Embodiment Construction

[0040] First of all, the character " / " in this article generally indicates that the related objects before and after are an "or" relationship. The term "and / or" in this article is only an association relationship to describe the associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, it can mean that A exists alone, A and B exist at the same time, and A and B exist independently B these three cases.

[0041] When ordinal numbers such as "first", "second", "third" or "fourth" are mentioned in the embodiments of the present invention, unless they really express the meaning of the order according to the context, it should be understood as only to distinguish use.

[0042] Secondly, the driving method provided by the present application is suitable for a display panel adopting the direct type backlight technology. Exemplary as figure 1 As shown, the display panel includes a backlight, a first integrated circuit (IC) for driving th...

Abstract

The invention provides a driving method and a display panel, which relate to the technical field of display, and can solve the problem that the electromagnetic field generated when driving a backlightcauses the touch control to fail due to the influence of the electromagnetic field on the TP. The method comprises the following steps: a first IC transmits a first driving signal to a block of a backlight source in each time period T1; after X time periods T1 located in a scanning cycle, the first IC completes N times driving of the backlight source; the first IC transmits a first driving signalto a block of the backlight source in each time period T1; the second IC transmits a second driving signal to a block of TP in each time period T2, and after Y time periods T2 located in one scanningperiod, the second IC completes M times driving of TP. The second IC transmits the second driving signal to a block of TP in each time period T2. Each scan cycle includes X time periods T1 and Y timeperiods T3, there is no overlap between the X time periods T1 and every two adjacent time periods T3, the time period T2 is located within the time period T3, the backlight includes X / N blocks, and the TP includes Y / M blocks.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a driving method and a display panel. Background technique [0002] The direct type backlight technology is to evenly arrange the light emitting diodes (LEDs) in the backlight directly below the display area. The backlight source adopts a driving scheme synchronized with a liquid crystal display (LCD), which requires the backlight source to provide brightness during each scanning period of the LCD. In order to obtain a better display effect, the operating frequency of the backlight source is usually more than twice that of the LCD, that is, the backlight source is scanned more than twice in one scanning period of the LCD. [0003] At present, direct type backlight technology has not been used in small size products (such as smart phones or tablet products, etc.). The display panels of these small-sized products often include a touch panel (touch panel, TP), and ...
