Be widely used in the various consumer electronics products in the MIPI standard, particularly the MIPI interface is used on the LCD screen, make LCD screen have slimming, characteristics such as low in energy consumption, widely applicable, reason owing to technical elements, a lot of producers that produce the LCD screen of MIPI interfaces are only detected the LCD screen, and the LCD screen of MIPI interface are not detected, when the LCD of MIPI interface screen broke down, what can't judge damage was that MIPI interface, LCD shield or both damage simultaneously.

Summary of the invention

The purpose of this utility model is at the problems referred to above, provides a kind of LCD screen to the MIPI interface to detect to society, and can to judge be that MIPI interface and one of LCD screen damage or the LCD screen pick-up unit of the MIPI interface that both damage simultaneously.

The technical solution of the utility model is: the LCD screen pick-up unit that designs a kind of MIPI interface, comprise MCU, the rgb signal of input is converted to the MIPI module of the MIPI signal of output, burning in advance has memory module and the backlight driver module of test procedure, described MCU respectively with described MIPI module, described memory module and described backlight driver module electrically connect, described MIPI module converts rgb signal to the MIPI signal, described MIPI module flows to described MIPI signal by first on-off circuit LCD screen of MIPI interface to be measured, the backlight work of the LCD screen of described backlight driver module drive MIPI interface to be measured, described MCU carries rgb signal for the LCD screen of described MIPI interface to be measured by described second switch circuit.

As to improvement of the present utility model, also comprise communication interface module, described communication interface module and described MCU electrically connect, and described MCU is burnt to test procedure in the described memory module by described communication interface module.

As to improvement of the present utility model, described communication interface module is usb interface module.

As to improvement of the present utility model, described communication interface module is the JTAC interface module.

As to improvement of the present utility model, described communication interface module is the com interface module.

As to improvement of the present utility model, also comprise pilot lamp, described pilot lamp and described MCU electrically connect.

As to improvement of the present utility model, the led light source of described pilot lamp is red, yellow, blue, green or white.

As to improvement of the present utility model, described first on-off circuit and described second switch circuit are touch switch, thumb-acting switch, single control switch or toggle switch.

The utlity model has the LCD screen that can detect the MIPI interface fast, and can to judge be that one of MIPI interface and LCD screen damages or both damage simultaneously, the user can add graph coloring according to self needs and detect, and has improved production efficiency and product quality, has reduced the advantage of production cost.
