Embodiment Construction

[0046] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0047] see figure 1 , the invention provides a method for manufacturing a COA type liquid crystal display panel, comprising the steps of:

[0048] Step 1, such as Figure 2-4 As shown, a TFT substrate 11 is provided. The TFT substrate 11 includes a first substrate 110, a TFT layer 111 disposed on the first substrate 110, and a passivation layer 112 disposed on the TFT layer 111. In the TFT A black matrix 12 is fabricated on the substrate 11, and the black matrix 12 divides the TFT substrate 11 into several sub-pixel regions 120, and the several sub-pixel regions 120 include several red sub-pixel regions 121, several green sub-pixel regions 122, and several blue sub-pixel regions 123 .

[0049] Specifically, the black matrix 12 simultaneousl...

Abstract

The invention provides a COA type LCD panel manufacturing method and a COA type LCD panel; the method uses responsive liquid crystal, responsive monomers, red quantum rods, and green quantum rods to form a color filtering film; the red and green quantum rods can be activated so as to generate polarized light, and are respectively arranged in a same direction, so red and green linearly polarized light of same polarization direction can be generated after backlight activation, thus providing lower polaroid effect; the COA type LCD panel prepared by the method can obtain brilliant three primary color light and improve saturation level, and the lower polaroid can be omitted so as to reduce production cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a manufacturing method of a COA type liquid crystal display panel and a COA type liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, TVs, personal digital assistants due to their advantages of high image quality, power saving, thin body and wide application range. , digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. Usually, the liquid crystal display panel is composed of a color filter (CF, ColorFilter) substrate, a thin film transistor (T...
