Problems solved by technology

However, according to the layout of the panel, the same data line often drives sub-pixels of different colors, that is, the source driver needs to frequently switch color data for the same data line
The more color switching times of the same data line, it means that the source driver constantly changes the voltage level of the source signal, so the power consumption of the source driver will also be more

Embodiment Construction

[0076] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and descriptions to refer to the same or like parts.

[0077] As used throughout the specification of this application, including the claims, the term "coupled (or connected)" may refer to any means of connection, direct or indirect. For example, if it is described that a first device is coupled (or connected) to a second device, it should be interpreted that the first device can be directly connected to the second device, or the first device can be connected through other devices or The second device is indirectly connected to the second device through some connection means. Terms such as "first" and "second" mentioned in the entire specification of this application (including claims) are used to name components (elements), or to distinguish dif...

Abstract

This disclosure relates to techniques for a driving apparatus including a reordering circuit and a source driving circuit. The reordering circuit can be configured to reorder a plurality of sub-pixeldata of an input data string to generate a reordered data string so as to reduce a color switching number associated with a target data line. The source driving circuit can be coupled to the reordering circuit to receive the reordered data string. The source driving circuit can be configured to drive the target data line of a display panel according to the reordered data string.

Description

technical field [0001] The present invention relates to a display device, and in particular to a driving device of a display panel and an operation method thereof. Background technique [0002] In a single gate amorphous silicon panel (single gate α-Si panel), each sub-pixel row (sub-pixel column) is configured with a data line (source signal line). Compared with a single-gate amorphous silicon panel, in a dual gate α-Si panel, every two sub-pixel rows share one data line, so as to reduce the number of data lines. However, according to the layout of the panel, the same data line often drives sub-pixels of different colors, that is, the source driver needs to frequently switch color data for the same data line. The more color switching times of the same data line, it means that the source driver constantly changes the voltage level of the source signal, so the power consumption of the source driver will also be more. [0003] It should be noted that the content in the parag...
