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

[0069] 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 will be used in the drawings and description to refer to the same or like parts.

[0070] As used throughout this specification, 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 description of this case (including claims) are used to name components (elements), or to distinguish different embodiments or ran...

Abstract

The invention provides a driving device which comprises a reordering circuit and a source electrode driving circuit. The reordering circuit reorders a plurality of sub-pixel data of an input data string to generate a reordered data string so as to reduce the number of times of color switching of a target data line. The source driving circuit is coupled to the reordering circuit to receive the reordered data string. The source driving circuit drives a target data line of the display panel according to the reordered data string.

Description

[0001] This application is a divisional application of an invention patent application with an application date of January 22, 2020, an application number of 202010075669.2, and an invention title of "Driver Device for Display Panel and Its Operation Method". technical field [0002] 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 [0003] In a single-gate amorphous silicon panel (single gate α-Si panel), each sub-pixel column (sub-pixel column) is configured with a data line (source signal line). Compared with single-gate amorphous silicon panels, in a dual gate amorphous silicon panel (dual gate α-Si panel), every two sub-pixel columns 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 c...
