Embodiment Construction

[0040] First of all, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0041] When the embodiments of the present invention refer to ordinal numerals such as "first", "second", "third" or "fourth", unless they really express the meaning of order according to the context, they should be understood as merely distinguishing use.

[0042] Secondly, the driving method provided in the present application is suitable for display panels using direct backlight technology. Exemplary, such as figure 1 As shown, the display panel includes a backlight, a first integrated circuit (integrated circuit, IC) for driving the backlight, a touch panel (touch p...

Abstract

The present application provides a driving method and a display panel, which relate to the field of display technology and can solve the problem that the electromagnetic field generated when driving the backlight has an influence on the TP, resulting in touch failure. The method includes: the first IC sends a first driving signal to a block of the backlight source in each time period T1, and after X time periods T1 in one scan cycle, the first IC completes the N times of the backlight source Drive; the second IC sends a second drive signal to a block of TP in each time period T2, and after Y time periods T2 within one scanning cycle, the second IC completes M times of driving of TP; each The scanning cycle includes X time periods T1 and Y time periods T3, there is no overlap between every adjacent two time periods in the X time periods T1 and the Y time periods T3, and the time period T2 is located in 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, in particular to a driving method and a display panel. Background technique [0002] In the direct type backlight technology, light emitting diodes (light emitting diodes, LEDs) in the backlight are evenly arranged directly below the display area. The backlight source adopts a driving scheme synchronous with a liquid crystal display (LCD), and the backlight source is required to provide brightness in each scanning period of the LCD. In order to obtain a better display effect, the working frequency of the backlight source is generally 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] Currently, direct-lit backlight technology has not been used in small-sized products (such as smart phones or tablet products, etc.). The display panels of these small-sized products often include a touch panel (touch pane...
