不發光，因此，液晶顯示器中背光模組的表現即可決定液 晶顯示器表現在外的視覺感。隨著液晶顯示器製造技術的 提升以及大尺寸與低價格的趨勢下，為了要保持市場競爭 力，開發設計新型的背光模組使得背光模組符合高亮度' 低消耗電力乃是最新的趨勢。 一般來說，習知液晶顯示器的背光模組的光源是由冷 陰極燈管(cold cathode fluorescent lamp，簡稱 CCFL)所 組成。然而，由於冷陰極燈管(CCFL)的色彩飽和度不高， 因此，利用發光二極體(light emitting diode，LED)來作為 背光模組的光源已經是新的趨勢。再者，利用發光二極體 作為月光模組的光源具有較兩的色彩飽和度、薄型化、以 及不含汞等優點，並且該發光二極體背光模組可再進—步 200923903 搭配液晶面板的驅動方式來作動態的控制用以補償液曰

INSTRUCTIONS: [Technical Field of the Invention] 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 crystai panei 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, the development of a new type of backlight module makes the backlight module meet high brightness. Low power consumption is the latest trend. 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 light source of the moonlight module has two advantages of color saturation, thinning, and no mercury, and the light-emitting diode backlight module can be further advanced to step 200923903 with a liquid crystal panel. The driving method is used for dynamic control to compensate for the viewing angle of the liquid helium panel and the limitation of the reaction speed. Therefore, it has now been: Hi-Lighting - The polar backlight module is applied to a notebook computer screen and a liquid crystal television (LCD TV). Please refer to the -®, which is a schematic diagram of the arrangement of the LEDs of the LED backlight module. The illuminating two-pole illuminating module is a plurality of red (R), green (6), blue (8) illuminating diodes arranged in an alternating manner and the layout between the Luguang ones (the (4) (four) distance will also change the actual color performance. Red (8), green (G), blue (8): The white light produced by the diode is close to the wavelength of the three primary colors of the light. Therefore, the liquid crystal display assembled by the LED backlight module has a higher color saturation / The second item of Mingcha Zhao's is shown as a comparison of the color gamut performance of the conventional cold cathode lamp backlight module and the standby light-polar body backlight module. The area (10) in the figure represents the color space (_r gamut). The schematic diagram, and the dotted line surrounded by the ^ domain no known conventional cold cathode lamp backlight module can represent the performance of the target area, in addition, the area enclosed by the solid line 120 represents the luminous diode moonlight group The range of colors that can be expressed. Obviously, the second figure shows that the color range of the LED backlight module can be larger than that of the conventional cold cathode lamp backlight module. Λ, ,: The color of the light-emitting one-pole backlight module 120 and the color of the area 100 There is still a gap in space, so increasing the color performance range of the LED backlight group and controlling the actual color performance of the LED is a problem that the liquid crystal display industry wants to solve. 200923903 For example, US Patent No. US 7,068,333 Liquid crystal display with photodetectors having mounted and its correcting method. The patent provides a light detection in a liquid crystal display to benefit from backlighting in a backlight module. Between the light source and the light barrier. However, the photodetector is located between the backlight source and the light barrier and cannot detect the actual visibility of the liquid crystal display, and the photodetector cannot respond to the perception of the liquid crystal display. In addition, because the light (four) omnipotent energy bond measures the brightness of part of the area of the backlight module towel, and can not be the free side of all areas in the hoof liquid backlight module, therefore, the light gamma (3) output The detection result may be inaccurate with the brightness of the actual rotation of the backlight module. [Summary] The purpose of the group and t ^ is Providing a liquid crystal display having a light-emitting diode backlight mode to increase the light-emitting diode backlight mode to emit the back display, comprising: a backlight module, wherein the light-emitting two-U panel and the light-emitting diode The back-filament source, the color of the light-emitting light d? first includes at least a plurality of interactively arranged embossed sheets, liquid helium, and a liquid crystal panel, the liquid crystal panel including a first pole therein, the thin; a transistor array substrate, a second polarizer; the solar array includes a plurality of neatly arranged pixels 8 200923903 and a plurality of internal photodetectors, each of the "transistive electrodes of an indium tin oxide film; - controlling 2 transistors, and connecting to the backlight module and the liquid crystal panel, the _== electric shirt like k 唬 produces corresponding control two according to the scan line on the column substrate ### ^ The crystal array W field., the corresponding control voltage ▲ corresponds to the transparent electrode of the indium tin oxide film on the flat crystal; and = film electricity = according to the internal light detector generated by the road - the first - Compensation money to find k, the younger brother, a compensation signal can be adjusted The light-emitting diode in ^ 'or color.

The backlight module fan includes a light-shielding plate (1) plus a shielding plate 2, 2, and a light-emitting diode backlight source 2〇4; wherein the light-blocking plate 2G2 reflects the light emitted by the backlight source 2G4 to the liquid crystal panel 210 for adding Uniform LCD brightness. The liquid crystal panel (10) includes a first polarizing plate 212, a glass 200923903 substrate glass substrate 214, a liquid crystal (called _crystal) 216, and a thin film transistor array substrate (thin_fi) m. The second polarizing film 219 is sealed between the glass substrate 214 and the thin film transistor array substrate 218. Of course, some specific liquid crystal panels use a color filter instead of the glass substrate 2M, that is, the liquid crystal 216 is sealed between the color filter and the thin film transistor array substrate 218. f Please refer to the _, which is shown on the thin film transistor array substrate ^ - pixel display; t @. The thin film transistor array substrate comprises a plurality of thin transparent germanium (TFT) 23 turns and a transparent electrode 235 of a tin tin oxide film.
