Abstract:
1. A method of correcting brightness of an electronic display that consists of a plurality of light-emitting components, comprising the steps of: A. capturing an imaging picture of the display, said capturing step comprising the following steps: A1. fixing photographic distance between the display and imaging units; A2. fixing photographic brightness of the electronic display; A3. focusing on the imaging units; A4. fixing photographic parameters of the imaging units; and A5. taking one or more photos of the electronic display by the imaging units to get the imaging picture of the display; B. getting characteristic parameters of each of the light-emitting components in the imaging picture of the display, said getting step comprising the following steps: B1. fixing locations of each of the light-emitting components at the imaging picture of the display; B2. fixing an imaging region of each of the light-emitting components at the imaging picture of the display; and B3. getting a grey value of each pixel in the imaging region of each of the light-emitting components and calculate the characteristic parameters of each of the light-emitting components; C. calculating a correction value of each of the light-emitting components with the characteristic parameters of each of the light-emitting components; and D. correcting the brightness of each of the light-emitting components with the correction value.
