Method for measuring brightness response characteristic of display screen of notebook computer

Abstract

The invention discloses a method for measuring a brightness response characteristic of a display screen of a notebook computer. The method is used for a system for measuring the brightness response characteristic of the display screen of the notebook computer. The system comprises an upper notebook computer and a lower-computer photoelectric amplification and data acquisition device, wherein the upper notebook computer is used for generating a test pattern on the display screen of the upper notebook computer, the lower-computer photoelectric amplification and data acquisition device is used for converting, amplifying, acquiring and transmitting optical signals on the display screen of the notebook computer, the digital quantity of the optical signals is transmitted to the upper notebook computer through a serial bus interface and is processed and calculated in the upper notebook computer. The method is characterized by comprises an upper computer control method and a lower computer operation method. According to the invention, a system correction measuring flow is utilized to ensure measuring precision, and a fuzzy edge time measuring flow and a motion image response time measuring flow are used to verify the dynamic image quality of the display screen of the notebook computer.

Description

technical field [0001] The invention relates to a method for measuring the brightness response characteristic of a notebook computer display screen, which belongs to the technical field of display measurement. Background technique [0002] Based on the hold mode of liquid crystal display and the tracking characteristics of human eye observation, the current measurement methods of dynamic image quality are: (1) direct measurement method, (2) indirect measurement method. [0003] Direct measurement methods include high-speed camera method and tracking camera method. Although they can effectively simulate the smooth tracking of dynamic images by the human eye, the construction of such measurement devices is often due to the high precision of electromechanical matching, the high price of equipment configuration and the high cost of adjustment process. Difficult and difficult to achieve. [0004] The indirect measurement method is based on the measured transient brightness respo...
