An LED backlight, a backlight module, and a display apparatus are provided. The LED backlight includes: a substrate; a plurality of LED chips disposed on a first surface of the substrate and electrically connected to the substrate, where each LED chip includes a first light emitting surface disposed on a side of the LED chip facing away from the substrate and at least one second light emitting surface, and a plane where the at least one second light emitting surface is located intersects with the substrate; a plurality of prism-shaped light guide structures disposed between adjacent LED chips and in a space defined between two adjacent second light emitting surfaces of adjacent LED chips, where the prism-shaped light guide structures have an index of refraction of n1; and a first medium filling the space between the LED chips and the prism-shaped light guide structures.

LED backlight, backlight module, and display apparatus

A touch-control display device includes a driving module, a first substrate disposed with one or more first force touch-control components, and a second substrate disposed with one or more second force touch-control components and one or more self-capacitance type touch-control electrodes. The first substrate and the second substrate are oppositely disposed, with a variable gap between the first substrate and the second substrate. The second force touch-control component comprises a plurality of first electrodes arranged in a matrix, and the plurality of first electrodes are connected to the driving module respectively through their corresponding first conducting wires. The self-capacitance type touch-control electrode comprises a plurality of second electrodes arranged in a matrix, and the plurality of second electrodes are connected to the driving module respectively through their corresponding second conducting wires.

Touch-control display device

A touch-control display device includes a driving module, a display panel having a first force touch-control component and a self-capacitance type touch control-electrode, and a backlight module disposed with the display panel and having a second force touch-control component, with a variable gap formed between the first force touch-control component and the second force touch-control component. The first touch-control component comprises a plurality of first electrodes arranged in a matrix. The second force touch-control component is an electrical conductive layer. The self-capacitance type touch-control electrode comprises a plurality of second electrodes arranged in a matrix.
