An essential part of a CRT monitor, the shadow mask significantly influences color quality. Understanding the vibratory behavior of this component is important to picture quality of today's flat screen designs.
SE/ALD™
Detailed 3-D finite element models are used to understanding the vibratory behavior of the shadow mask. Testing is used to generate baseline data for the current model and then establish targets for the new design. Once the model has been correlated with test data, Systems Engineering /Analysis Leads Design (SE/ALD™) drives development.
Experimentation with a variety of mask to frame attachment schemes or vibration isolators can be analyzed to understand their impact on the dynamic characteristics of the shadow mask.
Testing
Testing is an important part of the process. In order to collect vibration and temperature data on the shadow mask, non-contact transducers are used.
This can pose a challenge to the output of the sensor due to the effects of glass shape, thickness, and tinting. To support these requirements, ITI developed a custom Tension Mask Measurement System.
Results
The client quickly and inexpensively evaluated numerous designs selecting the best alternative for minimizing vibration on the shadow mask. As a result the client's monitor consistently delivers a clear distortion-free image.
