PIXEL STRUCTURE FOR ELECTRONIC DISPLAY AND ELECTRONIC DEVICE CONTAINING SUCH DISPLAY Russian patent published in 2023 - IPC H01L33/50 H01L25/75 

FIELD: pixel structures.

SUBSTANCE: invention relates to a pixel structure for an electronic display, the pixel structure comprising at least one light-emitting diode (LED) emitter and at least one wavelength conversion unit disposed on a substrate. The result is achieved in that the pixel structure (1) contains a substrate (3), at least one LED emitter (4) located on the substrate (3), and at least one wavelength conversion unit (5) located on the substrate (3) next to the LED emitter (4). The LED emitter (4) is configured to emit emission radiation (R1), wherein the emission radiation (R1) is within the emission wavelength range and is emitted in one or more emission directions (D2, …, Dn) within the main emission plane (P1). The wavelength conversion unit (5) is configured to convert emission radiation (R1) into converted radiation (R2) within a converted wavelength range, wherein the converted wavelength range is different from the emission wavelength range. The converted radiation (R2) propagates from the wavelength conversion unit in a main conversion direction (D1) perpendicular to the plane of the main radiation (P1), wherein the main conversion direction (D1) is, for example, towards the user of an electronic device having an electronic display with at least one such pixel structure. Each pixel structure may contain six LED emitters (4), wherein the first pair of LED emitters (4) is operatively connected to the first wavelength conversion block (5), the second pair of LED emitters (4) is operatively connected to the second wavelength conversion block (5) and the third pair of LED emitters, each LED emitter of the third pair emits emission radiation directly in the main conversion direction (D1) or is operatively connected to the radiation dispersion unit 6 or the additional wavelength conversion unit 5.

EFFECT: increasing the luminous efficiency of the pixel structure of an electronic display.
