Problems solved by technology

However, when the transmission speed becomes faster according to the demand, the electromagnetic interference (EMI) and power loss will also become higher due to the influence of the number of bit changes, that is, the influence of the toggle rate.

Embodiment Construction

[0015] According to an embodiment of the present invention, a method for sending image data to a driver in a display is provided, wherein the sent image data includes several pixel data, and each pixel data is represented by several bits, and each pixel data is One red, green or blue pixel data. The method includes sequentially sending at least two bits of one of the pixel data through a data line at a first cycle time; and sequentially sending the pixels through the data line at a second cycle time after the first cycle time. At least two digits of the other of the data. Wherein, the rank of the last bit sent in the first cycle time is the same as the rank of the first bit sent in the second cycle time. The following examples will be used for further explanation.

[0016] figure 2 It is a schematic diagram showing the waveform of pixel data when using the image data sending method according to the first embodiment of the present invention. As shown in the figure, each pixel ...

Abstract

Disclosed is a method for transmitting image data to a drive of a display, wherein the image data comprises a plurality of pixel data, and each pixel data is indicated by a plurality of bits. The method comprises sequentially transmitting at least two bits of one of the pixel data via a data wire in a first periodic time, and sequentially transmitting at least two bits of another pixel data via a data wire in a second periodic time closely neighboring the first periodic time, wherein the level of the last bit transmitted in the first periodic time is identical with the level of the first bit transmitted in the second periodic time.

Description

Technical field [0001] The present invention relates to a method of sending image data, and more particularly to a method of sending image data to a driver in a liquid crystal display. Background technique [0002] In a display system, the image data to be sent usually includes several pixel data, and these pixel data are generally sent one by one via several data lines. Specifically, when a bit of pixel data is being sent, its bit will be continuously transformed in time and sent from a sending device to a receiving device in parallel. [0003] figure 1 Represents the waveform diagram of the pixel data when it is sent in a general display system. As shown in the figure, the first and second bits of the first pixel data, namely R[0] and R[1], are sent sequentially via one of the data lines; the third and fourth bits of the first pixel data Bits, namely R[2] and R[3], are sent via another data line in sequence; and the fifth and sixth bits of the first pixel data, namely R[4] and ...
