Problems solved by technology

[0006] However, since the compensation value is set without considering the change in optical characteristics (such as color coordinates, correlated color temperature, etc.) of the LED during use of the LED, even if the driving signal is compensated on the basis of the compensation value, Also does not meet target white coordinates and target values

Abstract

The invention relates to a light generating device and display apparatus having the same. The display apparatus includes a light source driving part generating a driving voltage in response to a control signal, a light source part generating a light in response to the driving voltage, a display panel receiving the light to display an image, a measuring part receiving the light from the light source part to measure a spectral power distribution of the light, an extracting part measuring optical data by elements of the light source part on the basis of the spectral power distribution and extracting optical characteristics by the elements on the basis of the optical data, and a light source controlling part controlling the control signal on the basis of the optical characteristics.

Description

technical field [0001] The present disclosure relates to a light generating device and a display device having the same. More specifically, the present disclosure relates to a light generating device capable of extracting optical characteristics (such as color coordinates, correlated color temperature, etc.) of a light source section and a display device having the same. Background technique [0002] Generally, a liquid crystal display device includes a liquid crystal display panel displaying images using light transmittance of liquid crystals and a backlight assembly disposed under the liquid crystal display device to provide light to the liquid crystal display device. [0003] The backlight assembly includes a light source that generates light required to display images on a liquid crystal display panel, and in recent years, light emitting diodes having low power consumption and high color reproducibility are used as light sources. Light emitting diodes include red, green...
