver 122 in the source electrode driver 120 from first time schedule controller 100 and second time schedule controller 110 respectively.Then, the first pixel information A0, A1, A2, A3... and the second pixel information B0, B1, B2, B3... recombinate by the receiver in the source electrode driver 120 122, and the 3rd pixel information produces according to the reorganization result of the first pixel information A0, A1, A2, A3... and the second pixel information B0, B1, B2, B3....In the present embodiment, data transmission system is operated under three kinds of mode bus respectively, that is ABAB, AABB and AAAA pattern.When mode bus was the ABAB pattern, receiver 122 was optionally chosen the wherein one and second pixel information B0, B1, B2, B3... wherein of the first pixel data A0, A1, A2, A3..., with output as the 3rd pixel data.Particularly, the first pixel information A0, A1, A2, A3... and the second pixel information B0, B1, B2, B3... system be reassembled as the 3rd pixel information A0, B0, A1, B1, A2, B2, A3, B3 ... transmit for the C bus.In one embodiment, first time schedule controller 100 and second time schedule controller 110 all transmit pixel data with first time sequence frequency, receiver 122 then is to export the 3rd pixel data with second time sequence frequency to operate for channel 124, and wherein second time sequence frequency is two times of first time sequence frequency.
On the other hand, when mode bus is the AABB pattern, receiver 122 optionally choose the first pixel data A0, A1, A2, A3... wherein the two and the second pixel information B0, B1, B2, B3... wherein the two, with output as the 3rd pixel data.Particularly, the first pixel information A0, A1, A2, A3... and the second pixel information B0, B1, B2, B3... system be reassembled as the 3rd pixel information A0, A1, B0, B1, A2, A3, B2, B3 ... transmit for the C bus.
Another aspect, when mode bus was the AAAA pattern, second time schedule controller 110 lost efficacy (disabled), and only had first time schedule controller 100 to transmit the first pixel data A0, A1, A2, A3... to receiver 122.At this moment, the C bus only transmits pixel data A0, A1, A2, A3... or the like.By the embodiment of the invention described above as can be known, the method for application of aforementioned transmitted image data can be improved the efficient and the speed of image data transmission, uses the further operating speed of improving display device.
Though the present invention discloses as above with embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
