Below in conjunction with specific embodiment, realization of the present invention is described in detail:
Embodiment one
Fig. 1 shows the realization flow of the method for the liquid crystal-spliced system brightness of adjustment that the embodiment of the present invention one provides, and details are as follows:
In step S101, the brightness value of each display unit in liquid crystal-spliced system, contrast value, backlight value are all adjusted to 100.
In the present embodiment, first 100% white field signal is inputted in display unit core module by signal generator, and then by the communication interface of debugging control end by being connected with display unit core module, such as serial ports, regulates the brightness value of each display unit in display unit splicing system, contrast value, backlight value to be 100.
In step s 102, monitor the brightness of each display unit, simultaneously the register value of adjustment corresponding to backlight value 100, until the brightness of each display unit all meets the benchmark preset.
In the present embodiment, debugging control end is connected by communication interface with colour temperature instrument, and this interface can be serial ports, the brightness that debugging control end is obtained from each display unit measurement by the probe of this serial ports Real-time Obtaining colour temperature instrument.Debugging control end can regulate register value corresponding to backlight value 100 in real time according to this brightness, until this brightness meets default benchmark, wherein, this benchmark is the representative value of the maximum whole-screen brightness specified in large-size screen monitors liquid crystal display specifications.Can certainly allow the error of part, in the present embodiment, the high-high brightness control errors that debugging produces is within 0 to 5nit.
By this step, in liquid crystal large screen splicing system, the brightness uniformity of each display unit is guaranteed, carry out the aberration consistency adjustment of liquid crystal large screen splicing system on this basis, the good subjective feeling of large screen splicing system aberration consistance is significantly improved.In addition, also make liquid crystal large screen splicing system dispatch from the factory and after sale adjustment in more flexible.
Concrete, the brightness obtained by the probe measurement of serial ports to colour temperature instrument CA210 of debugging control end is read, when reading brightness and being greater than default benchmark, debugging control end subtracts 1 operation to the register value corresponding to backlight value 100, and then the brightness read and the benchmark preset are compared, this process repeatedly, until the high-high brightness of each display unit meets default benchmark; When reading brightness and being less than default benchmark, debugging control end adds 1 operation to the register value corresponding to backlight value 100, and then the brightness read and the benchmark preset are compared, this process repeatedly, until the high-high brightness of each display unit meets default benchmark.
