INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A method and a terminal for adjusting screen brightness include the follows. A target pressure value and a target touch duration of a touch operation performed in a touch area by a user is detected. A target brightness adjustment amount corresponding to the target touch duration is acquired according to a preset correspondence relationship between a touch duration and a brightness adjustment amount, when a preset condition is met. Screen brightness is adjusted based on the target brightness adjustment amount. ## Claims ### Claim 1 A method for adjusting screen brightness, comprising: detecting a target pressure value and a target touch duration of a touch operation performed in a touch area by a user; acquiring a target brightness adjustment amount corresponding to the target touch duration according to a preset correspondence relationship between a touch duration and a brightness adjustment amount, when a preset condition is met; and adjusting screen brightness based on the target brightness adjustment amount. ### Claim 2 (depends on 1) The method of claim 1, wherein the preset condition comprises: the target pressure value is greater than a preset pressure threshold. ### Claim 3 (depends on 2) The method of claim 2, wherein the touch area comprises a first preset touch area and a second preset touch area, and the first preset touch area and the second preset touch area are two areas that do not coincide. ### Claim 4 (depends on 3) The method of claim 3, wherein adjusting the screen brightness based on the target brightness adjustment amount comprises at least one of: decreasing the screen brightness based on a target brightness reduction amount when the touch operation is performed in the first preset touch area; and increasing the screen brightness based on a target brightness increase amount when the touch operation is performed in the second preset touch area. ### Claim 5 (depends on 4) The method of claim 4, wherein when the touch operation is performed in the second preset touch area, the preset condition further comprises: a current power value is greater than a preset power value. ### Claim 6 (depends on 2) The method of claim 2, wherein the preset condition further comprises: target fingerprint information input by the touch operation matches with preset fingerprint information. ### Claim 7 (depends on 6) The method of claim 6, wherein the preset fingerprint information comprises first preset fingerprint information and second preset fingerprint information, and the first preset fingerprint information is different from the second preset fingerprint information; and adjusting the screen brightness based on the target brightness adjustment amount comprises at least one of: decreasing the screen brightness based on a target brightness reduction amount when the target fingerprint information matches with the first preset fingerprint information; and increasing the screen brightness based on a target brightness increase amount when the target fingerprint information matches with the second preset fingerprint information. ### Claim 8 (depends on 1) The method of claim 1, further comprising: after adjusting the screen brightness based on the target brightness adjustment amount, outputting screen brightness excessive alarms when a current screen brightness value is greater than a preset brightness threshold. ### Claim 9 A user terminal, comprising: a first detecting unit, configured to detect a target pressure value and a target touch duration of a touch operation performed in a touch area by a user; an acquiring unit, configured to acquire a target brightness adjustment amount corresponding to the target touch duration according to a preset correspondence relationship between a touch duration and a brightness adjustment amount, when a preset condition is met; and an adjusting unit, configured to adjust screen brightness based on the target brightness adjustment amount. ### Claim 10 (depends on 9) The user terminal of claim 9, wherein the preset condition comprises: the target pressure value is greater than a preset pressure threshold. ### Claim 11 (depends on 10) The user terminal of claim 10, wherein the touch area comprises a first preset touch area and a second preset touch area, and the first preset touch area and the second preset touch area are two areas that do not coincide. ### Claim 12 (depends on 11) The user terminal of claim 11, wherein the adjusting unit is further configured to: decrease the screen brightness based on a target brightness reduction amount when the touch operation is performed in the first preset touch area; or increase the screen brightness based on a target brightness increase amount when the touch operation is performed in the second preset touch area. ### Claim 13 (depends on 12) The user terminal of claim 12, wherein when the touch operation is performed in the second preset touch area, the preset condition further comprises that a current power value is greater than a preset power value. ### Claim 14 (depends on 10) The user terminal of claim 10, wherein the preset condition further comprises: target fingerprint information input by the touch operation matches with preset fingerprint information. ### Claim 15 (depends on 14) The user terminal of claim 14, wherein the preset fingerprint information comprises first preset fingerprint information and second preset fingerprint information, and the first preset fingerprint information is different from the second preset fingerprint information; and the adjusting unit is further configured to: decrease the screen brightness based on a target brightness reduction amount when the target fingerprint information matches with the first preset fingerprint information; or increase the screen brightness based on a target brightness increase amount when the target fingerprint information matches with the second preset fingerprint information. ### Claim 16 (depends on 9) The user terminal of claim 9, further comprising: an output unit, configured to output screen brightness excessive alarms when a current screen brightness value is greater than a preset brightness threshold. ### Claim 17 A user terminal, comprising: a processor and a memory connected with the processor, wherein the memory is configured to store program codes, and the processor is configured to call the program codes stored in the memory to: detect a target pressure value and a target touch duration of a touch operation performed in a touch area by a user; acquire a target brightness adjustment amount corresponding to the target touch duration according to a preset correspondence relationship between a touch duration and a brightness adjustment amount when a preset condition is met; and adjust screen brightness based on the target brightness adjustment amount. ### Claim 18 (depends on 17) The user terminal of claim 17, wherein the preset condition comprises: the target pressure value is greater than a preset pressure threshold. ### Claim 19 (depends on 18) The user terminal of claim 18, wherein the touch area comprises a first preset touch area and a second preset touch area, the first preset touch area and the second preset touch area are two areas that do not coincide; and the processor configured to adjust the screen brightness based on the target brightness adjustment amount is further configured to: decrease the screen brightness based on a target brightness reduction amount when the touch operation is performed in the first preset touch area; or increase the screen brightness based on a target brightness increase amount when the touch operation is performed in the second preset touch area. ### Claim 20 (depends on 18) The user terminal of claim 18, wherein the preset condition further comprises: target fingerprint information input by the touch operation matches with preset fingerprint information.
