In­tel ex­plains low-power dis­plays

IN­TEL WANTS ITS LOW POWER DIS­PLAY TECH­NOL­OGY TO BE­COME NEARLY UBIQUITOUS SOMETIME NEXT YEAR.

Nearly lost in the flood of In­tel an­nounce­ments (see page 11) at Com­pu­tex—in­tel’s 28-core chip, the 8086K An­niver­sary Edi­tion, and more—was some­thing a bit more fun­da­men­tal: the de­vel­op­ment of 1-watt dis­play pan­els, which will have a pro­found im­pact on bat­tery life.

In­tel said it is work­ing with In­nolux and Sharp to de­velop what it calls its Low Power

Dis­play Tech­nol­ogy, which op­ti­mizes the dis­play tech­nol­ogy, in­clud­ing the back­light and panel cir­cuitry, to halve power from a typ­i­cal power con­sump­tion of about two watts down to a sin­gle watt. They’ll be op­ti­mized for In­tel’s U- and Y-se­ries pro­ces­sors for ul­tra­books and ul­tra-low-power de­vices.

In the real world, that could ex­tend bat­tery life by as much as four to eight hours, ac­cord­ing to Josh New­man, the gen­eral manager of mo­bile in­no­va­tion seg­ments for In­tel. For lap­tops whose bat­ter­ies al­ready last a dozen hours or more, it could push the lap­top’s stamina to lev­els that ap­proach 20 hours or more de­pend­ing on the ex­ist­ing bat­tery, New­man ex­plained.

For­tu­nately, In­tel’s Low Power Dis­play Tech­nol­ogy doesn’t ap­pear to change the fun­da­men­tal na­ture of the panel them­selves. In­tel showed off pro­to­type lap­tops from Dell and HP with the LPDT panel tech­nol­ogy al­ready in­stalled. It sounds like those lap­tops will still be able to pro­ject all the light out­put users need—350 nits or so. What’s un­known (and prob­a­bly un­likely) is whether you’ll be able to run at full bright­ness and still achieve the long­est bat­tery life.

New­man said the first sys­tems with the dis­play tech­nol­ogy in­stalled would ap­pear on store shelves this hol­i­day sea­son. It’s un­clear whether LPDT pan­els will af­fect the prices of the lap­tops them­selves—that’s up to note­book mak­ers, New­man told Pc­world.

In­tel’s been fac­ing pres­sure from Qual­comm on the bat­tery front, as its Snap­dragon-pow­ered Al­ways Con­nected PCS ( go.pc­world.com/snpc) em­pha­size con­nec­tiv­ity and long bat­tery life—specif­i­cally 20 hours or more, the same range In­tel is tar­get­ing. With In­tel be­gin­ning to push 5G-equipped PCS for­ward in con­junc­tion with low-power tech­nolo­gies like LPDT, it’s go­ing to be a close fight. That’s good news for con­sumers, who will ul­ti­mately ben­e­fit.

In the real world, that could ex­tend bat­tery life by as much as four to eight hours, ac­cord­ing to Josh New­man, the gen­eral manager of mo­bile in­no­va­tion seg­ments for In­tel.

In­tel showed off pro­to­type PCS in an “open house” at Com­pu­tex. These lap­tops, from HP and Dell, use the Low Power Dis­play Tech­nol­ogy co-de­vel­oped with Sharp and In­nolux.
