FIELD: physics.
SUBSTANCE: method, relating to a liquid crystal display, having a layer (2) of light-emitting diodes, a diffusion layer (4) and a liquid crystal display layer (6), is meant for generating a backlight image. First, an image having colour channels for a first colour channel and a second colour channel is received. The transmission coefficient of the liquid crystal display layer (6) for the plurality of colour channels is determined for direct viewing and lateral viewing. The first and second ratios for direct and lateral viewing, respectively, are determined based on the transmission coefficient. The ratios are output signal of the liquid crystal display for the first colour channel and the second colour channel. The difference between the first ratio and the second ratio is determined and in order to minimise the difference, backlight illumination and the code value of pixel elements of the light-emitting diode layer (2) are controlled.
EFFECT: reduced colour shift.
