Abstract
The invention relates to an intelligent color LCD display device and a method for modulating by using columns and multicolor backlight. The display device makes a mono-driver generate a plurality of programmable segmental voltage signals, and partial segmental voltage signals can be modulated to generate a common voltage signal and at least two synchronous color separation backlight driven signalsafter a multicolor backlight modulating device is input so as to drive a backlight source to radiate the backlight in different colors. Therefore, the common voltage signal can be matched with the segmental voltage signals to generate a differential voltage so as to divide the time in the same mono-pixel to drive the mono-pixel to be illuminated or not and to synchronously radiate the backlight in different colors. The device can freely modulate overlaid colors on the mono-pixel by the visual overlaying effect generated by that the mono-pixel radiates the backlight with the different colors at different time and the characteristics of programmable change of the plurality of segmental voltage signals so as to produce an intelligent colorful display effect. Therefore, the single-color pixelcan form the multicolor display effect after being modulated by the device only through a mono display chip.

Embodiment
Relevant detailed content of the present invention now cooperates schematic view illustrating as follows:
See also Fig. 1, Fig. 2 and shown in Figure 3, device of the present invention comprises a single color LCD panel 10, a single-order driver 20, a multicolor backlight changing device 30 and a polychrome modulation backlight 40, wherein this single color LCD panel 10 has and sets up the up and down community electrode 11 and a plurality of split electrodes 12 of both sides separately, and have a plurality of single-order pixels 13 on this single color LCD panel 10, and to should common electrode 11 with the overlapping some setting of this split electrode 12, and as shown in the figure, be the example explanation with 16 single-order pixels 13.And this polychrome modulation backlight 40 has one and can penetrate at least two backlights 41 that different colours is backlight, and it is preferred forms for the backlight 41 that can produce red (R), green (G), blue colors such as (B).
See also shown in Figure 4, this single-order driver 20 can produce a plurality of sections voltage signals in regular turn according to sequential, the sections voltage signal is program-controlled, it can be according to demand by the mode program control change in addition of software, as shown in the figure, according to needing this single-order driver 20 to produce one first sections voltage signal 211, one second sections voltage signal 212, one the 3rd sections voltage signal 213 and one the 4th sections voltage signal 214.
See also Fig. 5 again, this first sections voltage signal 211, this second sections voltage signal 212, the 3rd sections voltage signal 213 is imported this multicolor backlight changing device 30 respectively with the 4th sections voltage signal 214, its via modulation after, can produce a common voltage signal 31 (XCOM) and quantity to should penetrating backlight color quantity and synchronous color separation backlight drive signal 32 by backlight, 33,34, its corresponding respectively driving backlight 41 sends (red (R) backlight of different colours, green (G), blue (B)), and allow this color separation backlight drive signal 32,33, it is backlight 40 that 34 inputs drive these polychrome modulations, allows this common voltage signal 31 and this a plurality of sections voltage signals import this common electrode 11 and these a plurality of split electrodes 12 respectively simultaneously.
And driving method of the present invention is as follows, at first prepares a single color LCD panel 10, a single-order driver 20, a multicolor backlight changing device 30 and a polychrome modulation backlight 40.
The a plurality of sections voltage signals that then allow this single-order driver 20 produce in regular turn according to sequential, this sections voltage signal is program-controlled, it can be according to demand by the mode program control change in addition of software.
Then allow this sections voltage signal import this multicolor backlight changing device 30 again, its via modulation after, produce the corresponding backlight 41 of a common voltage signal 31 and can penetrate backlight color quantity and synchronous color separation backlight drive signal 32,33,34 (being illustrated as three kinds of colors) with quantity.
It is backlight 40 that these color separation backlight drive signal 32,33,34 inputs of relief drive these polychrome modulations, allows this common voltage signal 31 and this a plurality of sections voltage signals import this common electrode 11 and these a plurality of split electrodes 12 respectively simultaneously.
