The LCD TV newly developed by the green and blue and red lasers in the RGB of the light source has a color reproduction range of about the current white LED TV product LCD-46MDR due to the use of a high-purity red laser that is easily recognized by the human eye. 1.3 times expansion. xvYCC can also be supported.
Maintaining the same characteristics of previous products in terms of brightness and contrast, as well as the power consumed, these technologies will be applied to future 3D TVs.
Red laser parts overview
Red laser components have been commercialized, with the exception of 300mW and a wavelength of 638nm. The red laser wavelength used in DVD is 650nm short in order to be more suitable for display products. This color has a better degree of reduction, for example, the performance of skin color can be more natural expression. Laser light source control technology has also been applied to televisions so far.
There are different combinations of directions in the direction of productization. How to combine the two light sources with different diffusion angles has become a topic, so an optical technology that can uniformly and independently illuminate the liquid crystal panels of the two light sources is developed. If the laser with a narrow divergence angle is directly irradiated with the LED, there will be uneven light, resulting in uneven color of the picture. Therefore, the development of the luminous intensity distribution of the laser light source uniformly illuminates the individual optical system of the panel, ensuring a balanced image color and achieving high image quality.
Comparison with Tongshe LCD TV LCD-46MDR
This time, the prototype product uses the same LCD panel as the previous model, and is suitable for color management technology and color matrix. The characteristic panel of the correction panel color, because the color and brightness signals are separated by the color of the matrix, the adjustment of the three primary colors plus the intermediate purple, yellow and cyan can be independently controlled. It is possible to make a matching color reproduction possible for the characteristics of the liquid crystal panel.
The productization of this laser LCD TV was originally a high value-added product. In the future, in the process of productization, we will find the most suitable illumination configuration for other light sources and improve the illumination method.
