Solution Overview

Problem

Mobile terminals experience prolonged unlocking times in screen-off mode due to light sensing and color temperature detection, affecting user experience.

Innovation Solution

The method involves receiving a biological password input, matching it with a preset password, and if matched, turning off light sensing and color temperature detection to immediately light up the screen using previous data, thereby bypassing tedious real-time environment detection.

VSEngineering Contradiction Analysis

1Illumination intensity

If light sensing and color temperature detection are turned on to ensure real-time data collection for screen brightness and color temperature adjustment, then display quality is improved, but unlocking time is prolonged

Engineering Contradiction:

Core Design Contradiction:
Illumination intensityVSLoss of time

Solution Approach 1:

The system pre-collects and stores light sensing data and color temperature detection data before the unlocking operation. When unlocking is triggered, the screen can immediately display using the pre-collected environmental data without waiting for real-time detection, thus reducing unlocking time while maintaining display quality

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the timing of light sensing and color temperature detection operations based on the unlocking state. By performing these detections before unlocking and storing the results for immediate use, the system optimizes the balance between display quality and unlocking speed

AI summary

A method for improving unlocking speed is provided. The method is applicable to a mobile terminal in a screen-off state and includes the following. An operation of entering an unlocking password by a user is received. Match the unlocking password entered and a preset password. A display screen of the mobile terminal is unlocked and lit up, at least after a successful match. The display screen of the mobile terminal is lit up by invoking light sensation data and color temperature data used when the display screen of the mobile terminal was lit up last time. A mobile terminal is also provided. With aid of the technical schemes of the disclosure, the unlocking speed is increased and user experience is improved.
