Problems solved by technology
[0011] The technical problem to be solved by the present invention is the problem of poor crimping of the connectors due to the different dimensions of the customer's products, the variety of connectors used, and the differences in the operating methods of the operators. The problem is that the short circuit of the connector cannot be completely solved by improving the accuracy of the structural parts and the proficiency of the personnel, and the cost is too high

Embodiment Construction
[0043] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0044]The invention discloses a power-on protection method for liquid crystal detection. The method comprises: powering on the liquid crystal screen, judging whether the current voltage value on the liquid crystal screen is the expected value; if the current voltage value is not the expected value, turning off the power Re-crimp the connector; if the current voltage value is the same as the expected value, continue to power on. Specifically, the step of judging whether the current power-on voltage is the expected value inc...

The invention discloses an electrification protecting method for liquid crystal testing. The electrification protecting method comprises the steps of electrifying a liquid crystal screen and determining whether the current voltage value on the liquid crystal screen is an expected value; and if the current voltage value is not the expected value, de-electrifying for connecting a connector in pressure connection again; and if the current voltage value is same with the expected value, performing electrification again. The invention further discloses an electrification protecting system for liquid crystal testing. According to the electrification protecting method, requirements for a structure precision aspect and a personnel proficiency aspect are prevented; whether a client product is in good pressure connection is determined by means of an electrical testing manner; and the product is electrified on the condition of good pressure connection, thereby effectively preventing a problem of product electrification in shortcircuit.
Description
technical field [0001] The invention relates to liquid crystal screen detection technology, in particular to a power-on protection method and system for liquid crystal detection. Background technique [0002] "Light, thin and compact" is the development trend of handheld consumer products in recent years. In order to achieve this goal, the miniaturization of the components used in the product is essential, including the connectors that connect the liquid crystal display and the main board of the product. The miniaturization of connectors has brought new challenges in the detection of liquid crystal displays. Since the adjacent contact points of connectors are very close, when the operator's technique is wrong or there is a slight deviation in the alignment mechanism, the backlight drive circuit's high The voltage is often connected in series to other adjacent input and output contacts, which may be other power supply voltages, ground wires or other digital signals.
