A method for calibrating a color gamut of a display screen includes: acquiring a brightness level of the display screen, and original red green blue (RGB) values of a color to be displayed by a pixel in the display screen; determining, according to the brightness level of the display screen and the original RGB values, corrected color coordinates; and determining a calibrated RGB values according to the corrected color coordinates, and driving, with the calibrated RGB values, light emission of the pixel in the display screen.

Method and device for calibrating color gamut of display screen, and electronic device

A display method is applied to electronic equipment including a display assembly. A display content displayed by the display assembly includes a background and an object for reading located on the background. The display method includes: differentiating grayscales of background pixels of the background; and displaying the background based on the background pixels with the differentiated grayscales, and displaying the object for reading.

Display method and device, and storage medium

The present disclosure provides a screen color conversion method, a storage medium, and an electronic device. The method can include when an adjustment operation for a correlated color temperature of a color in a screen is triggered, determining target Red-Green-Blue (RGB) coefficients according to a relation curve between the RGB coefficients and a correlated color temperature, and a target correlated color temperature corresponding to the adjustment operation. The relation curve reflects a relation between a tristimulus value of a white color displayable for the screen and a correlated color temperature determined based on a black body radiation locus, and a target conversion matrix between the tristimulus value and the RGB coefficients. The method can further include converting the color in the screen to a target color corresponding to the target correlated color temperature according to the target RGB coefficient.

A screen brightness adjustment method includes: determining a direction of brightness adjustment based on a screen brightness adjustment instruction, and controlling a brightness level of a screen and a grayscale parameter of an image displayed on the screen based on the direction of brightness adjustment, such that brightness of the screen is adjusted to target brightness desired by the screen brightness adjustment instruction.

Screen brightness adjustment method and apparatus, and storage medium

Sending apparatus, receiving apparatus, sending method, receiving method and sending and receiving system for supporting application based MMS. The body of an incremental MMS includes a dynamic data section of MMS, a static data indicator associated with the MMS, and a link tag between indicated static data and the dynamic data. The amount of the message quantity transmitted may be reduced because the changed section of the incremental MMS is sent directly via short message channel in dynamic data mode. In turn, the incremental MMS may be sent via short message channel instead of MMS channel due to the reduction of transmitted message, which further reduces the communication cost.
