Embodiment Construction

[0021] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0022] see Figure 2 to Figure 5 , this embodiment provides a driving method for improving image display quality, which is applied to a display panel. The display panel includes a first group of GIP circuits (GIP-A1...) and a second group of GIP circuits (GIP-A2...), and the first group The GIP circuit and each GIP circuit in the second group of GIP circuits are connected one by one in sequence, for example, GIP-A1 is connected to GIP-B1, GIP-A2 is connected to GIP-B2, and then connected to the pixels of the display panel. For existing display panels, generally there is only one set of GIP circuits, which are used to turn on the gates one by one, so that the luminous data is written to the pixels one by one, and the luminous data is m...

Abstract

The invention discloses a driving method and device for improving image display quality. The method is applied to the display panel. The display panel comprises a first group of GIP circuits and a second group of GIP circuits. The GIP circuits in the first group of GIP circuits and the second group of GIP circuits are connected one by one according to a sequence; the driving method is characterized in that a first group of GIP circuits and a second group of GIP circuits are connected and then are connected with pixels of a display panel, the first group of GIP circuits and the second group ofGIP circuits are equally divided into a plurality of groups with the same number, and the driving method comprises the following steps: sending light-emitting data in a pulse mode through one group ofthe first group of GIP circuits; after the light-emitting data of the group is sent, black insertion data is sent through a group of a second group of GIP circuits connected with the group; and afterthe black frame insertion data is sent, the light emitting data is sent through the next group of the first group of GIP circuits. According to the invention, the blurring of the dynamic picture canbe reduced (the MPRT value is reduced), and the image quality is improved.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a driving method and device for improving image display quality. Background technique [0002] With the development of science and technology, the requirements for displays are getting higher and higher, and people pay more attention to display quality. However, many liquid crystal displays will have a blurred effect when displaying dynamic images, which will make viewers feel uncomfortable. Such as figure 1 For a comparison of a group of normal images and motion blurred images, there are three key reasons for blurred images, namely: (1) image update frequency, (2) gray-scale to gray-scale response time, and (3) panel drive method. Today's panels are also using these three methods to improve the dynamic picture, and measure the value of the motion picture response time (MPRT) as a basis for comparison. The lower the value, the better. Currently, improving motion blur im...
