Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0031] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a TCONLESS main board signal conversion device and a detection system. An SOC chip is arranged in a TCONLESS main board, a signal switching test point and a screen signal output interface are arranged on the TCONLESS main board, and when the signal switching test point is at a first level, a screen signal is switched through the SOC chip to obtain a to-be-converted screen signal; the screen signal output interface is connected with the signal adapter plate and sends the to-be-converted screen signal to the signal adapter plate; and the signal adapter plate is connectedwith the test device, and converts the to-be-converted screen signal into a preset signal compatible with the test device through line sequence conversion. Through signal conversion of the TCONLESS main board and the signal adapter plate, signals needing to be detected are compatible with the test device, then the test device is compatible with a common liquid crystal screen, the technical problemthat main board detection needs to be completed through a special liquid crystal screen is solved, and the detection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a TCONLESS main board signal conversion device and a detection system. Background technique [0002] When the LCD TV is normally displayed, the TCON (Time Control, logic board) generally needs to provide DATA data signals and drive control signals that can be directly used by the LCD screen. At present, there are two main forms of TCON in the TV market: one is a separate TCON, and there is a separate TCON board near the LCD screen, which converts the output signal of the TV main board and sends it to the LCD screen. The other is the TCONLESS solution. The TCON is built into the main board of the TV, and directly outputs P2P (Point to Point, point-to-point) signals to the LCD screen for display. [0003] With the development of technology and increasingly fierce market competition, the market has put forward higher requirements for the cost of LCD TVs. Integrating ...
