When the attribute value read from the terminal register is the transmittance of the touch screen, the corresponding relationship between the preset attribute value range and the brightness of the key lamp can be shown in table 2:
table 2: corresponding relation between light transmittance and key lamp brightness
| Range of light transmittance | Brightness of light |
| <＝80 | 8 |
| >80 and<＝90 | 7 |
| >90 | 6 |
after the terminal is assembled, the light transmittance stored in the register is determined, and if the light transmittance stored in the register in the terminal is 70, the table 2 is looked up, and the corresponding brightness is determined to be 8; if the light transmittance stored in the register in the terminal is 88, looking up the table 2, and determining that the corresponding brightness is 7; assuming that the transmittance stored in the register in the terminal is 95, table 2 is looked up to determine that its corresponding brightness is 6.

| IS2002 | 8 |
| IS2008 | 8 |
| IS2009 | 5 |
| WE0009 | 7 |
| WE0007 | 7 |
After the terminal IS assembled, the touch screen model parameters stored in the register of the terminal are determined, and if the touch screen model stored in the register of the terminal IS IS2002, the table 4 IS searched, and the corresponding brightness IS determined to be 8; if the touch screen model stored in the register in the terminal IS IS2008, looking up the table 4 and determining that the corresponding brightness IS 8; if the touch screen model stored in the register in the terminal is WE0009, looking up the table 4 and determining that the corresponding brightness is 7; if the touch screen model stored in the register in the terminal is WW0031, the table 4 is searched, and if the corresponding brightness is not found, the corresponding brightness is determined to be the default value 7.

| Black color | AAA1 | 8 |
| Black color | AAA2 | 8 |
| Black color | AAA3 | 9 |
| White colour | AAA1 | 6 |
| White colour | AAA1 | 6 |
In the table, the model of the touch screen represents the supplier code of the touch screen, and the content in table 5 represents the black touch screen, and the required brightness of the key light is different due to the difference of the suppliers. After the terminal is assembled, the color and model parameters of the touch screen stored in the register are determined, and if the color of the touch screen stored in the register in the terminal is black and the model is AAA1, the table 5 is searched to determine that the corresponding brightness is 8; if the color of the touch screen stored in the register in the terminal is black and the model is AAA2, looking up the table 5 and determining that the corresponding brightness is 8; if the color of the touch screen stored in the register in the terminal is black and the model is AAA3, looking up the table 5 and determining that the corresponding brightness is 9; assuming that the touch screen color stored in the register in the terminal is white and the model is AAA1, look up table 5 and determine that the corresponding brightness is 6.
In the implementation of the solution of the present invention, the definition of the model of the touch screen is not limited to the content exemplified in the embodiment, and those skilled in the art can easily think of changes or substitutions to obtain definitions of other touch screen model meanings according to the model examples exemplified in the embodiment, and different models may have different requirements on the brightness of the key lamp in some cases.
Meanwhile, in the above-mentioned correspondence table between attribute values and key lamp brightness in this embodiment, numerical values are used to represent brightness, and the larger the numerical value is, the larger the brightness of the key lamp that needs to be set is.

Furthermore, after the corresponding key lamp brightness is determined, the key lamp brightness of the terminal is controlled, and the current provided for the key lamp can be controlled according to the corresponding key lamp brightness, so that the purpose of controlling the brightness is achieved, and the larger the corresponding key lamp brightness is, the larger the current provided for the key lamp is.
Or the duty ratio of the current supplied to the key lamp can be controlled according to the corresponding key lamp brightness, so that the purpose of controlling the brightness is achieved, and the duty ratio of the current supplied to the key lamp is larger when the corresponding key lamp brightness is larger. When the voltage and current supplied to the key light are the same but are converted to different currents by different duty cycles, for example, half the time the voltage is supplied, half the time the voltage is not supplied, which is equivalent to half the current supplied, and accordingly, the key light brightness is reduced.
