Therefore, when the liquid crystal module of the light measurement 4 needs to use a specific display signal specification, the aging test system needs to be able to The LCD module displays different specifications and provides different display. The above situation greatly increases the complexity and cost of the conventional aging test system. Furthermore, each of the display signals of the specific specifications (for example, the LVDS signal standard or the TTL signal standard) are connected by different connection interfaces, so that the conventional aging test system needs to have each of the specific specifications displayed. The connection interface of the signal and the connection line again increase the complexity and cost of the system. Secondly, each wafer (Ch i ρ ) and integrated circuit (1C) assembled in the liquid crystal module have different anomalies. Tolerance (IC Margin), in order to increase the reliability of the test, the burn-in test system should perform independent power level control for the wafers and integrated circuits in the liquid crystal module to test each wafer and integrated body. The reliability of the circuit 'to complete the component stress test. The conventional aging test system, because the power supply it supplies must be stabilized and regulated, even if the input power of the 200914857 aging test system is greater than the power of the work, it will be controlled to the working power # ^ ^, turn to each order 70 It is impossible to complete the stress test in the aging test. The conventional aging test system is limited. Therefore, an aging test mechanism and a needle without a specific pressure test are required; the liquid crystal display device of == is very desirable. 4 佳 佳 佳 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 A test # Another object of the present invention is to provide an image for display without being tested.

In the embodiment, the first output circuit is a Wi μ original, and the first boost circuit 310 adjusts the first output power by using a Pulse Width Modulation (Pulse: ldths Modulation) method. Generating a pulse width modulation signal and using the pulse; and adjusting the ^ and another internal specific waveform output to generate a complex control signal to return the duty cycle of the first boost current $31G In 200914857, the adjustment of the first round of power supply is implemented, and in the system, the first boosting circuit 31 0 enables the test system 3 to have the ability to dynamically control the output power according to the load state. It should be noted that the method for performing power control by the first boosting circuit 31 0 should not be limited to any of the first boosting circuit 31 0 to perform the first output power adjustment. The method can be implemented instead of the first boost circuit 31. The second boosting circuit 320 is electrically connected to the first boosting circuit 31, and receives an output power supply. The first output can be input by using a transformer or a capacitor and an inductor, etc., as needed. The power source is converted into a first, output power source for driving the gate driving device of the subsequent planar display device, and the second output power source can also output a voltage that is higher than the normal working specification to the subsequent surface (four) gate driving unit.
