Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display having a light-emitting diode backlight module and a correction unit. [Prior Art] A backlight unit of a liquid crystal display (LCD) can provide a light source required for a liquid crystal display. That is, since the liquid crystal panel of the liquid crystal display itself does not emit light, the performance of the backlight module in the liquid crystal display can determine the visual sense of the liquid crystal display. With the improvement of liquid crystal display manufacturing technology and the trend of large size and low price, in order to maintain market competitiveness, it is the latest trend to develop and design a new type of backlight module to make the backlight module meet high brightness and low power consumption. Generally, the light source of the backlight module of the conventional liquid crystal display is composed of a cold cathode fluorescent lamp (CCFL). However, since the color saturation of a cold cathode fluorescent lamp (CCFL) is not high, it has become a new trend to use a light emitting diode (LED) as a light source of a backlight module. Furthermore, the light source using the light-emitting diode as the backlight module has the advantages of high color saturation, thinning, and no mercury, and the light-emitting diode backlight module can be further advanced 6 < S > 1377554 With the driving method of the LCD panel for dynamic control to compensate the viewing angle of the liquid crystal panel and the limitation of the reaction speed, therefore, there is already a Weishang, the light-emitting diode backlight module is applied to the notebook computer screen and the liquid crystal. TV (LCD TV). Please refer to the first figure, which is a schematic diagram of the arrangement of the light emitting diodes in the backlight module of the light emitting diode. The light-emitting diode backlight module is formed by using a plurality of red (R), green (G), and blue (B) light-emitting diodes to be arranged in an alternating manner, and the layout between the light-emitting bodies (lay〇) Ut) Distance also affects actual color performance. Since the white light generated by the red (R), green (G), and blue (B) light-emitting diodes is close to the wavelength of the three primary colors of the light, the liquid crystal display assembled by the light-emitting diode backlight module has a higher Please refer to the second figure for the color saturation. The color gamut performance comparison diagram of the conventional cold cathode lamp backlight module and the light emitting diode backlight module is shown. The area 100 in the figure represents a schematic diagram of a color gamut, and the area defined by the broken line 110 represents the range of colors that can be expressed by a conventional cold cathode lamp backlight module. Furthermore, the area enclosed by the solid line 120 represents the range of colors that can be represented by the LED backlight module. Obviously, it can be seen from the second figure that the color range of the LED backlight module can be larger than that of the conventional cold cathode lamp backlight module. However, there is still a gap between the color performance of the LED backlight module and the color space of the region 100. Therefore, increasing the color expression range of the LED backlight module and controlling the actual color performance of the LED are Nowadays LCD operators want to solve the problem. The liquid crystal display with photodetectors having mounted and its correcting method is disclosed in U.S. Patent No. 7,068,333. The patent provides a photodetector in the liquid crystal display between the backlight source and the light blocking plate in the backlight module. However, the optical detector is located in the backlight source and the light barrier and cannot accurately measure the actual display brightness of the liquid crystal display' and the photodetector cannot be changed in response to the brightness change around the liquid crystal display. Furthermore, since the photodetector can only detect the brightness of a part of the backlight module and cannot detect the brightness of all areas in the liquid backlight module, the output of the photodetector is The detection result may be inaccurate with the brightness of the actual output of the backlight module.
