Embodiment 1

[0044] like figure 1 As shown, it is a flow chart of an OLED screen high-efficiency display method based on a low-end MCU according to an embodiment of the present application. The method includes:

[0045] If the frame switching condition is not met, execute step S1;

[0046] If the frame picture switching condition is met, step S2 is executed;

[0047] S1: Send the first frame of picture data directly to the OLED buffer memory, and display the first frame of picture by refreshing the screen;

[0048] S2: Clear the screen in the current screen refresh cycle, and send updated display data to the OLED buffer memory in the next screen refresh cycle;

[0049] Wherein, the first frame picture is a frame picture currently displayed on the OLED screen.

[0050] In the embodiment of this application, the cost of the product is greatly reduced by using a low-cost low-end MCU; at the same time, when the frame switching conditions are not met, the first frame is directly sent to the ...

Embodiment 2

[0079] The embodiment of the present application is basically the same as the embodiment 1, and the main difference is that: in this embodiment, the frame screen switching condition is specifically receiving a preset partial screen switching instruction.

[0080] Preferably, one preset partial screen switching instruction corresponds to one effective display area;

[0081] The effective display area corresponds to displaying a plurality of different fonts;

[0082] The plurality of different fonts are arranged in sequence, and upon receiving the preset partial screen switching instruction once, switching from one font in the plurality of different fonts to the next font in order to display in the effective display area .

[0083] Specifically, local adjustment buttons, such as temperature adjustment and appointment time adjustment buttons, are provided in the home appliances. In an effective display area, multiple different fonts can be displayed correspondingly, such as 0-9...

Embodiment 3

[0096] The embodiment of the present application is basically the same as the embodiments 1 and 2, and the main difference is that: in this embodiment, the frame image switching condition is: receiving a preset partial image switching instruction or a preset image switching instruction.

[0097] Specifically, the method of the embodiment of the present application includes:

[0098] If any one of the preset screen switching command or the preset partial screen switching command is not received, perform step S1: directly send the first frame of picture data to the OLED buffer memory, and refresh the screen to display the first frame of picture;

[0099] If the preset screen switching command or the preset partial screen switching command is received, perform step S2: clear the screen in the current screen refresh cycle, and send updated display data to the OLED buffer memory in the next screen refresh cycle.

[0100] Wherein, the step S1 specifically includes:

[0101] S11: Se...

Abstract

The invention discloses an OLED screen efficient display method based on a low-end MCU and a household appliance. The method comprises the steps: directly transmitting first frame picture data to an OLED buffer memory if a frame picture switching condition is not met, so as to refresh a screen to display a first frame picture; if the frame picture switching condition is met, carrying out screen cleaning in the current screen refreshing period, and sending updated display data to the OLED buffer memory in the next screen refreshing period, wherein the first frame picture is a current display frame picture of an OLED screen. According to the OLED screen efficient display method based on the low-end MCU and the household appliance, the cost is low, the OLED display requirement can be met, and the display effect is good.

Description

technical field [0001] The embodiments of the present application relate to the field of display technology, in particular to a low-end MCU-based OLED screen high-efficiency display method and household appliances. Background technique [0002] At present, the Organic Light Emitting Diode (OLED) display is self-illuminating, does not require a backlight, has high contrast, is thin in thickness, has a wide viewing angle, fast response, can be used for flexible panels, has a wide operating temperature range, and has a It is considered to be an emerging application technology for the next generation of flat panel displays due to its excellent characteristics such as simple manufacturing process. [0003] In the prior art, the OLED display generally adopts the method of refreshing the screen at regular intervals. Before each screen refresh (that is, sending frame picture data to the OLED buffer memory), the screen needs to be cleared first. However, clearing the screen requires ...
