Further, a difference value between the digital data of the two adjacent frame signals being smaller than the reference value indicates a still picture or a relatively flat moving picture.
Further, a difference between the digital data of the two adjacent frame signals being greater than the reference value indicates a fast moving picture.
Further, the micro control module is further configured to send the two adjacent frames of signals to the conversion module for conversion after judging that the difference between the digital data of the two adjacent frames of signals is smaller than the reference value.
Further, the system board is used for converting a signal of a signal generator into a VBYONE signal after receiving the signal of the signal generator.
The invention also provides a liquid crystal television which comprises the data processing device.

Detailed Description
The present inventive concept will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the inventive concept are shown. Advantages and features of the inventive concept, and methods of accomplishing the same, will become apparent from the following exemplary embodiments, which are described in greater detail with reference to the accompanying drawings. However, it should be noted that the inventive concept is not limited to the following exemplary embodiments and may be implemented in various forms. Accordingly, the exemplary embodiments are provided only to disclose the inventive concept and to let those skilled in the art understand the scope of the inventive concept. In the drawings, embodiments of the inventive concept are not limited to the specific examples provided herein.
Unless otherwise defined, all terms (including technical and scientific terms) used in the embodiments disclosed herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and do not need to be limited to the specific definitions known at the time of describing the present invention. Accordingly, these terms may include equivalent terms created after that time. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Referring to fig. 1 and 2, the preferred embodiment of the data processing apparatus of the lcd-tv of the present invention includes a system board 10 and a Timer Controller (TCON)30, wherein the timer controller 30 includes a receiving module 31, a micro-control module 33 and a converting module 35.
The system board 10 is configured to send a VBYONE signal to the receiving module 31, and the micro control module 33 is configured to convert each frame signal of the VBYONE signal into digital data, and generate a new frame signal according to the two adjacent frame signals to insert between the two adjacent frame signals after determining that a difference between the digital data of the two adjacent frame signals is greater than a reference value, and keep a time interval between the two adjacent frame signals unchanged. For example, in fig. 2, when the difference between the digital data of the nth frame signal and the digital data of the (N + 1) th frame signal is greater than a reference value, a new frame signal is inserted between the nth frame signal and the (N + 1) th frame signal, and the original (N + 1) th frame signal is changed into an (N + 2) th frame signal. The difference between the digital data of the two adjacent frames of signals greater than the reference value indicates a fast moving picture.
The micro control module 33 is further configured to send the two adjacent frame signals and the new frame signal to the conversion module 35, where the conversion module 35 is configured to convert the two adjacent frame signals and the new frame signal into Mini-LVDS signals and send the Mini-LVDS signals to a display device (not shown) for displaying.
When the difference between the digital data of the nth frame signal and the digital data of the (N + 1) th frame signal is smaller than the reference value, the micro control module directly sends the two adjacent frame signals to the conversion module 35 for conversion. And the difference value between the digital data of the two adjacent frames of signals is smaller than the reference value, so that the still picture or the relatively flat moving picture is indicated.
In this embodiment, the system board is used for converting a signal of a signal generator (not shown) into a VBYONE signal after receiving the signal of the signal generator.
While the invention has been shown and described with reference to certain embodiments, those skilled in the art will understand that: various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
