Embodiment 1

[0048] figure 1It is a flow chart of a driving method provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the driving method includes:

[0049] Step 1. Divide the display area into a plurality of rectangular partitions, and form a first transition area between adjacent first partitions and second partitions.

[0050] figure 2 It is a schematic diagram of forming an overdrive partition in Embodiment 1, image 3 It is a schematic diagram of forming a transition region in Embodiment 1. Such as figure 2 with image 3 As shown, the display area is divided into a plurality of overdrive subregions according to the temperature distribution on the surface of the display panel, wherein a first transition region M2 is formed between the adjacent first subregion A and the second subregion B. It should be noted that this embodiment only describes the situation with two overdrive partitions, and other numbers of overdrive partitions, for example, four over...

Embodiment 2

[0067] Figure 5 It is a flowchart of a driving method provided in Embodiment 2 of the present invention, Image 6 It is a schematic diagram of forming an overdrive partition in Embodiment 2, Figure 7 It is a schematic diagram of forming the transition region in the second embodiment. see Figure 5-7 , according to the temperature distribution on the surface of the display panel, the display area is divided into a plurality of overdrive zones, the overdrive zone includes a first zone A, a second zone B, a third zone C and a fourth zone D, and the adjacent Between the first partition A and the second partition B, between the adjacent second partition B and the third partition C, between the adjacent third partition C and the fourth partition D A first transition area is formed between the adjacent fourth subregion D and the first subregion A, and the first transition region, the second subregion, the third subregion and the fourth subregion jointly define a second transitio...

Embodiment 3

[0082] This embodiment provides a driving device, including a dividing unit, a first forming unit, a second forming unit and a driving unit. The division unit is used to divide the display area into a plurality of rectangular partitions, and a first transition region is formed between adjacent first partitions and second partitions. In this embodiment, the division of the display area is realized through human eye observation based on manual debugging. The dividing unit may include a counter and a register. The counter is used to count the corresponding data lines and gate lines, so as to form the coordinate value of the pixel unit. The register is used to store the coordinate value. Finally, the display area is divided into multiple rectangular partitions through manual debugging.

[0083] The first forming unit is used to form a first partition overdrive table and a second partition overdrive table, the first partition overdrive table corresponds to the first partition, a...

Abstract

The invention discloses a driving method, a device, and display equipment. The driving method comprises the steps: forming a first subarea drive table and a second subarea drive table firstly, wherein the first subarea drive table is corresponding to a first subarea, the second subarea drive table is corresponding to a second subarea, and the matrix forms of the first and second subarea drive tables are the same; and carrying out the smoothing of the adjacent first and second subareas secondly through a first smoothing algorithm, so as to fuzzing the boundary of the first and second subareas, thereby effectively reducing or eliminating the boundary among a plurality of subareas.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method and device thereof, and a display device. Background technique [0002] In the existing display field, as the size of the display panel increases, the temperature on the surface of the display panel will be unevenly distributed, and the response time of the liquid crystal is related to the temperature. When performing 3D display, since the temperature distribution on the surface of a large-sized display panel is not uniform, local over-driving compensation (Local Over Driving Compensation) needs to be performed. Partition overdrive processing can well solve the problem of 3D display crosstalk caused by uneven temperature distribution on the surface of the display panel. However, when the overdrive compensation values ​​between the two partitions differ greatly, it will cause a display problem of the partition boundaries. Contents of the invention [...
