Referring to FIG. 2, in some embodiments, the method for testing a gamma voltage includes:

S10, acquiring the gamma voltage value generated by a gamma chip;

In the embodiments, the gamma circuit is generally composed of two parts. Regarding the first part, a total of 14 gamma voltage values V1-V14 are generated in the gamma resistor network string R0-R14 on the central control board, taking the analog voltage as the reference voltage. The second part generates voltages of all gray scales, by inputting these 14 gamma voltage values into a source current and combining the gamma resistor network string with the source current. For example, for 8 bit data, the gamma circuit on the central control board only generates 14 gamma voltage values which, when input to the source current, combines the gamma circuit in the source current to further generate a total of 256 reference voltages VL0-VL255. These 256 reference voltages respectively correspond to the voltage values of 256 gray scales. Generally, the gamma resistor network inside the source current would not be adjusted once determined during chip manufacturing process.

The debugging of the gamma circuit is to substantially acquire a required gamma voltage value by adjusting the gamma resistor network in the central control board, so that the gamma curve meets the requirements. In order to quickly complete the gamma debugging, the integrated circuit of the gamma curve may be digitally debugged by software.

In the embodiments, the preset voltage range may be a preset voltage range determined based on a preset gamma voltage value and a preset deviation value. For example, the preset gamma voltage value plus the preset deviation value to obtain an upper limit of the range, and the preset gamma voltage value minus the preset deviation value to obtain a lower limit of the range, forming the preset voltage range. The preset voltage range stored in the second storage space may also be a range preset based on a preset gamma voltage value before leaving the factory.

For example, the operation of stopping the gamma chip from generating the gamma voltage value may be set to stop the gamma chip from being generated in a preset time after receiving the stopping instruction, when being subsequent to the operation of outputting the prompt information.

In the embodiments, a gamma voltage value generated by the gamma chip and a preset voltage range of the gamma chip are acquired, and when the gamma voltage value is not in the preset voltage range, prompt information corresponding to the gamma voltage value is output to allow detection by testers.
