The present invention discloses a method and device of gray scale correction of a display panel. The method comprises: assigning a plurality of test gray scales and a reference gray scale, detecting the actual brightness of each pixel when the display panel inputs each test gray scale and the reference gray scale, and calculating the test gray scale average brightness and the reference gray scale average brightness of the display panel; determining a first gamma value corresponding to each test gray scale according to the test gray scale average brightness and the reference gray scale average brightness; dividing the total gray scale into n gray scale areas, and determining a second gamma value corresponding to an ith gray scale area according to the first gamma value corresponding to each test gray scale located at the ith gray scale area; and determining the correction relative brightness of the pixel in any gray scale according to the actual brightness of any one pixel in the maximum gray scale and the second gamma value corresponding to each gray scale area. The method of gray scale correction of the display panel realizes correction of each pixel located at different gray scale areas through adoption of different second gamma values so as to improve the display quality of the display panel.

The invention discloses a filename information display method and device. The method has a concrete implementation mode that firstly, a checking request on a file is received; then, whether the filename information of the file cannot be completely displayed or not is judged according to a displayable length of the filename information, if the filename information cannot be completely displayed, at least one piece of feature information corresponding to the filename information is obtained, and the at least one piece of feature information is displayed in a preset region of a file display region. The at least one piece of feature information displayed in the preset region of the file display region can be enabled to be capable of showing the feature contents of the file, and the display precision of the filename information is improved.

The invention discloses a wearable portable power source and a power supply control method thereof. The wearable portable power source comprises a control module, a battery, a first charging module, a second charging module, a communication module and an electric quantity processing module. The first charging module comprises a driver and a first port, the driver is connected with the control module, the first port and the battery, and the first port is used for charging the battery. The second charging module comprises a voltage raising driver and a second port, the voltage raising driver is connected with the control module, the battery and the second port and used for raising the output voltage of the battery, and the second port is used for charging a terminal. The electric quantity processing module is used for adjusting the electric quantity value of residual electricity of the battery in real time according to a charging curve of the battery. The communication module is used for sending the adjusted electric quantity value of the residual electricity to the terminal so that the residual electricity can be displayed through the terminal. In this way, the residual electricity of the wearable portable power source can be accurately displayed in real time through the charged equipment.
