Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0025] AMOLED mobile phones can use 3power power supply mode (such as figure 1 shown) or 4power power supply mode (such as figure 2 shown). In the 3power power supply mode, the external power supply only provides 1.8V to the drive IC, and the 1.8V is divided into two circuits of 1.8V and 1.2V inside the I...

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a driving circuit, a driving control unit and electronic equipment. In the invention, the driving circuit comprises a first node used for being connected with a to-be-driven component; the first port is used for being connected with a first power supply; the time delay circuit is connected between the first port and the first node; the second port is used for being connected with a second power supply; the compensation circuit comprises a first input interface, a second input interface and a compensation voltage output interface, the first input interface is connected with the second port, the second input interface is connected with the first port, and the compensation voltage output interface is connected with the first node. According to the driving circuit, the driving control unit and the electronic equipment provided by the invention, the problem of abnormal display caused by response time required by the compensation circuit can be avoided, and the reliability of the electronic equipment is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a driving circuit, a driving control unit and electronic equipment. Background technique [0002] Due to the influence of various factors, the output voltage of the driving circuit is unstable. For example, for the 4power power supply mode adopted by AMOLED mobile phones, due to factors such as external impedance changes or DVDD voltage jitter, the external DVDD may be less than that required by the RAM. The case of the minimum voltage value will cause the data in the RAM to be lost and the display will be abnormal. In the related art, a scheme of adding a compensation circuit to the driving circuit is proposed. [0003] The inventors have found that there are at least the following problems in the prior art: due to the response time required by the compensation circuit, there is still the problem of data loss in the RAM and abnormal display, and t...
