Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0046]In addition, if there are descriptions involving "first", "second" and s...

Abstract

The invention discloses a projector optical machine test system and method. The projector optical machine test system comprises a test terminal, an optical machine test platform and a data acquisitionburning board, wherein the test terminal is configured to output a duty ratio modulation signal during testing; the optical machine test platform is configured to place a projector optical machine tobe tested, and drive the projector optical machine to be tested to work according to the duty ratio modulation signal; the data acquisition burning board is configured to obtain a current brightnessvalue and a chromatic value of the projector optical machine to be tested, and the duty ratios of red, green and blue three-color LEDs in the projector optical machine under current brightness, and determine that the duty ratios of the red, green and blue three-color LEDs are set correctly when the current brightness value matches with a preset brightness value, and the projector optical machine does not generate color cast; and the test terminal is further configured to record the duty ratios of the red, green and blue three-color LEDs under the current brightness, and burn the duty ratios toa memory of the projector optical machine to be tested through the data acquisition burning board. In the invention, intelligence of projector optical machine testing is increased, manual operation is not needed, and problems that the intelligence of the projector optical machine testing is low and an operator operates inconveniently, and a recording error is easy to occur are solved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an optical-mechanical testing system and method for a projector. Background technique [0002] At present, the test method of the optical machine of the projector is usually a scheme of sampling current probe + oscilloscope + PC + burner. However, this test method needs to manually read the data and record it, import the recorded data to the PC, and then burn it to the programmer through the PC, which requires manual operation, low intelligence, inconvenient for operators, and easy There is a problem with logging errors. Contents of the invention [0003] The main purpose of the present invention is to provide a projector optical-mechanical testing system and method, aiming at improving the intelligence of the projector optical-mechanical testing. [0004] In order to achieve the above object, the present invention proposes a projector optical-mechanical testing s...
