The invention discloses an automation method for programming a memory power source fru id and relates to a memory testing technology. The method is characterized in that an automation script compiled by a perl language under linux is used; hardware information is grasped by a serial port and an SAS line; in combination with the automation script, programming and testing of the memory power source fru id can be completed. The method mainly comprises the steps that (1) serial numbers of a memory case and I / O are scanned; (2) the I / O type is judged automatically, and a drive program is loaded automatically; (3) hardware is detected; (4) a serial number of the power source is scanned; (5) the power source fru id is programmed; (6) the programming is completed, and a machine is restarted automatically; and (7) after restarting, whether the fru id is programmed successfully is judged. According to the invention, unnecessary man-machine interaction courses are reduced; consumption of resources such as manpower, times and cost is reduced; testing efficiency and testing accuracy are increased; the coverage rate of the testing is very high; and product delivery quality can be ensured.

The invention provides a method for adjusting the common voltage of a liquid crystal display panel. According to the method, a red optimal common voltage, a green optimal common voltage and a blue optimal common voltage corresponding to a red flicker test image, a green flicker test image and a blue flicker test image are respectively found out; a red brightness weighting factor, a green brightness weighting factor and a blue brightness weighting factor respectively corresponding to a red pure-color image, a green pure-color image and a blue pure-color image are introduced, so that the optimal common voltage of the liquid crystal display panel can be calculated. With the method adopted, when the optimal common voltages of the liquid crystal display panel which are respectively corresponding to the red image, the green image and the blue image are inconsistent, difference among the optimal common voltages of the red image, the green image and the blue image can be offset through the red brightness weighting factor, the green brightness weighting factor and the blue brightness weighting factor, and therefore, the optimal common voltage of the liquid crystal display panel can be found out simply and conveniently, and the deviation of the optimal common voltage which is caused by the difference of response sensitivity of a photosensitive probe to light in different wave lengths can be decreased.

The embodiment of the invention provides a testing device capable of realizing automatic product code scanning. The test device comprises a rotation disc, a driving module group for providing rotation driving force for the rotation disc, a sensing module group and a code scanning module group, wherein the driving module group is connected with the rotation disc, a fixing module group is arranged on the rotation disc, when the rotation disc rotates to a first position, the sensing end of the sensing module group faces the fixing module group, and the driving module group is connected with the sensing module group to drive the rotation disc to rotate to a second position when the sensing module group senses that an objected to be tested is fixed on the fixing module group so that the objected to be tested enters into a code scanning area of the code scanning module group.
