Card Led ThinkSTV-TH-K5Pro

Overview

TH-K5Pro is a small pixel pitch and high-end receiving card developed by Thinkstv.

TH-K5Pro single card can load up to 512×384 pixels and support up to 32 groups of parallel data or 32 groups of serial data, which can be expanded to 128 groups of serial data. With the small pixel pitch design, TH-K5Pro is suitable for small cabinet space and small pitch applications; it adopts high-density interfaces, and is dustproof and shockproof, and thus has high stability and high reliability.

TH-K5Pro has not only the functions of mainstream receiver cards, but also a series of practical and strong functions developed for high-end displays, increasing the additional value of the card. TH-K5Pro can be perfectly used in high-end rental displays and LED screens with small pixel pitch.

Feature details

Display effect
8bit	Support 8bit color depth video source input and output, monochrome grayscale is 256, can be matched with 16777216 kinds of mixed colors.
Frame rate	Adaptive frame rate technology, not only supports 23.98/24/29.97/30/50/59.94/60Hz regular and non-integer frame rates, but also outputs and displays 120hz high frame rate pictures, which greatly improves picture fluency and reduces drag film. (Note: it will affect the load).
Color temperature adjustment	Support adjustment of color temperature, that is, saturation adjustment, to enhance the expressiveness of the picture.
Better gray at low brightness	By optimizing the gamma meter algorithm, the display screen can maintain the integrity and perfect display of gray scale when reducing the brightness, showing the display effect of low brightness and high gray scale.
8bit calibration	8bit precision brightness and chromaticity correction point by point, which can effectively eliminate the chromatic aberration of the lamp point, ensure the uniformity and consistency of the color brightness of the entire screen, and improve the overall display effect.
Shortcut operation
Cabinet highlight	Using the control software, you can quickly mark the selected target cabinet, display a flashing box on the front of the cabinet, and change the flashing frequency of the cabinet indicator at the same time, which is convenient for front and rear maintenance.
Quick OSD	Using the control software, you can quickly mark the actual hardware connection serial number of the receiving card corresponding to the Ethernet port, which is convenient for setting the connection relationship of the screen.
Image rotation	Support the single cabinet image to be rotated at 90°/180°/270° angles, and with part of the main control, the single cabinet image can be rotated and displayed at any angle.
Data group offset	Supports screen offset in units of data groups, suitable for simple special-shaped screens.
Smart module	Support 8-way of intelligent module to save calibration coefficients and other information on module.
Hardware monitoring
Bit error detection	It supports the detection of data transmission quality and error code between receiving cards, and can easily and quickly identify the cabinet with abnormal hardware connection, which is convenient for maintenance.
Temperature monitoring	It supports cabinet temperature monitoring (requires cabinet design), can be sent back to the upper computer in real time, can be viewed on the software and supports custom setting of high temperature reminder. In addition, support 1-way receiving card’s own temperature monitoring without peripherals.
Humidity monitoring	It supports cabinet humidity monitoring (requires cabinet design), can be sent back to the upper computer in real time, can be viewed on the software, and supports custom humidity abnormality reminders.
Power supply monitoring	It supports the monitoring of 2-way power supply of the cabinet (requires cabinet design), which can be sent back to the upper computer in real time, can be viewed on the software, and supports the reminder of abnormal power status.
Voltage monitoring	Supports the monitoring of the power supply voltage of the box (requires cabinet design), which can be sent back to the host computer in real time, and can monitor the voltage status of 2-way of power supply at the same time, and support the software to check the voltage monitoring value. Support the monitoring of the power supply voltage of the receiving card, which can be returned to the host computer in real time, and support the software to check the voltage value.
Point-by-point monitoring	Supports point-by-point monitoring of the cabinet (requires cabinet design), can be sent back to the host computer in real time, can be viewed on the software, and supports the reminder of too many dead pixels on the lamp board.
LCD monitoring	Support control box LCD liquid crystal screen display, support temperature, voltage and running time and other status information display, support no-signal button self-test test.
Redundancy
Loop redundancy	The redundant Ethernet port is used to increase the connection with the transmitting equipment and increase the reliability of cascading between equipment. When one circuit fails, it can realize seamless switching to the other circuit and ensure the normal display of the screen.
Receiver card redundancy	Support to use two receiving cards to connect to the HUB board to control a single box at the same time. When the main receiving card is abnormal, the backup receiving card will work immediately to ensure the normal display of the screen.
Firmware redundancy	It supports firmware program backup and can be upgraded safely. There is no need to worry about the loss of firmware program due to cable disconnection or power interruption during the upgrade process.
