This method has obvious disadvantages: two sets of backlight modules, two sets of drive control and signal processing modules, two sets of separate power supplies and independent cable connections are required
[0006] The above design proposes a construction method of a double-sided liquid crystal display, but since the first panel 121 and the second panel 122 use printed circuit boards of different structures, the design and installation are more complicated, and the edge width of the liquid crystal display will be increased.

Embodiment 2
[0065] The backlight module 200 in the second embodiment is a double-sided light-emitting backlight module, which can be a double-sided backlight module formed by direct-type CCFL, EEFL, LED, etc. combined with optical materials such as a diffusion sheet and a light-enhancing film, or can be an edge-light type. The double-sided backlight module formed by CCFL, EEFL, LED, etc. combined with double-sided light guide plate, light-enhancing film, etc., can also be a backlight module formed by combining two back-to-back single-sided backlight sources; but the uniformity of light generated on both sides of the backlight module The brightness, brightness and other parameters should be basically the same.
[0066] In the second embodiment, the timing control circuit module is required to provide the same gate control signal (GCS), data control signal (DCS) and image data (R, G, B), and require the data driving circuit module 115 and the gate driving circuit module 113 of the first pan...

The invention discloses a front-back-display liquid crystal display system and a playing control method. The front-back-display liquid crystal display system comprises a printed circuit board, a first panel and a second panel, wherein the printed circuit board is integrated by a time schedule controller module and a gamma supply module; the printed circuit board is respectively connected with thefirst panel and the second panel by at least one flexible printed circuit board; a double-side luminous backlight module is arranged between the first panel and the second panel; and two paths of driving signals and voltages are simultaneously generated and respectively transmitted to the first panel and the second panel by controlling the common time schedule controller module and the gamma supply module on the printed circuit board, so that the first panel and the second panel arranged on the front side and the back side simultaneously display programs. The liquid crystal display system hasthe advantages of simple structure, higher integration and lower cost of the double-side driving control circuit.
Description
technical field [0001] The invention relates to a display device, in particular to a liquid crystal display system and a playback control method with a simple structure and capable of displaying front and back. Background technique [0002] At present, liquid crystal display products on the market, especially in large-size applications such as LCD TVs and monitors, are still mainly based on a single backlight source and single-sided display. However, for special applications, such as large supermarkets, airports, multimedia teaching rooms, etc., TVs and monitors used as publicity and display tools usually use two similar products placed back to back to achieve double-sided display. This method has obvious disadvantages: two sets of backlight modules, two sets of drive control and signal processing modules, two sets of separate power supplies and independent cable connections are required. [0003] At present, some patents or products are double-sided display, including doub...
