Description
Technical field
The present invention relates to the LCD manufacturing and show the field, relate in particular to a kind of display panels and manufacturing approach thereof.
Background technology
TFT-LCD (Thin Film Transistor-Liquid Crystal Display; The TFT LCD) be to utilize the variation that is arranged on electric field intensity on the liquid crystal layer; Change the degree of the rotation of liquid crystal molecule, thereby the power of control printing opacity is come display image.In general, a complete display panels must have by backlight module, polaroid, color membrane substrates and tft array substrate, and the layer of liquid crystal molecule of filling in the box of being made up of their two substrates constitutes.
Now, in backlight module,, therefore replace traditional fluorescent lamp backlights just gradually because the white light LEDs backlight has advantages such as low in energy consumption.At present, the white light LEDs backlight that generally uses utilizes blue-light LED chip coupling yellow fluorescent powder or red green fluorescence powder to realize.
Because being the light by various wavelength, the white light that sends of white light LEDs backlight mixes; Therefore; During this white light process liquid crystal layer, the optical anisotropy of different wave length is different, and the light of each wavelength can form different bit phase delays; And cause producing colour cast thus, influenced the display effect of display panels.
Summary of the invention
Of the present invention a kind of liquid crystal color display panel is provided, the visible light that can avoid the different wave length that the conventional white light backlight transmits forms different phasic differences through liquid crystal layer and the display panel colour cast that causes.
For achieving the above object, the present invention adopts following technical scheme:
On the one hand; A kind of display panels is provided, comprises: LED-backlit source, to the color membrane substrates and the tft array substrate of box moulding, and the liquid crystal layer between said color membrane substrates and said tft array substrate; Said color membrane substrates comprises alignment films, common electrode layer and colored filter
Said LED-backlit source is a plurality of primary colors led chips;
Be provided with the phosphor powder layer that becomes complementary colors with said primary colors led chip between the alignment films of said color membrane substrates and the colored filter.
On the one hand, a kind of liquid crystal display panel preparation method is provided, comprises:
Make backlight with a plurality of primary colors led chips;
Make color membrane substrates; Be coated with the phosphor powder layer of the complementary colors of said primary colors led chip between alignment films on the said color membrane substrates and the colored filter;
With making good tft array substrate and said color membrane substrates to box, and between said tft array substrate and said color membrane substrates the filling liquid crystal layer;
Said backlight is arranged on said tft array substrate below.
The manufacturing approach of display panels provided by the invention, the LED-backlit source of display panels is the primary colors led chip, and between being coated in the phosphor powder layer of the complementary colors of primary colors led chip on alignment films and the colored filter.Like this, backlight send through liquid crystal layer be primitive color light, monochromaticity is good; Therefore phase delay much at one; See through colored filter through becoming white light via phosphor powder layer again behind the liquid crystal layer, thereby avoided display panels to produce colour cast, improved the display effect of display panels.
