An optical parameter measurement device and a corresponding method are provided. A light beam from a to-be-tested display panel is split by a beam-splitting assembly into at least two testing light beams. A voltage value corresponding to a first testing light beam is measured by a trans-impedance amplification circuit corresponding to a first optical sensor. Next, an integration time period is determined by a control circuit according to voltage values from the trans-impedance amplification circuit and a predetermined relational model between voltage values corresponding to the light intensities and integration time periods. A voltage value corresponding to a second testing light beam is finely measured by the integration circuit corresponding to a second optical sensor within the integration time period. Finally, the display brightness value of the to-be-tested display panel is determined by the control circuit according to a voltage value from the integration circuit within the integration time period.

Optical parameter measurement device and optical parameter measurement method

The present disclosure provides an apparatus and system for testing a touch screen, and an apparatus for controlling test of a touch screen. The apparatus for testing a touch screen comprises: a processor, a test signal collection interface unit, and an external communication interface unit, wherein the processor is connected to the test signal collection interface unit, and is configured to, after touch information is collected by the test signal collection interface unit, convert the collected touch information into a format which is recognizable by an intelligent device, and transmit the converted touch information to the intelligent device through the external communication interface unit. The apparatus for testing a touch screen according to the present disclosure enables the touch information to be correspondingly processed and displayed by a processor and a display of the intelligent device, respectively. In this way, as the processor of the apparatus for testing a touch screen per se needs not to perform corresponding data processing and analysis processes, a processor with low performance may be used to facilitate reducing the manufacturing cost of the apparatus for testing a touch screen.

Apparatus and system for testing touch screen and apparatus for controlling test of touch screen
