Problems solved by technology

In this way, when the size of the display screen is larger and the resolution is higher, so that the number of segment lines and common lines increases, the number of panel drivers also increases; therefore, the power consumption of the driver circuit also increases accordingly.

Embodiment Construction

[0035] In order to make the structural features of the present invention and the achieved effects have a further understanding and recognition, preferred embodiments and detailed descriptions are specially used, which are described as follows:

[0036] Certain terms are used in the specification and subsequent claims to refer to particular components. It should be understood by those skilled in the art that hardware manufacturers may refer to the same component by different terms. This specification and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned in the entire specification and subsequent claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect means of electrical connection. Therefore, if it is described that a...

Abstract

The invention provides a drive circuit of a display. The display includes a plurality of first drive lines, a plurality of second drive lines and a plurality of liquid crystal capacitors, wherein each liquid crystal capacitor is arranged at the intersection of each first drive line and each second drive line. The drive circuit includes a time sequence controller for generating a plurality of time sequence control signals; N switches each of which is conducted or cut off according to the time sequence control signal, wherein the Nth switch is coupled to the first switch; and a driver which is coupled to the time sequence controller and, when each switch is sequentially conducted according to each time sequence signal, generates a plurality of drive signals sequentially according to each frequency control signal to charge each liquid capacitor, wherein, when the current liquid crystal capacitor is charged, charges stored in a previous liquid crystal capacitor is transferred to the current liquid crystal capacitor.

Description

technical field [0001] The present invention relates to a driving circuit, in particular to a driving circuit for a display. Background technique [0002] Advanced portable devices require display technology to meet low power consumption and high performance. In the past few years, mobile display technology has made rapid progress. The larger the size of the display screen and the higher the resolution, the corresponding increase in energy consumption. In addition, a better user interface, such as a graphical user interface and the use of touch controls, also prolongs the use time of the mobile display device, which makes the mobile display device must be more power-efficient to cope with its limited battery. Therefore, the power consumption of the display module must be reduced, especially for mobile display devices that need to continuously display data. [0003] Generally speaking, regardless of the active driving method or the passive driving method, the scanning electr...
