Embodiment 1

[0037] figure 1 It is a flow chart of a display driving control method according to an embodiment of the present invention, see figure 1 , the method includes:

[0038] 101: receiving a hardware initialization instruction, so that the main controller enters the fast startup mode;

[0039] It should be noted that, according to the hardware initialization instruction, an initialization voltage enabling command of the display screen is sent, so that the display screen drive control circuit is powered by the low-voltage power supply ELVDD_2V.

[0040] 102: In the quick start mode, start the editing of the one-time programming instruction; specifically, receive the quick start instruction, and the quick start instruction carries the one-time programming instruction; realize the display of the main controller through the one-time programming instruction screen driver.

[0041] 103: Drive the display screen according to the editing content of the one-time programming instruction. ...

Embodiment 2

[0043] figure 2 It is a structural block diagram of a main controller according to an embodiment of the present invention, and the main controller 20 includes:

[0044] An instruction receiving unit 201, configured to receive a hardware initialization instruction, so that the main controller enters a fast startup mode;

[0045] A startup unit 202, configured to start editing of one-time programming instructions in the fast startup mode;

[0046] The driving unit 203 is configured to drive the display screen according to the editing content of the one-time programming instruction.

[0047] It should be noted that the main controller also includes: a command sending unit, configured to send an initialization voltage enabling command of the display screen according to the hardware initialization instruction;

[0048] The startup unit is specifically configured to receive a quick-start instruction, and the quick-start instruction carries a one-time programming instruction;

[...

Embodiment 3

[0051] image 3 It is a flow chart of a display driving control method according to an embodiment of the present invention, see image 3 , the display driver control method includes:

[0052] 301: Receive the analysis result of the one-time programming instruction;

[0053] 302: According to the analysis result, the display screen writes the initialization configuration file into the memory;

[0054] 303: Send an instruction to complete the initialization configuration file and write the memory to the main controller.

[0055] It should be noted that the method also includes:

[0056] Preset initialization start voltage threshold, delay time and initialization completion voltage threshold;

[0057] According to the analysis result, the step of writing the initialization configuration file into the memory by the display screen specifically includes:

[0058] According to the analysis result, detect whether the initialization voltage enable terminal voltage of the display scr...

Abstract

The invention discloses a display screen driving control method, a display screen driving control device and a display screen driving control circuit. The method comprises the following steps: receiving a hardware initializing command, so that a main controller can enter a fast boot mode; under the fast boot mode, starting editing of a one-time programmable command; and in accordance with edit contents of the one-time programmable command, driving a display screen. With the application of the technical scheme, display screen initializing time can be shortened, and in addition, a memory space of the display screen can be saved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a display screen drive control method, device and display screen drive control circuit. Background technique [0002] With the continuous development of power electronics technology, the types of power electronics products emerge in an endless stream, and more and more smart devices emerge as the times require. A very important reason why smart devices are widely used by people is reflected in the human-computer interaction function. Among them, the display screen has become an integral part of smart devices. Interact with people by touching the display of the smart device. Therefore, in the development process of smart devices, the debugging of the display screen is particularly important. [0003] At present, Android is the most widely used operating system for mobile smart devices, and most of the display drivers are based on the display architecture of the Androi...
