Abstract

The present disclosure provides a method for locating sub-pixel address, an address location device and a repairing device. The method includes: obtaining an address of a location sub-pixel which is located by a cursor of the address location device in a liquid crystal panel; and calculating an address of a target sub-pixel in one pixel to which the location sub-pixel belongs, by using a sub-pixel arrangement structure of the one pixel of the liquid crystal panel as well as the address of the location sub-pixel. The target sub-pixel is one sub-pixel which is unable to be located by the cursor.

4. The method of claim 3, wherein the address location device is provided with a first button and a second button, and the obtaining an address of a location sub-pixel which is located by a cursor of the address location device in a liquid crystal panel includes:

when receiving a first operation command input through the first button, obtaining the address of the location sub-pixel which is located by the cursor of the address location device in the liquid crystal panel,

wherein the preset condition includes receiving a second operation command input through the second button,

wherein when the address location device meets the preset condition, the calculating the address of the target sub-pixel in the one pixel to which the location sub-pixel belongs, by using the sub-pixel arrangement structure of the pixel of the liquid crystal panel as well as the address of the location sub-pixel, includes;

in response to receiving the second operation command input through the second button, calculating the address of the target sub-pixel in the one pixel to which the location sub-pixel belongs, by using the sub-pixel arrangement structure of the one pixel of the liquid crystal panel as well as the address of the location sub-pixel.

5. The method of claim 3, wherein the address location device is provided with a first button, and the obtaining an address of a location sub-pixel which is located by a cursor of the address location device in a liquid crystal panel includes:

when receiving a first operation command input through the first button, obtaining the address of the location sub-pixel which is located by the cursor of the address location device in the liquid crystal panel,

wherein the preset condition includes that another first operation command input through the first button is received again in a first time period after receiving the first operation command, or that the first operation command is a command input by long pressing the first button,

when the address location device meets the preset condition, the calculating the address of the target sub-pixel in the one pixel to which the location sub-pixel belongs, by using the sub-pixel arrangement structure of the pixel of the liquid crystal panel as well as the address of the location sub-pixel, includes;
