Problems solved by technology

However, due to the fact that the red, green and blue LEDs will decrease in brightness as the temperature rises during the use of the LED display, and the attenuation of the three colors is inconsistent at the same temperature, such as figure 1 As shown, when the LED display is used at different temperatures, there will be color cast, the white balance is inaccurate, the color is not realistic, the image cannot be accurately restored, and the display effect is poor. Therefore, when the LED display is used, the color of the initial screen Uniformity, but with the long-term lighting temperature rising, the LED display will appear color cast, and the color cast will become more and more serious as the temperature rises, and the temperature recognition and correction technology can improve the LED display as the temperature rises. The color cast is getting more and more serious, which can make the LED display screen continue to maintain excellent display effect

Embodiment 1

[0064] Please refer to figure 2 , Embodiment 1 of the present invention is: a display screen correction method, which can be applied to LED display screens, and the method includes the following steps:

[0065] S1: pre-store calibration data corresponding to different temperatures;

[0066] S2: Monitor the temperature of the display screen in real time through a temperature sensor; the display screen can be an LED display screen, and the temperature of the display screen can be the temperature of the LED display screen module or the temperature of the LED display screen box.

[0067] S3: Obtain corresponding calibration data according to the temperature;

[0068] S4: Calibrate the display screen according to the calibration data.

[0069]Furthermore, before leaving the factory, the LED display can decide whether to perform correction according to the effect of the screen body and customer requirements, and can mark whether to perform correction through the preset correction...

Embodiment 2

[0077] This embodiment is a specific application scenario of Embodiment 1.

[0078] The LED display screen in the present embodiment is provided with temperature sensor, single-chip microcomputer and Flash memory chip; The correlation table, the microcontroller can extract the corresponding correction data at different temperatures.

[0079] When the cabinet or module reaches a certain temperature, the single-chip microcomputer can extract the correction data of the cabinet or module in the Flash memory chip when the temperature is at this temperature, and the correction coefficient [R ij 〕 T , [G ij 〕 T , [B ij 〕 T Send it to the LED display, and the LED display can be calibrated. Among them, [R ij 〕 T Represents the red LED light R in row i, column j ij Correction coefficient when the box or module is at temperature T, [G ij 〕 T Indicates the green LED light G in row i, column j ij Correction coefficient when the box or module is at temperature T, [B ij 〕 T Rep...

Embodiment 3

[0082] Please refer to Figure 4 , this embodiment is a display calibration system corresponding to the above embodiments, including:

[0083] Pre-storage module 1, used for pre-storing calibration data corresponding to different temperatures;

[0084] The monitoring module 2 is used to monitor the temperature of the display screen in real time through a temperature sensor;

[0085] The first acquisition module 3 is configured to acquire corresponding correction data according to the temperature;

[0086] The calibration module 4 is configured to calibrate the display screen according to the calibration data.

[0087] Further, the temperature of the display screen includes the temperature of the display screen module and / or the temperature of the display screen box.

[0088] Further, it also includes:

[0089] A judging module 5, configured to judge whether correction is required according to a preset correction coefficient;

[0090] The execution module 6 is configured t...

Abstract

The invention discloses a display screen calibration method, a display screen calibration system and a computer readable storage medium. The display screen calibration method comprises the steps of pre-storing calibration data corresponding to different temperatures; monitoring the temperature of a display screen in real time through a temperature sensor; acquiring the corresponding calibration data according to the temperature; and performing calibration on the display screen according to the calibration data. According to the invention, the LED display screen can be ensured to display uniformly at different temperatures, so that a problem that the LED display screen is increasingly severe in color cast along with the rise in temperature is improved, the white balance is kept to be accurate, the color is true to life, the image is accurately restored, the LED display screen is enabled to continuously keep the excellent display effect, and good visual appreciation effect of customers is ensured.

Description

technical field [0001] The present invention relates to the technical field of display screens, in particular to a display screen correction method and system thereof, and a computer-readable storage medium. Background technique [0002] With the development of flat panel display technology to large area, digitization and high definition, LED calibration technology has been paid more and more attention by everyone. Calibration technology is also the key to ensure the uniformity quality of LED display. The quality of the correction effect directly affects the visual viewing effect of people. After using the correction technology to obtain a series of correction coefficients, upload the correction coefficients to the control system with correction function to achieve the uniform effect of the LED display after correction. However, due to the fact that the red, green and blue LEDs will decrease in brightness as the temperature rises during the use of the LED display, and the a...
