Problems solved by technology

Therefore, the backlight assembly of the traditional liquid crystal display device is designed to convert the line light source into a planar light source through layer-by-layer optical plates or optical film layers; however, after the light is reflected and transmitted through several layers, the overall light energy can be The utilization rate has already been depleted a lot. After passing through the polarizer and color filter of the liquid crystal panel layer, the overall light energy utilization rate has been consumed by nearly half, resulting in the liquid crystal display device being obviously inferior to the traditional one in terms of color saturation and image brightness. image tube display device

Embodiment Construction

[0029] see figure 2 , which is a schematic structural diagram of a liquid crystal display device 100 equipped with the dot matrix backlight assembly system of the present invention. As shown in the figure, the liquid crystal display device 100 includes a dot matrix backlight assembly 10, which is used to form a planar light source that each light point can be independently modulated; above the dot matrix backlight assembly 10, a black matrix (black matrix) layer is arranged. 20, used to block the light between adjacent light spots; the top of the black matrix layer 20 is a thin-film transistor (TFT) layer 30, which is used to form each pixel of the liquid crystal display device, and the pixel of the thin-film transistor layer 30 can be The number of light points of the dot matrix backlight assembly 10 or its multiples, so that each light point of the dot matrix backlight assembly 10 can correspond to one or n (n is a positive integer) pixels of the thin film transistor layer ...

Abstract

The invention discloses a driving system of aphototropism component of point matrix, which comprises the following parts: time-sequence controller, level driving circuit and vertical driving circuit,wherein the time-sequence controller provides a time-sequence signal to control the starting sequence and starting time of each optical point of the aphototropism component of point matrix; the leveland vertical driving circuit provides a needed driving power and starting time for each optical point of the aphototropism component of point matrix according to the time-sequence signal.

Description

technical field [0001] The present invention relates to a driving system of a backlight assembly, in particular to a driving system of a dot-matrix type backlight assembly. Background technique [0002] With the continuous improvement and evolution of liquid crystal display (LCD) process technology and the gradual maturity of mass production technology, LCD related products have gradually advanced from personal computer related fields to home appliances with the cost advantage after mass production and other consumer electronics fields. In recent years, fueled by the announcement of the advent of digital information in advanced countries, in the process of gradually replacing analog systems, an upsurge of LCD TVs to replace traditional CRT TVs is gradually taking shape. [0003] Although LCD TVs have the characteristics of high resolution, low power consumption, and extremely light and thin compared with traditional CRT TVs, their display performance of dynamic images and c...
