Abstract
The utility model discloses a control device for aging test, which comprises a test circuit connected with a test power source, and further comprises a timer and a switching circuit. The input terminal of the switching circuit is connected to the test power source, and electric signals are output to the test circuit. The switching circuit is also connected with the timer, and the timer can output signals to control the on-off of the switching circuit. The control device adopting the scheme has the advantages that the circuit is simple to be realized, the operation is convenient, the automatic switch test power source and the test time can be set optionally, and more convenience is provided for users.
Description
Technical field:
The utility model relates to a kind of controller, in particular is used for LED display and produces the time of the led light source burn-in test on the control display screen or the test control device of other index.
Background technology:
In the LED display production run, tend to occur problems such as rosin joint and bad product after the welding of led light source and substrate, so also need LED display is carried out the test step of rosin joint and bad product.Its theory is by the shock-testing of immediate current to led light source, differentiates problems such as rosin joint and bad product.Current all is switch motion and test duration by manually controlling test, brings many inconvenience to the user, also gives and has proposed new requirement in the industry.
The utility model content:
At the deficiencies in the prior art, the utility model provides LED display burn-in test control device, can arbitrarily set the automatic switch testing power supply and set the test duration, and its circuit is realized simple, and handling safety is brought more convenience to the user.
The utility model is implemented by the following technical solutions:
The burn-in test control device comprises the test circuit that is connected with testing power supply, it is characterized in that: also comprise a timer and an on-off circuit, the input end of described on-off circuit is connected to testing power supply, and the output electric signal is to test circuit.This on-off circuit also links to each other with a timer, the break-make of timer output signal gauge tap circuit.
Described on-off circuit is connected in parallel to the multi-channel test circuit, and the make-and-break time of described timer output signal gauge tap circuit is realized the setting of display screen test duration.
Burn-in test control device behind the employing such scheme, its circuit is realized simple, handling safety can arbitrarily be set the automatic switch testing power supply and set the test duration, brings more convenience to the user.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
According to accompanying drawing the utility model is described in further detail below:
Burn-in test control device as shown in Figure 1 comprises testing power supply, test circuit, timer and on-off circuit, and wherein the input end of on-off circuit connects testing power supply, and the output electric signal is to test circuit.On-off circuit also links to each other with a timer, the break-make of timer output signal gauge tap circuit.On-off circuit wherein can be connected in parallel to the multi-channel test circuit simultaneously, the make-and-break time of timer output signal gauge tap circuit, thus realize the setting of display screen burn-in test time.Burn-in test control device behind the employing such scheme, its circuit is realized simple, handling safety can arbitrarily be set the automatic switch testing power supply and set the time of testing, and brings more convenience to the user.
